SYSTEMS
by
Prabakar Marikani
This project work is focused on the study and possible resolution of interface
issues between the Texas Instruments TMS C6713 DSP Starter Kit (DSK) and computers
operating on Windows versions higher than XP, such as Windows 7, 8 and 10.
Essentially, the current issues to be resolved are the compatibility issues between earlier
model processors and the PCs operating on newer Windows versions.
In order to validate the resolution of these compatibility issues, experiments such as signal generation and digital filtering design/implementation will be tried out using the interface, and the results will be recorded. This work will be very useful for the
DSP curriculum in the EEE Department at Sacramento State.

INTRODUCTION
Code Composer Studio [4] is an integrated development environment (IDE) that
supports TI's (Texas Instruments) Microcontroller and Embedded Processors portfolio.
Originally Code Composer was a product from a company called GO DSP located in
Toronto, Canada, and it was acquired by TI in 1997. After the acquisition, Code
Composer was bundled with a real-time kernel named DSP/BIOS and its name was appended with the word Studio. Code Composer Studio contains set of designed tools used for developing and debugging various embedded applications.
The most important application of Code Composer Studio is to design embedded projects and to perform low-level (bare metal) JTAG based debugging. In recent years, unmodified versions with Eclipse open source IDE includes support for OS level application debug (Linux, Android, Windows Embedded) and open source compiler suites such as GCC [4].
This integrated development environment provides a user friendly interface which allows the user to interact with the application in each step of the project development. Environment like this allows the user to get used to the compiling and debugging tools faster than other environments. Code Composer Studio includes
2
important features like Eclipse software framework and advanced embedded debug
capabilities which provides rich user interacting development environment for embedded
developers. This integrated environment consists of optimizing C/C++ compiler, source
code editor, project build environment, debugger, profiler, and many other features used
for supporting TI’s Embedded Processor [8].
1.1 Introduction to TMS C6X DSP
TMS C6X DSP is one of the most powerful processors developed by Texas
Instruments. It is a low cost development platform mainly designed to increase the
development speed of high precision TI’s applications. This DSP Kit uses USB
communications for plug-and-play functionality. It provides innovative product designs with many features for both experienced and novice designers [1].
This Kit includes latest TI fast simulators and access to the Analysis Tool Kit
which contains Cache Analysis tool and Multi-Event Profiler. Cache Analysis is used for
providing optimized cache usage which helps to improve the application performance.
Cache optimization is achieved by providing graphical representation of the on-chip
cache activity over a period of time. By using this data user can get peak performance by
quickly determining whether their code using on-chip cache [8]. The DSK includes the
Fast Run Time Support libraries and utilities such as Flash burn to program flash, Update
3
Advisor to download tools, utilities and software and a power on self-test and diagnostic utility to ensure the DSK is operating correctly.
The DSK features the TMS320C6713 DSP, a 225 MHz device delivering up to
1800 million instructions per second (MIPs) and 1350 MFLOPS. This DSP generation is designed for applications that require high precision accuracy [9]. The C6713 is based on the TMS320C6000 DSP platform designed to needs of high-performing high-precision applications such as pro-audio, medical and diagnostic. Other hardware features of the
TMS320C6713 DSK board include [8],
Embedded JTAG support via USB
High-quality 24-bit stereo codec
Four 3.5mm audio jacks for microphone, line in, speaker and line out
512K words of Flash and 16 MB SDRAM
Expansion port connector for plug-in modules
On-board standard IEEE JTAG interface
+5V universal power supply
In order to study the compatibility issue between the DSP Kit and current PC windows system, we used sine wave generation program and FIR filter implementation program. The programs are written using C language in Code composer studio version
4
5.3.0 and we used Window’s 10 PC for this experimentation. The generation programs are compiled and implemented using the DSP Kit TMS320C6713.

EVOLUTON OF DSP IN COMMUNICATIONS
Evolution of Digital signal [2] processing includes introduction of large number of digital signal processing (DSP) products. DSP has become a key component in many consumer, communications, medical, and industrial products, which use a variety of hardware approaches to implement DSP, ranging from the use of off-the-shelf microprocessors to field-programmable gate arrays (FPGAs) to custom integrated circuits
(ICs). As wireless communication standards evolve, the demand for a digital signal processor (DSP) supplying computation with high performance, high flexibility and low power-dissipation is gaining momentum in various industries. The specification of early
DSP was to execute filter algorithm like Finite-impulse response filters, infinite-impulse response filters, Convolution and Correlation and Fast Fourier response. The main application of DSP [3] in communication is to perform mathematical operations on the digitally represented signals. In such applications DSP is powerful enough to outperform most of the general purpose processors for time critical applications. Most of the DSP tasks require repetitive numeric computations, real-time processing, high memory and system flexibility. The effective Digital Signal Processors are often more cost-effective than the other custom hardware, where the development cost of custom ICs may be prohibitive. DSP processors often have an advantage in terms of speed, cost, and energy efficiency.

Texas Instruments TMS320 is a general name given to a series of Digital Signal
Processors products produces by Texas Instruments. This DSP processor is available with different forms including Fixed-point arithmetic DSP, Floating-point arithmetic DSP and
Microprocessor DSP. This particular architecture has been around for a while and different products have been developed based on this architecture.
The product codes used by Texas Instruments [4] after the first TMS32010 processor have involved a very popular series of processor named TMS320Cabcd where “a’ is the main series, ‘b’ the generation and ‘cd’ is some custom number for a minor sub-variant. By using this naming method “C5X” is used as abbreviation for products like TMS320C5510.
2.1 3X Series
This series is the very first floating point processor with 16.7 MHZ speed and
60-ns single cycle execution time. It can process 20 – 30 Million Instructions per Second.
This series processor uses two 1k x 32- bit single cycle dual-access RAM blocks and one
4K x 32-bit single cycle dual-access ROM block [6]. Since the majority of the instructions execute in a single cycle (after the pipeline is filled), the figure of 60 ns also indicates how long it takes to execute one instruction. Alternatively, we can say that the
7 device can execute 16.7 MIPS. This helps the processor to perform floating point addition and multiplication in single cycle.
The single cycle operation is achieved by the generation of internal clock with a period of 60 ns. Normally the actual signal produced by the external sources like oscillator or crystal has double the frequency of the internal device speed which is 33.3
MHZ and with the period of 30 ns. This frequency is then divided on-chip to generate the internal clock with a period of 60 ns. The above features allow the newer versions of the
TMS320C30 and other members of the ‘C3x generation to operate in higher frequencies range. This floating point DSP can be used to exploit delayed branch logic and it contains as many as three delay slots.
2.2 5X series
The TMS320C5x processors are the fastest and highest-performance processors among the TI 16-bit fixed point digital signal processors. This efficient application [6] is achieved through larger on-chip memory space, faster cycle time and systematic integration of more than one signal-processing functions. C5X is the most power efficient processors among the other TI’s digital signal processors. It can process 20 – 30 Million
Instructions per Second with the processing speed of 20-35 ns single cycle execution time. These processors make use of its Bit reversed / index addressing mode for Fast
8
Fourier Transform applications. The power efficiency of this processors is achieved by
the inclusion of special features like Power down mode, 8 Auxiliary registers, Single
cycle 16*16 bit parallel multiplier, 32 bit accumulator and 32 bit ALU.
It has some special peripheral features include Eight-level hardware stack, 11
context-switch registers to shadow the contents of strategic CPU-controlled registers
during interrupts, Full-duplex, Synchronous serial port, which directly interface to codec,
Concurrent external DMA performance, using holds and On-chip clock generator. The
major applications of these processors are Digital Cellular Base stations, PDA’s, Digital
Cordless Phones, Modems, Digital audio players, Digital still cameras, GPS receivers,
Wireless modems, Desktop video conferencing and digital audio and video compression
[6].
2.3 6X Series
The TMS320C6x family of digital signal processors (DSPs) is the first among
the other TI processors to employ VelociTI architecture [10], a new code-generation capability, and a large set of representative benchmarks. VelociTI architecture is a very long instruction word (VLIW) architecture. This architecture helps to push the performance of DSP to a new level. VelociTi, like other VLIWs, allows parallel fetch, decode, and execution of multiple instructions that compose the VLIW instruction word.
9
During execution, each instruction is performed on a single functional pair. TI considers this architecture as a Quantum leap in the performance of the TI digital signal processors.
This functions allow the processors to be used in multi-channel and multi-function applications. It can process 1600 Million Instructions per Second at a speed of 5 ns internal cycle time. This particular series of processors run at a frequency of 150 to 300
MHZ.
Some unique features like 0.25 micron 5 – layer metal, One Megabit On-chip
RAM, Four- channel DMA, SRAM, SB-SRAM, SDRAM interface, two Multichannel
TI/EI serial port and 352-pin BGA make these processors predominantly used in highest level of performance and high-precision applications.
The major applications of these processors are Medical, Industry applications, digital imaging, 3D graphics, speech recognition and voice-over packet, digital communications infrastructure, video and image processing, audio and medical imaging, instrumentation and automotive [6]. Texas Instruments provided deep integration and support for the C6X series in GNU compiler collection (GCC). GCC is a compiler system produced by the GNU project supporting various programming languages. The deep integration helped TI to provide Linux kernel to C6X. This culminated in C6X being a supported architecture in GCC release 4.7 on March 22, 2012.

CODE COMPOSER STUDIO VERSIONS AND COMPATABILITY ISSUES
3.1 CCS Version 3
This category "Code Composer Studio v3" includes the 3.0, 3.1, 3.2 and 3.3 releases. The v3.x included the IDE, debugger, Texas Instruments emulation drivers, simulators, compilers and DSP/BIOS. CCSv3.3 is the last release to support the
F24x/24xx family of microcontrollers. This version of CCS is compatible with Windows
2000 Service Pack 4, Windows XP Home Service Pack 1 & 2 and Windows XP Pro
Service Pack 1 & 2. They require 1-2 GB RAM and 500-2 GB free hard disc space. This version had all major chip support components for the DaVinci platform bundled in a single installer package. The major disadvantage is that they are compatible only with 32- bit version. Code Composer Studio 3.x (CCSv3) has limited support for Windows Vista and is not supported in Windows 7 (both 32 and 64 bit versions) [4].
3.2 CCS Version 4
Code Composer Studio V4 is based on the Eclipse open source software framework. They are mainly used for creating development tools. It includes the functionality of Eclipse software framework with advanced embedded debug capabilities.
11
CCSv4 comes bundled with various other components like DSP/BIOS, RTSC and 3P
Emulation drivers. A 'Typical Install' will install most of these and will use around 2 GB of space. A 'Custom Install' can be used to choose only the components of interest to reduce the final install size. 2GB of memory or more memory is highly recommended, it will run with 1GB but it will be slow. CCSv4 supports XP, Vista and Windows7.
3.3 CCS Version 5
This is the first CCS version with no modifications on the latest version of
Eclipse called ‘Stock’ eclipse and CDT. This features enable the users to integrate a wider range of 3rd party plugins and allows the upgradation of CCS open source components and also provide improvements in performance, usability and stability. This version automatically updated Eclipse and CDT for any latest updates which provides compatibility with Eclipse plugins also. CCS v5 is currently using Eclipse 3.6 and CDT
7.0. The most notable improvement is the speed and accuracy improvements on the indexer. It can automatically highlights syntax error in the source code as the source types and Console view highlights errors in red. Its multi-core improvements include execution of GEL commands in each CPU, loading programs and to run past initialization routines.
12
Some of the missing features in this version are no Grid mode support, no in
place editing for columns, AddExpression command does not support explicit expression
formatting and no bit field enumerations. Its major limitation is that the active project is
not selected as the user clicks on a project in the project view. CCS v5 supports both
windows and Linux operating systems.
3.4 CCS Version 6
Code Composer studio V6 is a major release and thus includes many new
features and enhancements. The new features allow the users to become familiar with the
Code composer studio easily. This version of Code Composer Studio is based on Eclipse
4.x. It requires 2 GB of memory space and disk space of 400MB. It runs on 1.0GHz x86 compatible processor and has the capability to run even on the Dual Core x86 compatible processor. This version does not require temporary space needed by the installer. Unlike other versions of code composer studio supports windows, Linux and Mac. It runs on
Windows XP SP3, Windows 7 and even Windows 8. Windows 10 is supported only by
CCS version 6.1.3. This particular version of CCS also supports MacOS.

TEST STUDIES ON THE 6713 DSK AND CODE COMPOSER VERSIONS
For experiments to study the compatibility issues of TMS320C6713 DSK with
the PCs, we used the Code composer studio version 5.3.0 and windows 10 operating
system. Earlier attempts to establish the connection between TMS320C6713 and Linux
had failed. In order to check the connection between the DSP kit and PC we used a
simple “Hello World” program and were able to see the output successfully on the
console. Then we decided to run Sine wave generation FIR digital filter implementation
programs.
4.1 Initial steps to create new project on the TMS320C6713 DSK
The steps provided below are used to create and run program in Code composer studio version 5.3.0. Assuming CCS is installed in C drive, given below is a summarized listing of steps and files required to make a project [9]:
1) Open CCS.
2) To create new project go to Project→ New.
3) Remember to select target TMS320C6713. Then chose output type as
“Executable”, family as “C6000”, variant as “TMS320C67XX” and
DSK6713. We used “Spectrum Digital DSK-EVM-eZdsp onboard USB
14
Emulator” as connection. Then we selected the option “Empty project
with main.c”. Go to Debug and select Connect. Now the target board is
connected to CCS.
4) Add source file (.c) code to the main.c file in the project.
5) Then add necessary library support files to the project.
6) Go to Project → Build All.
7) File → Load Program.
8) Debug → Run/ Resume.
9) Then the required output will appear on the oscilloscope and the
compiling status will appear on the Console.

4.2 Hello World Program
In order to check the connection between the DSK Kit and PCs with windows
10 operating system we ran and compiled the simple “Hello World” program. By using the procedure given in the previous section, we created a new CCS project in Code
Composer Studio version 5.3.0. Then included the program to display “Hello World” in the Console in the main.c file. Then by using the option Project Build All, we built the program and then performed debugging using Run Debug. This will create the output file with the format main.out. The .out is the executable file which contains the output from the build process is the file that can be loaded and executed on a target device. It can be directly loaded and debugged using CCS or can be converted to a different format, such as a hex format and programmed to the target using a hex programmer. Then, we loaded the main.out file using the option Run load and the sentence appeared on the Console window. This program confirms the compatibility and connection between the DSK Kit TMS3206713 and the PCs with Windows 10 operating system.
4.2.1 Hello World Program Code
The following is the listing of the “Hello World” program
/*
16
/* H E L L O.C /* */
#include
#define BUFSIZE 30 struct PARMS str = { 2934, 9432, 213, 9432, &str }; /* * ======main ======*/ void main() { #ifdef FILEIO int i; char scanStr[BUFSIZE]; char fileStr[BUFSIZE]; size_t readSize; FILE *fptr; #endif /* write a string to stdout */ puts("hello world!\n"); #ifdef FILEIO /* clear char arrays */ for (i = 0; i < BUFSIZE; i++) { scanStr[i] = 0 /* deliberate syntax error */ fileStr[i] = 0; } /* read a string from stdin */ scanf("%s", scanStr); /* open a file on the host and write char array */ fptr = fopen("file.txt", "w"); fprintf(fptr, "%s", scanStr);
17
fclose(fptr); /* open a file on the host and read char array */ fptr = fopen("file.txt", "r"); fseek(fptr, 0L, SEEK_SET); readSize = fread(fileStr, sizeof(char), BUFSIZE, fptr); printf("Read a %d byte char array: %s \n", readSize, fileStr); fclose(fptr); #endif }
The following is the output module of the program:

4.3 Sine Wave Generation
To check the compatibility for the sine wave generation experiment, we initially tried execution of the program in Linux machines but the program was not compatible with the usage of Code Composer Studio version 5.3.0 in the Windows Operating
System. After several attempts to find the correct Code Composer Studio version for
Windows, we identified CCS V5 Windows 10 Operating System to be a compatible system.
After setting up the circuit as shown, we connected the DSK to the PCs USB
port and DSK Kit headphone output port to the Oscilloscope, as shown in the schematic
in Figure 3. We created a new Code Composer Studio project with the name
Sine_Wave_Generator. We chose output type “Executable”, family “C6000”, variant
“TMS320C67XX” and “DSK6713”, and used the setting of “Spectrum Digital DSK-
EVM-eZdsp onboard USB Emulator” as connection. Then we selected the option “Empty
project with main.c” and added the header program “sine.h” which contains the function
definitions for the sine wave generator. Then we added the library files which were
needed for the program compilation. Then the program was successfully built and
debugged without any error. Even though the program was compiled without any issue
we were not able to see the sine wave in the Oscilloscope. By running the “Hello world”
program we confirmed that DSK Kit TMS320C6713 is compatible with Windows 10
19
operating system; however for the “Sine wave generation” program we could not see the
output in the oscilloscope.
The following is the block diagram for sine wave generation,

4.4 FIR Filter Implementation
We performed a similar procedure as the sine wave generation to create the FIR
filter implementation. Before creating the new project, we identified the process to set the
Sampling frequency for the DSK Kit TMS320C6713, from the manual provided for the
Kit. Using the assigned sampling frequency in the Filter design Matlab program, we
found the coefficients needed to perform Finite Impulse Response filter implementation.
Then the new CCS project was created with the necessary library support files and the
filter program written in C language was added. We used two different sources to
generate two sine waves operating in two different frequencies 2 KHz and 4 KHz and
both the signals were provided as input the DSK Kit. The filter program has been
compiled and debugged using the CCS Version 5.3.0 and the output of the program was
given to the DSK Kit. By connecting the Headphone Jack output of the DSK Kit to the
oscilloscope, we can see that DSK Kit filters and passes only the signals with the DSK
22
sampling frequency among the two different frequencies sine wave provided from two different sources.
The schematic of the FIR filter implementation is shown in Figure 3 below.

CONCLUSION
This project has focused on one of the very practical issues facing the operation
of the TMS320C6713 DSK on PCs running Windows versions 7 or higher. The primary
interfacing program is the Code Composer Studio (CCS), which in itself has various
versions, starting from version 3 to version 7. The compatibility issue study was done
systematically, utilizing all the latter versions of CCS one by one and testing the
compilation/execution of typical DSK programs such as signal generation and digital
filtering. In the case of signal generation, compilation was completed successfully, however, execution of the output file to display the sine wave on the oscilloscope did not go through successfully, even though the command message indicated completion of the program. In the case of the digital filtering, we were able to perform the compilation successfully similar to sine wave generation, but the execution of the output file to display the FIR filtered signal on the digital signal analyzer did not go through successfully.
The final conclusion made from the above analysis using different CCS versions is as follows: even though we were able to connect the DSK Kit 6713 successfully with the PCs operating on newer windows version and successfully compile/execute the DSK
28 programs, some compatibility issue due to some missing library files prevents us from displaying the required output on the digital signal analyzer.
