Beagle Board Omap 3530 BEAGLE BOARD OMAP 3530 AUTORA : TAMAR PÉREZ MIRANDA PONENT : FRANCESC ESCUDERO RESUME The Beagle Board is a low cost, fan-less and single board computer based on Texas Instruments' OMAP device family. OMAP means Open Multimedia Application Platform and it is a Texas Instruments proprietary microprocessor for multimedia applications. The aim of this work is to explore the capabilities of the Beagle Board and to spark interest in the device with universities. ABSTRACT As part of my 13-months internship in Texas Instruments working as University Support Engineer, I was assigned to lead a project which is intended to introduce the Beagle Board to universities. This project was meant to give academic institutions an idea of the wide capabilities of this extraordinary tool. As the current tendency in the components electronics fabrication world is to increase integration, a reduction in component size becomes more and more imperative without compromising the quality of components features and applications. That is why it is so attractive to use small technology, such as fan-less or usb-power, the technology which is used by Beagle Board. The Beagle Board is a low cost, fan-less and single board computer based on Texas Instruments' OMAP device family. OMAP means Open Multimedia Application Platform and it is a Texas Instruments proprietary microprocessor for multimedia applications. As university education puts a high value on working with the latest technology available on the market, Beagle Board offers colleges an opportunity to teach how to use state-of- the-art technology with a low cost tool. The aim of this work is to explore the capabilities of the Beagle Board and to spark interest in the device with universities.

INTRODUCTION This work is the result as a consequence of my 13-month internship in Texas Instruments working as University Support Engineer. I was assigned a project which is intended to introduce the Beagle Board to universities. The aim of this work is to explore the capabilities of the Beagle Board and to spark interest in the device with universities. In this introduction, it will be described where suits the Beagle Board in the world of System-on-Chip SOC and why is getting so popular in the university world. First of all, it will be explore what are the benefits and the needs of working with hybrid dual core SOCs. In this work we describe how well can suit Beagle Board in University projects due to the operating system choices that the board has, the embedded software component standards, and some special software framework that make the board working properly such as Codec Engine. For understanding better what is describe in the following chapters, in this part it is explain what have caused the trend to develop the hybrid System on Chip. The main problem is the wish of an extra high clock frequency and this implicates a lot of power that is not reached with the technology that exists in the market nowadays because they cannot tolerate the heat pollution that the high frequency emits. The problem is that the electrical power is too prohibitive for such higher frequencies and if the power consumption grows the heat dissipation becomes no practical for the computers. The next step was consider a multi-core board where are packed a lot of transistors however for consider all types of applications as Beagle Board does the best method is used a hybrid core. The hybrid core consists on a general purpose processor or GPP and a special purpose digital signal processor or DSP. The general purpose processors are high level operating systems oriented for handling a lot of I/O tasks however for voice, audio and video applications the digital signal processor is more efficient. Both processors are complementing each other because the DSP doesn´t support general purpose high-level OS applications efficiently. Beagle is used for applications that mix requirements combining GPP and DSP cores on a single chip. The board has an ARM general purpose processor and a high performance C64x+ DSP. The ARM processor is perfect for running common operating system like Linux, WinCE or Greenhills Integrity. The tasks consist on handle a high quantity of I/O and other - 1 - OMAP 3530 Beagle Board _________________________________________________________________________ functions such as graphical user interface or GUI. The DSP suits well for handling the digital signal processing functions that are necessary in the multimedia applications. In Chapter 2, it is shown a Beagle Board definition. Following with the explanation it will be describe in chapter 3 what consist the OMAP3530 technology on. Once studied the technology, in chapter 4, it will be study the hardware where I will provide my feedback about the strongest and the weakness of the Beagle regarding the hardware. The chapter 5 analyze the choice of the right operating systems for the Beagle. Basically, this consists of understanding the DSP scheduler and the use of Linux as a operating system that suits better for the general purpose processor. For the DSP which contains the Beagle (TMS320 family DSPs from TI) has been created the DSP/BIOS. The DSP/BIOS is a real time task scheduler, in other words, it could be also consider as a mini operating system that isn´t suitable for all use, however is ideal for the task that the DSP is designed to run. In the following software subchapters, it is described why the open source

  • Improving the Beaglebone Board with Embedded Ubuntu, Enhanced GPMC Driver and Python for Communication and Graphical Prototypes
    Final Master Thesis Improving the BeagleBone board with embedded Ubuntu, enhanced GPMC driver and Python for communication and graphical prototypes By RUBÉN GONZÁLEZ MUÑOZ Directed by MANUEL M. DOMINGUEZ PUMAR FINAL MASTER THESIS 30 ECTS, JULY 2015, ELECTRICAL AND ELECTRONICS ENGINEERING Abstract Abstract BeagleBone is a low price, small size Linux embedded microcomputer with a full set of I/O pins and processing power for real-time applications, also expandable with cape pluggable boards. The current work has been focused on improving the performance of this board. In this case, the BeagleBone comes with a pre-installed Angstrom OS and with a cape board using a particular software “overlay” and applications. Due to a lack of support, this pre-installed OS has been replaced by Ubuntu. As a consequence, the cape software and applications need to be adapted. Another necessity that emerges from the stated changes is to improve the communications through a GPMC interface. The depicted driver has been built for the new system as well as synchronous variants, also developed and tested. Finally, a set of applications in Python using the cape functionalities has been developed. Some extra graphical features have been included as example.

  • The 6502 Instruction Set
    6502asm user guide – prerelease version A PRE-RELEASE VERSION OF 6502ASM... IT MAY NOT WORK ENTIRELY CORRECTLYTHIS IS YET. If you discover errors, please report them to me! 6502asm v0.04 user guide page 1 6502asm user guide – prerelease version Introduction 6502asm is a simple assembler for 6502 code. It supports a variety of assembler commands to control output and extend the 6502 instruction set. The instruction set provided is the legal NMOS 6502 set, and the CMOS 65C02 instruction set according to the Western Design Center W65C02S datasheet (not the MOS 65CE02 variant). The NMOS “undocumented” instructions are not supported. The command syntax is: 6502asm <input file> <output file> Purpose 6502asm is part of the Amélie project. It was written in order to allow the BIOS code to be written and compiled without requiring the use of a BBC microcomputer (or emulator). While it is primarily intended for this purpose, it is flexible enough to be used for the assembly of 6502 code for other environments, such as the BBC micro (or compatible) or other 6502-based devices. 6502asm fits in with Amélie’s philosophy of “keep it simple”. 6502asm assembles in two passes, much as code is usually assembled under BBC BASIC. Currently, 6502asm does not support macros or conditional assembly, though these features are “in planning”. If you are used to Acorn systems, you may be pleased to know that 6502asm considers ‘&’ to mean “this is a hex number”, which is one of the main reasons I wrote this instead of using one of the many other 6502 assemblers available.
