These results are more or less ‘expected’ because a) the Mitsubishi device is a 16-bit microcontroller compared to the other two devices which are 32-bit microcontrollers; b) operating frequency is a big factor in performance measurements; c) after normalizing for operating frequency, the Infineon device is still approximately 10% faster than the NEC device, this is most likely related to the former’s enhanced ability to perform signal processing. EEMBC Benchmark Results Simluation Benchmark Scores Infineon TriCore/TC1M IBM ppc405d4v6 ARM1026EJ-S SuperH SH4-202 SuperH SH5-103 0 0.10.20.30.40.50.60.7 Automarks per MHz Similar to the explanation on the previous slide, this chart compares 5 processor architectures using EEMBC’s Automarks. One of the significant differences on this chart is that these scores are all based on running the benchmarks using simulators for these processors and all scores are normalized to 1MHz. Without going into the specific details for each processor, it’s important to note that the ARM and SuperH devices support hardware floating-point units that will help boost their performance on several of the Automotive/Industrial benchmarks..

The processor’s computation units provide the numeric processing power for performing DSP algorithms, performing operations on both fixed-point and floating-point numbers. Each computation unit executes instructions in a single cycle. The processor contains three computation units: • An arithmetic/logic unit (ALU) Performs a standard set of arithmetic and logic operations in both fixed-point and floating-point formats. • A multiplier Performs floating-point and fixed-point multiplication as well as fixed-point dual multiply/add or multiply/subtract operations. •A shifter Performs logical and arithmetic shifts, bit manipulation, field deposit and extraction operations on 32-bit operands and can derive exponents as well.

The output from any computation unit can be input to any computation unit on the next cycle. The computation units store input operands and results locally in a ten-port register file. The Register File is accessible to the processor’s pro- gram memory data (PMD) bus and its data memory data (DMD) bus. Both of these buses transfer data between the computation units and internal memory, external memory, or other parts of the processor.

    Introduction: Data Transfer and Manipulation Most computer instructions can be classified into three categories: 1) Data transfer, 2) Data manipulation, 3) Program control instructions » Data transfer instruction cause transfer of data from one location to another » Data manipulation performs arithmatic, logic and shift operations. » Program control instructions provide decision making capabilities and change the path taken by the program when executed in computer. Data Transfer Instruction Typical Data Transfer Instruction : LD » Load : transfer from memory to a processor register, usually an AC (memory read) ST » Store : transfer from a processor register into memory (memory write) MOV » Move : transfer from one register to another register XCH » Exchange : swap information between two registers or a register and a memory word IN/OUT » Input/Output : transfer data among processor registers and input/output device PUSH/POP » Push/Pop : transfer data between processor registers and a memory stack MODE ASSEMBLY REGISTER TRANSFER CONVENTION Direct Address LD ADR ACM[ADR] Indirect Address LD @ADR ACM[M[ADR]] Relative Address LD $ADR ACM[PC+ADR] Immediate Address LD #NBR ACNBR Index Address LD ADR(X) ACM[ADR+XR] Register LD R1 ACR1 Register Indirect LD (R1) ACM[R1] Autoincrement LD (R1)+ ACM[R1], R1R1+1 8 Addressing Mode for the LOAD Instruction Data Manipulation Instruction 1) Arithmetic, 2) Logical and bit manipulation, 3) Shift Instruction Arithmetic Instructions : NAME MNEMONIC Increment INC Decrement DEC Add ADD Subtract SUB Multiply

  • Bit Manipulation
    jhtp_appK_BitManipulation.fm Page 1 Tuesday, April 11, 2017 12:28 PM K Bit Manipulation K.1 Introduction This appendix presents an extensive discussion of bit-manipulation operators, followed by a discussion of class BitSet, which enables the creation of bit-array-like objects for setting and getting individual bit values. Java provides extensive bit-manipulation capabilities for programmers who need to get down to the “bits-and-bytes” level. Operating systems, test equipment software, networking software and many other kinds of software require that the programmer communicate “directly with the hardware.” We now discuss Java’s bit- manipulation capabilities and bitwise operators. K.2 Bit Manipulation and the Bitwise Operators Computers represent all data internally as sequences of bits. Each bit can assume the value 0 or the value 1. On most systems, a sequence of eight bits forms a byte—the standard storage unit for a variable of type byte. Other types are stored in larger numbers of bytes. The bitwise operators can manipulate the bits of integral operands (i.e., operations of type byte, char, short, int and long), but not floating-point operands. The discussions of bit- wise operators in this section show the binary representations of the integer operands. The bitwise operators are bitwise AND (&), bitwise inclusive OR (|), bitwise exclu- sive OR (^), left shift (<<), signed right shift (>>), unsigned right shift (>>>) and bitwise complement (~). The bitwise AND, bitwise inclusive OR and bitwise exclusive OR oper- ators compare their two operands bit by bit. The bitwise AND operator sets each bit in the result to 1 if and only if the corresponding bit in both operands is 1.

  • On the Standardization of Fundamental Bit Manipulation Utilities
    Document number: P0237R0 Date: 2016–02–12 Project: ISO JTC1/SC22/WG21: Programming Language C++ Audience: Library Evolution Working Group, SG14 Reply to: Vincent Reverdy ([email protected]) On the standardization of fundamental bit manipulation utilities Vincent Reverdy1 and Robert J. Brunner1 1Department of Astronomy, University of Illinois at Urbana-Champaign, 1002 W. Green St., Urbana, IL 61801 Abstract We discuss the addition to the standard library of class templates to ease the manipulation of bits in C++. This includes a bit_value class emulating a single bit, a bit_reference em- ulating a reference to a bit, a bit_pointer emulating a pointer to a bit, and a bit_iterator to iterate on bits. These tools would provide a solid foundation of algorithms operating on bits and would facilitate the use of unsigned integers as bit containers. Contents 1 Introduction2 2 Motivation2 3 Impact on the standard3 4 Design decisions4 5 Technical specications 16 6 Alternative technical specications 26 7 Discussion and open questions 29 8 Acknowledgements 30 9 References 31 1 1 Introduction This proposal introduces a class template std::bit_reference that is designed to emulate a ref- erence to a bit. It is inspired by the existing nested classes of the standard library: std::bitset:: reference and std::vector<bool>::reference, but this new class is made available to C++ developers as a basic tool to construct their own bit containers and algorithms. It is supple- mented by a std::bit_value class to deal with non-referenced and temporary bit values. To provide a complete and consistent set of tools, we also introduce a std::bit_pointer in order to emulate the behaviour of a pointer to a bit.
