  • A virtual instruction set architecture (V-ISA) implemented via a processor-specific software translation layer can provide great flexibility to processor designers. Recent examples such as Crusoe and DAISY, however, have used existing hardware instruction sets as virtual ISAs, which complicates translation and optimization. In fact, there has been little research on specific designs for a virtual ISA for processors. This paper proposes a novel virtual ISA (LLVA) and a translation strategy for implementing it on arbitrary hardware.

  • High-level languages, such as C, C++, and Java, are more like natural languages and thus make programs easier to read and write. Low-level languages are closer to the machine and there is a one-to-many relationship between high-level languages and low-level languages, where language translators such as compilers and interpreters convert each high-level instruction into many low-level instructions. The native language of a particular machine is a low-level language known as machine language and is coded in ones and zeros.

  • In this chapter, we will introduce you to the tools you need in order to begin using MATLAB effectively. These include the following: some relevant information on computer platforms and software; installation protocols; how to launch MATLAB, enter commands and use online help; a roster of MATLAB’s various windows; and finally, how to exit the program. We know you are anxious to get started using MATLAB, so we will keep this chapter brief. After you complete it, you can go immediately to Chapter 2 to find concrete and simple instructions for using MATLAB to do mathematics.

  • The purpose of this design problem is building up the data path and constructing a simple version of 32-bit MIPS Single-Cycle CPU. The CPU instructions to be implemented are the memory-reference instruction LW & SW, the arithmetic –logical XORI, ADD, SUB, SLT, and BNE, J, JR function. The system takes PC address as an input and converts it into instruction to implement the functions. The lab report includes the data path single cycle of MIPS overview, the simulation and Verilog code using the Quartus and ModelSim program....

  • Question 1. What is a computer? A computer may be defined as a machine which accepts data from  an input device, processes it by performing arithmetical and  logic operations in accordance with a program of instructions  and returns the results through an output unit. A computer is basically an electronic machine operating on  current.

  • Our goal in writing this book is to expose the inner workings of the modern digital computer at a level that demystifies what goes on inside the machine. The only prerequisite to Principles of Computer Architecture is a working knowledge of a high-level programming language. The breadth of material has been chosen to cover topics normally found in a first course in computer architecture or computer organization. The breadth and depth of coverage have been steered to also place the beginning student on a solid track for continuing studies in computer related disciplines....

  • The AVR core combines a rich instruction set with 32 general purpose working registers. All the 32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent registers to be accessed in one single instruction executed in one clock cycle. The resulting architecture is more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers.
