Modern Computer Architecture and Organization

By: Jim Ledin

Overview of this book

Are you a software developer, systems designer, or computer architecture student looking for a methodical introduction to digital device architectures but overwhelmed by their complexity? This book will help you to learn how modern computer systems work, from the lowest level of transistor switching to the macro view of collaborating multiprocessor servers. You'll gain unique insights into the internal behavior of processors that execute the code developed in high-level languages and enable you to design more efficient and scalable software systems. The book will teach you the fundamentals of computer systems including transistors, logic gates, sequential logic, and instruction operations. You will learn details of modern processor architectures and instruction sets including x86, x64, ARM, and RISC-V. You will see how to implement a RISC-V processor in a low-cost FPGA board and how to write a quantum computing program and run it on an actual quantum computer. By the end of this book, you will have a thorough understanding of modern processor and computer architectures and the future directions these architectures are likely to take.

RISC-V assembly language

The following RISC-V assembly language example is a complete application that runs on a RISC-V processor:

.section .text
.global main
main:
    # Reserve stack space and save the return address
    addi    sp, sp, -16
    sd      ra, 0(sp)
    # Print the message using the C library puts function
1:  auipc   a0, %pcrel_hi(msg)
    addi    a0, a0, %pcrel_lo(1b)
    jal     ra, puts
    # Restore the return address and sp, and return to caller
    ld      ra, 0(sp)
    addi    sp, sp, 16
    jalr    zero, ra, 0
.section .rodata
msg:
    .asciz "Hello, Computer Architect!\n"

This program prints the following message in a console window and then exits:

Hello, Computer Architect!

The following are some points of interest within the assembly code:

  • The %pcrel_hi and %pcrel_lo directives select the high 20 bits (%pcrel_hi) or low 12 bits (%pcrel_lo) of the PC-relative address of the label provided as an argument. The combination of the...
