HDL 기말 프로젝트 Simple Cpu

개발 환경

  • modelsim (for simulation)
  • Fpga
    • Board: Spartan-3AN Starter Kit
    • Software: Xilinx_ISE_13.3

      Architecture

  • Component
    • CPU
    • Keyboard: ps2_rx module
    • VGA Controller

      Description

      각자 설계한 CPU + VGA controller + keyboard 를 이용하여 다음과 같이 실습 시험을 치룸

  • 실습 시험 당일 주어지는 2개의 8-bit unsigned number 를 임의 레지스터로 로딩하 고 모니터 화면에 하나씩 출력되도록 myrom 용 프로그램(기계어)를 수정해 .coe 파일로 저 장
  • ISE 합성 후 configuration
  • 키보드의 키(A: addition, X: xor, N: nand, R: shift right, L: shift left)를 랜덤하게 누를 때마다 그 number 들에 대해 연산을 수행해 그 결 과를 화면에 출력
    • addition 시 carry 는 무시할 것
    • shift 연산은 첫번째 숫자에만 적용

      myrom.coe 파일(기계어 프로그래밍)

      프로젝트 중 가장 어려웠더 부분이 myrom을 모듈(.v파일)로서 구현하는게 아닌 순수 기계어(coe파일)로 작성해야 하는것이 난이도가 있었습니다.
      각 모듈을 참고하며 프로그램의 흐름을 만든뒤 적절한 조건과 분기를 통해 기능을 구현하였습니다.
