SIC/XE Assembler

SIC/XE機器架構

  1. 記憶體 : 1 Mega bytes = 2 ^ 20
  2. 用來表示記憶體位址之位元數為 20 bits
  • 暫存器:(九種 每個24bits除浮點運算為48bits)

    • A (Accumulator) 累加器:算術運算
    • X (Index register) 索引暫存器:定址
    • L (Linkage register) 連結暫存器:跳到副程式JSUB,儲存返回位置
    • PC (Program counter) 程式計數器:儲存下一個要被執行的位置
    • SW (Status word) 狀態字組
    • B (Base register) 基底暫存器
    • S、T (一般用途)
    • F (Floating point accumulator) 浮點運算 48 bits

    Usage

將此專案clone下來後有兩個執行方法

方法1.

  • 利用Eclipse執行
  • 注意SIC.txt檔案路徑位置放置於src的上一層資料夾才能正確執行

方法2.

  • 利用終端機執行

    編譯java檔產出SICXE.class

    $ javac SIC.java 
    

    執行SIC應產出 SICXE_Final.txt

    $ java SICXE
    
  • 注意SICXE.txt檔案路徑位要與java放一起才能正確執行
