MIPS/RISC Features

- 指令集的限制

  • 指令长度必须都是32位, 不可能把一个32位常数放进单个指令

  • 指令操作必须适合流水线

  • 三操作数的指令

  • 32个通用寄存器

  • 寄存器零

  • 没有条件码

    - 寻址和访存

  • 访问内存只能通过简单的寄存器加载和存储

  • 只有一种数据寻址方式

  • 字节地址指令 - 符号扩展和零扩展

  • load/store必须对齐

  • 跳转指令

    - 没有的特性

  • 没有字节或半字数据的运算

  • 没有对堆栈的特殊支持

  • 最少的子程序支持

  • 最少的中断处理

  • 最少的异常处理
