operates like a bne (branch-if-not-equal) instruction. In other words, in your implementations you will assume that the beq jumps to the branch address if and jumps to PC+4 otherwise, i.e.,. (Note that a real beq instruction would operate in the opposite fashion, that is, it will j...

三、MIPS简介 1、处理器的缩写 ① Million Instruction Per Second,泛指每秒能执行百万条指令的处理器 ② Microprocessor without Interlocking Pipeline Stage, 一种无内锁的流水线微处理器 2、MIPS公司 3.2 计算机硬件的操作指令 一、指令的基本格式 指令格式,是指令用二进制代码表示的结构形式,通常有 操作码字段和...
因此,只要采用 RAM 来实现 InstructionMemory 模块,就可以非常方便地载入不同的汇编代码进行调试。当然,这个函数也能用于向 DataMemory 载入数据。这样,使用不同的汇编代码和数据仿真就变得非常方便。采用RAM 实现 InstructionMemory 模块还有一个好处,就是在硬件调试时,可以配合串口,随时载入不同的汇编指令,而无需重新...
