fetchdecodeexecutecyclefetch将pc指向的内存地址中的指令拷贝到指令寄存器中然后pc加4指令长度为4个字节就是说数据线是32bitsdecode从指令寄存器中提取操作数如果有的话和操作码execute如果需要将操作数从指令中指定的地址拷贝到寄存器中dataabort就是发生在这一步的接着根据操作码和操作数执行对应的操作了解了上面cpu...

王虾片 一条指令执行的过程可以拆分为 3 个阶段:取指令(Fetch)、指令译码(Decode)、执行指令(Execute)。取指令是把指令从内存加载到 CPU 的指令寄存器中;指令译码是将指令解析成具体的操作,比如操作哪些寄存器、数据或内存地址;执行指令就是实际去执行这些操作,比如进行算术逻辑操作、数据传输或者直接的地址跳转。前...

The CPU begins program execution by fetching them one at a time. Fetch, decode and execute cycle are the three steps that the CPU repetitively performs to complete one program instruction. The control unit decodes the machine instructions following the i
指令周期:在CPU处理流程中,“fetch”指“提取指令”阶段(Fetch-Decode-Execute Cycle)。 三、其他特定场景的译法 商业场景:表示“售得/卖得”,如“The painting fetched $1 million”译为“这幅画卖得100万美元”。 情感表达:口语中可引申为“迷住”,如“His speech fetched the audi...
