Fetch-Decode-Execute Cyclefetchdecodeexecutecyclefetch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

These three steps of the instruction execution cycle are, 1.Fetch: The processor copies the instruction data captured from the RAM. 2. Decode: Decoded captured data is transferred to the unit for execution. 3. Execute: Instruction is finally executed. The result is then regis...

Set Computer Central Processing Units (RISC CPUs) was designed to execute one instruction per cycle, five stages in total. Those stages are, Fetch, Decode, Execute, Memory, and Write. The simplicity of operations performed allows every instruction to be completed in one processor cycle. ...
