The processor in a computer is responsible for the beginning of the instruction cycle and the forthcoming steps of the instruction execution cycle. The first step for the processor is to check the next instruct
Pipelining is a well-known concept employed by CPUs for reducing the latency involved in the fetch-decode-execute cycle. 流水线是CPU所使用的一个众所周知的概念,它用于减少取指令-译码-执行周期中出现的延迟。 www.ibm.com 2. There are fours steps that nearly all CPUs use in their operation: fet...

The microprocessor repeats three steps—fetch, decode, and execute—over and over again to complete whatever task the computer is required to do. Particular areas of the microprocessor are designed to complete these three steps. The surface of a Pentium® microprocessor with the fetch,...
In the early days of computer hardware, Reduced Instruction 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 ...
