Computer Performance Evaluation: Cycles Per Instruction (CPI)
{"Image DocumentName": "Computer Performance Evaluation: Cycles Per Instruction (CPI)", "Image ImageDescription": "Most computers run synchronously utilizing a CPU clock running at a constant clock rate: where: Clock rate = 1 / clock cycle. A computer machine instruction is comprised of a number of elementary or micro operations which vary in number and complexity depending on the instruction and the exact CPU organization and implementation. A micro operation is an elementary hardware operation that can be performed during one CPU clock cycle. This corresponds to one micro-instruction in microprogrammed CPUs. Examples: register operations: shift, load, clear, increment, ALU operations: add , subtract, etc. Thus a single machine instruction may take one or more cycles to complete termed as the Cycles Per Instruction (CPI).
