Document Summary
Execution time is equal to the number of instructions executed multiplied by the average time per instruction. Cpu clock cycles = instructions for a program * average clock cycles per instruction. Cpi: average number of clock cycles each instruction takes to execute. Architecture: levels of representation, technology trends, principle of. Suppose we have two implementations of the same instruction set architecture. Computer a has a clock cycle time of 250 ps and a cpi of 2. 0 for some program, and computer b has a clock cycle time of 500 ps and a cpi of 1. 2 for the same program. Cpu time = instruction count * cpi * clock cycle time. Cpu time = (instruction count * cpi) / clock rate. Energy on capacitive loading of each transistor. Suppose we developed a new, simpler processor that has 85% of the capacitive load of the more complex older processor.
