Using the previous example, your equation is 216 / 176 = 1.23 x 100 = 122.72. 15 Primary Cache, Miss Rate/Instruction = 7% L-2 Cache access time = 15ns. Divide the number of instructions by the execution time.
This is the number that makes your total comparable. For instance, if a computer with a CPU of 600 megahertz had a CPI of 3: 600/3 = 200; 200/1 million = 0.0002 MIPS. 16 0 obj 6 What is the difference between CPI and MIPS? {\displaystyle ={\frac {1.55\times 100000}{400\times 1000000}}={\frac {1.55}{4000}}=0.0003875\,{\text{sec}}=0.3875\,{\text{ms}}}.
Amdahl's law deals with the potential speedup of a program using multiple processors compared to a single processor. ( Then divide that time bythe number of times the loop executed. Required inputs for calculating MIPS are the Processors number of instructions per second, CPU processor speed (cycles per second), CPI (average clock cycles per instruction), and Execution time. 100 MIPS 1million instructions per second can be executed can be calculated as . {\displaystyle {\text{CPI}}={\frac {45000\times 1+32000\times 2+15000\times 2+8000\times 2}{100000}}={\frac {155000}{100000}}=1.55}, 400 The price change pertains to that year. 0000003317 00000 n
