In computer architecture, cycles per instruction (aka clock cycles per instruction, clocks per instruction, or CPI) is one aspect of a processor's performance: the average number of clock cycles per instruction for a program or program fragment. It is the multiplicative inverse of instructions per cycle.
An Interesting Question. • If two machines have the same ISA which of our quantities (e.g., clock rate, CPI, execution time, # of instructions, MIPS) will always be identical?

Last time we saw a MIPS single-cycle datapath and control unit. ? Today, we'll explore factors that contribute to a processor's execution time, and specifically at the performance of the Three Components of CPU Performance. Cycles Per Instruction. CPU time. X,P. = Instructions executed. P. * CPI. X,P. * Clock cycle time. X
cycle time (seconds per cycle). – clock rate (cycles per second). – CPI (cycles per instruction) a floating point intensive application might have a higher CPI. – MIPS (millions of instructions per second) this would be higher for a program using simple instructions. Performance. •. Performance is determined by execution time.
(30 * 6) + (50 * 4) + (20 * 3) = 440 cycles/100 instructions. Therefore, there are 4.4 Cycles per instruction. The CPU execution time on the benchmark is exactly 11 seconds. What is the ``native MIPS'' processor speed for the benchmark in millions of instructions per second? The formula for calculating MIPS is:
My best guess at interpreting your problem is that on average each instruction takes 3 cycles to complete. Because you were given the total number of cycles I'm not sure that the instruction count even matters. You have a 2Ghz machine so that is 2 * 10^9 cycles per second. This equates to each cycle
MIPS rating = –––––––––––––– = ––––––––– CPU time * 106 CPI * 106 The problems with MIPS rating as a performance measure: – difficult to compare computers with different instruction sets, – MIPS varies between programs on the same computer, – MIPS can vary inversely with performance!
For the single cycle MIPS, CPI = 1 but each instruction takes a different amount of time. Since no one has a crystal ball, one solution is to make the clock period as large as is needed for the execution of the slowest instruction. But this is not efficient.
