How to measure execution time with CYCLECOUNTER IAR

WebApr 10, 2024 · Since clock cycle time and clock rate are reciprocals, so, Execution time = CPU clock cycles / clock rate . The number of CPU clock cycles can be determined by, CPU clock cycles = (No. of instructions / Program ) x (Clock cycles / Instruction) = Instruction Count x CPI . Which gives, Execution time = Instruction Count x CPI x clock … WebLoop Timer - Type in the time and click 'Start' or press enter to start the online egg timer.
