Performance

Response Time: Time taken to do a particular task

Throughput: Total workdone per unit time

Clock Period: Duration of a clock cycle. e.g., 250 ps (picosecond)

Clock frequency: Number of clock cycles per second. e.g., 40 GHz or $40\times{10}^{9}\frac{cycles}{second}$

However,

Therefore,

Weighted Average CPI:

MIPS(Million Instructions Per Second):

Substituting CPU Time in the above equation,
