Q No.2

ET = CPI x IC x T = CPI x IC / f

ET = (4+7) x 65535/((1x106)

ET = 0.72 Sec

why frquency is 1x 10 ^ 6 i think yeeh 2 * 10^6 ay ga q k 2MHz queston main mention hai..

yes right

then Q No.2

ET = CPI x IC x T = CPI x IC / f

ET = (4+7) x 65535/((2x10^6)

ET = 0.36 Sec

Pay Attention to Definiton to understand the concept...

yes I think this is write

this assignment will cover which lectures?

Dear Students Don’t wait for solution post your problems here and discuss ... after discussion a perfect solution will come in a result. So, Start it now, replies here give your comments according to your knowledge and understandings....

ET = CPI x IC x T = CPI x IC / f

Where:

CPI: clocks per instruction

IC=instruction count

T=Time period of the clock.

F=Frequency of the clock
