Unformatted text preview: t is found that in a typical execution of the Spice circuit simulation program 75% of all instructions do f loating point operations. If we add a f loating point coprocessor that is three times faster than the old one to the system, what is the rate of speed up? (10%) 8. Consider two different implementations P1 and P2, of the same instruction set. There are several classes of instruction in the instruction set. P1 has a clock rate 4GHz, P2 has a clock rate 6 GHz. The average number of cycles for each instruction class for P1 and P2 is as follows:
Class A B C D CPI on P1 1 2 3 4 CPI on P2 2 2 4 4 Program X's instructions 40% 10% 40% 10% As the table shows, how much faster is P2 than P1 in executing X? (10%) 9. Sh...
