(Section 1.2.1) Machine M runs at 3 GHz. When running program P, its CPI = 1.5.
(a) How many instructions will be executed during 1 second while running program P?
(b) While running program P, the mouse has to be polled 30 times per second. The polling routine requires executing 200 instructions with a CPI of 2. What is the overhead, that is, the fraction of time used in polling the mouse? Is it significant?
