Question

Assume for a given program, 60% of the executed instructions
are of Class A, 10% are of Class B, and 30% are of Class C. Furthermore,
assume that an instruction in Class A requires 3 cycles, an instruction in
Class B requires 2 cycles, and an instruction in Class C requires 2 to
complete.

i. Compute the overall CPI for this program.
ii. Compute the clock rate of the CPU when the time it takes to
complete 20 instructions is 1.73 ???????????
