1. Consider the two computers (MI and M2] and program (PI), and additional measures are made. Program Time on MI Time on M2 PI 20 seconds 1.5 seconds 1.5 seconds Frogram Instructions executed on MI Instructions executed on MZ PI 5 x 1049 6 x 10^9 the instruction execution rate (instructions per second) for each computer when running program PL [2 pts] 2. Consider three different processors P1, P2, and P3 executing the same instruction set. Processor Clock Rate Clock cycles Per Instruction 3 GHz 1.5 25 GHz 1.0 P3 4 GHz 2.2 P2 [4 pts] a. Which processor has the highest performance expressed in instructions per second? b. If the processor Pl executes a program in 10 seconds, find the number of cycles and the number of instructions. Consider only Pl. 3. Consider the instructions that can be divided into four classes according to the CM (class A, B, C, and D). A processor Pl has a clock rate of 2 GHz. The average number of cycles for each instruction class for Pl is as follows: Class CPI on PI AI I B 2 Given a program with a dynamic instruction count of 10 x 10 instructions divided into classes as follows 10% class A. 20% class B, 50% class C, and 20% class D. [4 pts] a. Find the clock cycles required. b. Find the execution time of instructions
