Given: Computer A has an overall CPI of 1.3 and can be run at a clock rate of 600 MHz. Computer B has a CPI of 2.5 and can be run at a clock rate of 500 MHz. We have to find the number of instructions the program would need to have when compiled for Computer B in order for the two computers to have exactly the same execution time for this program.
Part 1: How many instructions would the program need to have when compiled for Computer B in order for the two computers to have exactly the same execution time for this program?
a) 41600 instructions
b) 65000 instructions
c) 50000 instructions
d) 42000 instructions
e) 162500 instructions
f) 125000 instructions
g) 240000 instructions
h) 80000 instructions
Answer 1:
(Note: Indicate ONLY the LETTER corresponding to your choice)
Part 2: Calculate the MIPS ratings for Computer A and Computer B, given the condition in Partial Credit 1)
a) A:MIPS=600, B:MIPS=750
b) A:MIPS=600000, B:MIPS=750000
c) A:MIPS=600000000, B:MIPS=750000000
d) A:MIPS=461000, B:MIPS=300000
e) A:MIPS=461, B:MIPS=200
f) A:MIPS=461000000, B:MIPS=300000000
