Question

A 2 ns clock cycle processors consumes 4 cycles for ALU operations, 3 cycles for branches and 5 cycles for memory operations. The relative frequencies of these operations are 45%, 15% and 40% respectively.

 

 

Q.16 What is the average instruction execution time (in nano seconds)?

 

Q.17 What is performance in MIPS?

 

Q.18 If the program contains 10 instructions. What is the program execution time (in sec)?

Answer 1

Performance in MIPS is how many instructions you can execute in 1 second

8.5 ns time will take for 1 instruction to get executed. 

Accordingly 117.6 M instructions can execute per second.
