1 Determine whether the following questions are True or Fals

1. Determine whether the following questions are True or False. (A wrong answer leads to “-1\" point not \"O point) (5 points) l) If two microprocessors have a same ISA (Instruction Set Architecture), the IPC (Instruction Per Cycle) for same program should be same. (1 point) 2) when the clock cycle time is 100 ps, the clock frequency is 10 G (1 point) ) Benchmark is one program for evaluating performance. (1 point) 4) In case of multi-cycle implementation, instructions are parallel executed for better performance compared to single-cycle implementation. (1 point) CPI for single-cycle implementation is always 1. (1 point) 5)

Solution

1) No becuase number of cycles are different from different instructions .Different instructions take different amounts of timethat means no of cycles per second

2)yes ,f=1/T

f=1/100ps

=10*10^9

=10GHZ

3) yes,benchmark is one program for evaluating performance.measuring,comparing to competition ,identifying the opportunities for improvement are the main for benchmarking

4)yes instructions are parallel executed for better performance

5) CPI for single cycle implementation is always 1 for better performance
