Question 1. Assume that the MIPS stages have these latencies (in ps):
Execute
Register
Read
Register
Write
(EX)
Instruction
Memory
(IF)
50
(ID)
20
30
Suppose that we modified the pipelined processor described in
Question 1 such that all data memory reads and memory writes were split
into two separate stages of 50 ps. each.
a) Would the overall throughput increase or decrease in the
modified architecture?
b) What is the cycle time of modified pipelined processor?
c) What would the resulting speedup be?
