The design team for a simple, single-issue processor is choosing between a pipelined or non-pipelined implementation. Here are some design parameters for the twopossibilities:

Parameter Pipelined Version Non-Pipelined Version

Clock Rate	500MHz	350 MHz
CPI for ALU instructions	1	1
CPI for Control instructions	2	1
CPI for Memory instructions	2.7	1

(a) For a program with 20% ALU instructions, 10% control instructions and 70% memory instructions, which design will be faster? Give a quantitative CPI average for each case.

(b) For a program with 80% ALU instructions, 10% control instructions and 10% memory instructions, which design will be faster? Give a quantitative CPI average for each case.
