Exercise 3: 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 two possibilities Parameter Pipelined Version Non-Pipelined Version Clock Rate 500 MHZ 350 MHz CPI for ALU instructions 1 1 CPI for Control 2 1 CPI for Memory instructions 2.7 1 a) For a program with 20% ALU instructions, 10% control instructions and 70% memory instructions, Give a quantitative CPI average for each case, which design will be faster? b) For a program with 80% ALU instructions, 10% control instructions and 10% memory instructions. Give a quantitative CPI average for each case, which design will be faster? Question 1 (20 pts) Consider the following register set connected to a common ALU and having the following opcode table: RI R2 RA R 1 SEL OPR ALU OPR Operation 00000 Transfer A 00001 Increment A 00010 Add A + B 00101 Subtract-B 00110 Decrement SIUN MEN ASIA 01000 AND A and B B 01010 OR A and B Thendes 01100 XOR A and B 01110 Complement A 10000 Shift right 4 Figure 1 Register set with common ALU 11000 Shift left.
