MultiCycle Processor Design points
Detailed Cycle Counting with Varying Latencies: A multicycle processor executes different types of instructions with varying cycle counts as follows:
ALU operations eg add, sub: cycles
Load word LW: cycles
Store word SW: cycles
Branch instructions eg BEQ: cycles
Given a program with the following instruction mix:
ALU operations
load instructions
store instructions
branch instructions
If the program consists of instructions, calculate the total number of cycles required to execute the program and determine the average CPI.
Impact of Hazard Mitigation Techniques: In a multicycle processor, assume the following base cycle counts for different types of instructions:
ALU operations: cycles
Load LW: cycles
Store SW: cycles
Branch BEQ: cycles
Introducing hazard detection and forwarding techniques adds extra cycle to ALU and branch instructions but eliminates cycle from load instructions. Given the same instruction mix as above, calculate the new total number of cycles required to execute the instructions and the new average CPI.
