📌 Overview

This assignment explores the gem5 simulator by running a Matrix–Matrix multiplication (MM) workload across different CPU models, CPU frequencies, and memory configurations.
The objective is to measure how performance (runtime, IPC, CPI, cache miss rates, DRAM bandwidth) varies under different architectural parameters.
