🧠 Computer Architecture Assignments

This repository contains two computer architecture assignments focused on advanced processor simulation and multimedia SIMD emulation:

1. Tomasulo Algorithm Simulation using DLXview
2. Emulation of MIPS MSA (Multimedia SIMD Architecture) using Docker, QEMU, and Inline Assembly

🔧 Assignment 1: Tomasulo Algorithm with DLXview

This assignment explores dynamic instruction scheduling using the Tomasulo algorithm on a DLX-like processor simulator.

Part 1: Resource Optimization

• The goal is to determine the minimum number of reservation stations and buffers needed so that the instruction pipeline never stalls.
• A small looped program is analyzed using the DLXview tool.
• Students must configure DLXview with specific latencies and simulate execution to identify the optimal configuration.

Part 2: Neural Network Implementation

• A small feedforward neural network with two perceptron neurons and five inputs is implemented in DLX assembly.
• The network includes weighted sums, bias addition, and threshold activation.
• The final implementation is submitted as two DLX files.

🖥️ Assignment 2: MIPS MSA Emulation with QEMU & Docker

This assignment focuses on emulating MIPS64 SIMD instructions using inline assembly and the MIPS MSA instruction set.

Environment Setup

• Students use Docker to run a Linux environment on Windows.
• The MIPS64 cross-compiler and QEMU emulator are installed inside the Docker container.

Task Overview

• Two C programs are provided (ex13.c and ex14.c) that operate on image and vector data.
• Each program is implemented in:
  • A scalar version
  • A SIMD version using MIPS MSA instructions

Objectives

• Learn to use inline assembly with the MIPS MSA instruction set.
• Understand how SIMD instructions can replace scalar loops.
• Validate correctness by comparing outputs of scalar and SIMD versions.
• Complete the missing SIMD implementation in one of the exercises.

Deliverables

• Completed source files for all program versions.
• Execution output files for validation.
• A brief report (PDF) with screenshots and a summary of findings.
