# Cache Remapping Project - README

## Introduction
This repository contains the codebase and report for the CS204 project aimed at understanding cache misses and proposing a solution to increase Instruction Per Cycle. The project focuses on implementing novel cache remapping strategies to improve cache performance.

## Project Objective
The objective of this project is to reduce conflict misses in the cache by implementing different cache remapping strategies and evaluating their impact on cache performance.

## Versions and Results

### Version 1
- Implemented a cache remapping strategy based on access frequency of cache sets.
- Reserved a least frequently accessed cache set for each hot set.
- Increased IPC by 0.05% from the original result.

### Version 2
- Increased the number of reserved cold sets for each hot set.
- Introduced read redirection to reduce frequent main memory accesses.
- Increased IPC by 0.23% from the original result.

### Version 3
- Rectified logical flaws in determining hot and cold sets.
- Optimized read redirection by removing unnecessary sets.
- Increased IPC by 1.2% from the original result.

## How to Run Instructions
1. Clone the repository:

```
git clone https://github.com/kushrm2803/ChampSim.git
```

2. Open in UNIX based system and navigate to the directory containing the codebase.

3. For granting permissions, run for both build_champsim.sh and run_champsim.sh

```
chmod +x script.sh example : chmod +x build_champsim.sh
```

```
sed -i -e 's/\r$/\n/' script.sh example: sed -i -e 's/\r$/\n/' build_champsim.sh
```

3. Build the ChampSim simulator:

```
./build_champsim.sh bimodal no no no no lru 1
```

4. Run the ChampSim simulator with the desired configuration:

```
./run_champsim.sh bimodal-no-no-no-no-lru-1core 1 10
```

Replace `` with the name of the trace file you want to simulate.
