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.
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.
- 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.
- 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.
- 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.
