On-Chip Cache Procedure and Device for Efficient CPU and GPU Access Request Arbitration

Abstract

This research paper presents a novel on-chip cache procedure and device that effectively handles access requests from both CPUs and GPUs. The proposed procedure involves classification caching based on the access request type, arbitrating different types of access requests for caching, and optimizing access time for CPU requests through cache while bypassing cache for GPU requests. The device includes CPU and GPU request queues, a moderator, and cache performance elements. By considering the distinct access characteristics of CPUs and GPUs simultaneously, this approach offers high performance, simple hardware implementation, and minimal cost
