Abstract: Recent research results show that there is a high degree of code sharing between cores in multi-core architectures. In this paper we propose a proximity scheme for the instruction caches, a scheme in which the shared code blocks among the neighbouring L2 caches in tiled multi-core architectures are exploited to reduce the average cache miss penalty and the on-chip network traffic. We evaluate the proposed proximity scheme for instruction caches using a full-system simulator running an n-core tiled CMP. The experimental results reveal a significant execution time improvement of up to 91.4% for microbenchmarks whose instruction footprint does not fit in the private L2 cache. For real applications from the PARSEC benchmarks suite, the proposed scheme results in speedups of up to 8%.
