摘要

While multi-core design brings opportunity for more performance and power efficiency, there are performance challenges as the number of cores increase. This increase in performance can only be harnessed when issues like memory speed bottleneck and decreasing average cache size per core are overcome. The target applications must be known to maximize the performance improvements through increasing parallelism and cache hit rates. Also applications require highly diverse cache configurations for optimal energy consumption in the memory hierarchy to support their implementation. In this paper various cache organizations for multi-core processors are simulated and their performance and energy tradeoff are studied for emerging workloads. Finally, the trend in performance and energy consumption for the optimized cache configurations with increasing number of cores is analyzed.
