چکیده انگلیسی

We demonstrate that the proposed cache architecture successfully alleviates the memory bandwidth bottleneck and that the novel replacement policy can provide a good performance increase for small cache sizes and may work well as a complimentary cache along side a direct mapped cache. The evaluation further shows that scaling the number of traversal units with a cache provides an increase in performance over all scenes. We also demonstrate the energy and bandwidth efficiency of the proposed platform in comparison to a CPU and a GPU platform.
