Abstract
We present a memory-efficient NoC system for OpenCL many-core platforms. By offloading the OpenCL kernel programs into the many-core processor, we reveal that the memory contention overheads have dramatically increased with the scaling of the system, resulting to the poor performance scalability of the many-core system. We explore a memory-efficient NoC system design which includes a mesh network, a hybrid network interface for packet composition and decomposition, and a memory controller with access scheduling capability. Our experimental results show that a simple memory access scheduling and caching approach can easily boost the performance of the NoC and memory system up to 20 percent by eliminating the memory controller contention problem.
