本研究旨在探索路由灵活性和硬件资源使用之间的权衡,最终减少我们的CGRA架构的资源使用,同时保持计算效率。摘要我们调查了基准DFG交换模块之间的连接使用情况,提出了几种减少连接的CGRA结构,并评估了它们的硬件成本、DFG的可路由性和基准DFG的计算吞吐量。我们发现,与水平加对角线连接的拓扑结构节省了约30%的资源使用,同时保持几乎相同的路由灵活性的全连接拓扑结构。
This research aims to explore the tradeoffs between routing flexibility and hardware resource usage, ultimately reducing the resource usage of our CGRA architecture while maintaining compute efficiency. we investigate statistics of connection usages among switch blocks for benchmark DFGs, propose several CGRA architecture with a reduced connection, and evaluate their hardware cost, routability of DFGs, and computational throughput for benchmarks. We found that the topology with horizontal plus diagonal connection saves about 30% of the resource usage while maintaining virtually the same routing flexibility as the full connectivity topology.
