Facing the varying demand fix digital signal processing applications, the existing solution including general-purpose processor, DSP, ASIC and FPGA can not meet the requirements of cost, power consumption, performance and flexibility. To solve these problems, this study combined the technologies of stream processing, and reconfigurable platform, and proposed A Multi-Granularity Reconfigurable DSP based on Stream Architecture Template (MGR-SAT). MGR-SAT uses stream processing techniques to decouple the data on operations and memory access, offering a large-scale data parallel. Meanwhile it uses the reconfigurable technology to accelerate the key algorithms and uses the platform technology to provide fast reconfiguration as well. The experimental results show that MCR-SAT has a great potential to deliver high performance.%面对需求各异的数字信号处理应用,当前主流的通用处理器、DSP、ASIC和FPGA不能同时满足各应用在成本、功耗、性能、灵活性方面的要求.针对这些问题,结合流处理技术、可重构技术和平台技术,提出一种基于流模板的多粒度可重构数字信号处理器MGR-SAT.MGR-SAT利用流处理技术来解耦合数据运算与访存,提供多种粒度的大规模数据并行,同时利用可重构技术对关键算法进行加速处理,而平台技术则为系统提供快速的重构能力.实验结果显示,MGR-SAT在数字信号处理领域具有极大潜力.
