摘要: 存储系统是通用处理器在处理流应用时的瓶颈。该文基于FT64流处理器体系结构,提出一种面向流应用的流寄存器文件结构设计方法和数据传输机制,分析它在FT64中的作用。通过采用大容量、高带宽、虚拟多端口的存储器,将大部分流数据存取操作限制在寄存器文件这一层次,减少了主存压力。实验结果表明,该结构能很好地适应流应用需求。

Abstract: The memory system is the performance bottleneck while general processor handles stream applications. Based on the FT64 stream architecture, this paper presents a structure design method and data transfer mechanism of the stream register file which is oriented to stream application, and analyzes the effect on FT64. This structure with the adoption of big capacity, high bandwidth and multiple virtual ports can limit most of the stream data access operation at the register file level, greatly decrease the pressure of the main memory. Experimental result shows this structure meets the demand of stream applications.

Key words: stream register file, stream processor, FT64 processor, computing kernel, memory
