| 摘 要： | 为解决目前高级综合方法在处理滑动窗口程序时存在的存储系统设计瓶颈问题,提出了参数化存储体系结构模型.采用三级存储层次,充分开发内层循环、外层循环的数据重用;采用寄存器平移策略,简化硬件设计.与相关工作相比,这种体系结构模型使用相对较少的存储资源,将程序执行速度提高了2.13倍~3.8倍,将执行频率由相关工作的69MHZ提升到了238.7MHZ.

| Abstract: | In order to deal with the memory bottleneck in high level synthesis tools for sliding-window operation, this paper presents a parameterized memory architecture for high level synthesis to automatically generate the hardware frames for all window processing applications. A three-level memory structure is designed to use inner-loop and outer-loop data completely, and at the same time shifted registers are used to make hardware design simpler. Compared with the related works, this approach can achieve a speedup of 2.13 to 3.8 times, and enhance the execution frequency from 69MHZ to 238.7MHZ. |
