摘要
针对基-2 FFT 处理算法,采用分块存储思想,将存储器、处理机数据交换网络模型进行优化。优化后的网络模型数据通路数仅为20,降低为原来的4%以下,且不随 FFT 计算点数增多而增加。整个设计在 Virtex 系统芯片 XCV800上实现。
Directed towards the radix-2 FFT algorithm, this paper introduces a new method, which can optimize the network module between the memory and the processing unit, by using the block memory. After network optimization, the link number is reduced to lower then 4% of normal design, and not increased with FFT points. This design is realized on XCV800.
