介绍了一种单片512点FFT处理器。该处理器基于缓存内存架构(CMA),具有节省资源的多数据路径基数2/sup 2/计算单元。两级CMA,包括一对单端口sram,也被引入以加快二维fft的执行时间。利用上述技术,我们设计了一个FFT处理器核心,该核心采用CMOS 0.35 /spl mu/m三层金属工艺,在2.8 /spl倍/ 2.8 mm/sup 2/的面积内集成了552,000个晶体管。该处理器可以执行512点,36位复杂的定点数据格式,一维FFT的速度为23.2 /spl mu/sec,二维FFT的速度仅为23.8 msec,操作频率为133 MHz。
A single-chip 512-point FFT processor is presented. This processor is based on the cached-memory architecture (CMA) with the resource saving multi-datapath radix-2/sup 2/ computation element. The 2-stage CMA, including a pair of single-port SRAMs, is also introduced to speedup the execution time of the 2-dimensional FFTs. Using the above techniques, we have designed an FFT processor core which integrates 552,000 transistors within an area of 2.8 /spl times/ 2.8 mm/sup 2/ with CMOS 0.35 /spl mu/m triple-layer-metal process. This processor can execute a 512-point, 36-bit-complex fixed-point data format, 1-dimensional FFT in 23.2 /spl mu/sec and a 2-dimensional one in only 23.8 msec at 133 MHz operation.
