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.
