Abstract :
A novel ASIC design of a 1024-point pipelined FFT Processor is introduced in this paper. This is a new FFT architecture based on the radix-2 algorithm and cordic algorithm. The solution adopted in the design is used to achieve a high-frequency FFT processor of which the frequency could reach as high as 330MHz. It also shows an advantage in saving up to fifty percent hardware resources over traditional FFT processor.
