Abstract

In this paper, we describe a processor architecture customized to Split radix FFT algorithm. The proposed architecture supports all FFT sizes, required by the LTE applications. The proposed design is aimed to reduce the area, latency, power and also to reduce the number of computational path in order to speed up FFT processor computation. The proposed low power 128 point split radix FFT architecture applies various periodicity properties of twiddle factors multiplier.We implement the processor in 128-point MDC architecture with split radix algorithm. The processor has been synthesized on a Xilinx ISE 10.1design technology and both energy-efficiency and performance have been evaluated.
