Abstract

This paper presents a high performance FFT ASIP. The resulting programmable solution is scalable for the order of the FFT and capable of satisfying performance requirements of various OFDM wireless standards. The IEEE 802.15.3a Ultra Wideband OFDM - being the most time critical of these standards because of the computation of a 128-point FFT within 312.5 ns - has been the primary performance target of the scalable ASIP. The resulting ASIP adopts a vectorial Ultra-Long Instruction Word (ULIW) approach. The design decisions are evaluated with regards to processing speed, area and power dissipation.
