Abstract

Severe speed and dynamic range requirements are often imposed to the FFT algorithms necessary in modern communication systems. In this paper we discuss hand-optimised assembly codes for fixed-scaling and block-floatingpoint FFT algorithms providing 90% speed improvement with respect to the codes produced by TI C-development tools. Their use in a TMS320C6202-based system designed in our laboratory for range-Doppler applications is also described.
