A NEW ALGORITHM OF FFT ON TMS 32010
Geok Soon Hong · Computer Applications and Software · 1989
The TMS32010 is a 5 MIPS processor that is most widely used IC for DSPapplications.It is distinguished from general-purpose microprocessors in that it containsan on chip multiplier,computes a pipelined running sum of products,and performsdata scaling,memory shifts,and pointer incrementation in parallel with other opera-tions.This is a new 32 bit Digital Signal Processors,produced by Texas InstrumentInc.in 1983.Fast Fourier Transform(FFT)is a main mathod used for spectrumanalysis.People used to implement FFT by hardware for real DSP,but now if you useTMS32010,you can make software to realize FFT.Using TMS32010,1024 complex FFTcan be finished in 45ms with an accuracy of 0.01dB.TMS32010 has two kinds of RAM,Data RAM(DRAM)and Program RAM(PRAM).If you require FFT to be completedfast,it is important that you must study how to use DRAM reasonablely.This papergives you analgorithm,DDT,and discusses the process to realize FFT on TMS32010.
