Technical discussions about the TI C6000 DSPs (including the c62x, c64x and c67x DSPs).

Hi, c6x developers. I've founded the FFT function "cfftr2.asm". It contains both C and asm sourse, and asm is hand optimized. But TI's FFT operates by float array, when my programm needs a FFT under a DOUBLE array. I changed in C code float to double, but benchmark test told me about terrible speed of such fft. I tried to optimize C code using guide from TI, but result didn't satisfy me. My code is too slow against TI's. So If U have, or have seen FFT with 64 bit values, please tell me where or let me use your library. Real Thanks to everybody. Evgeniy P. |
