> Most RISC chips with the latest compiler technology can do better than > most assembly langauge programmers. That entirely depends on the chip, the compiler, and the algorithm being implemented. The above statement seems to be true sometimes, but absolutely not all of the time. What kind of FFT time do you get with a more traditional RISC architecture such as a R3000 (a RISC with a hot compiler) ? Is the odd-ball architecture of the i860 justified by its improved performance ? Jeff Enderiwck jeff@dsp.sps.mot.com
