- 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 ?
