I got a similar problem: I want to collect 'only' 12 A/D Channels, and do some calulations, but with a frequency of 36kHz. So does anyone think, that is possible somehow with 1. 166 MHz Pentium and 2. the fastest RAM I can get out there, 3. programmed with GNU-C I wrote some math tests to evaluate the speed of a 133 MHz Pentium and it was not so bad - but without an external interrupt or stuff like this. So I also have ... > Two questions: > 1) What is the best way and/or place to learn this?
