cryptophone ideas

Anyway, why do you need a DSP? I have read in several places that DSP's are going to be "replaced" by the CPU as time goes on and the CPUs just get more and more powerful.

Yeah, eventually. Analog Devices 2105's cost $12 in quantity 1. They are capable of doing 2 data moves, a 16x16 multiply, a 40 bit accumulate and a prefech of the next instruction all in 100ns. 10 Million Multiply-Accumulates per second. Ever tried that on a 386? For more money, you can get ones with 60ns clocks (16.7 MACS). Eric Blossom
