I want to implement a modem on a Motorola DSP 56001. Looking for a starting point I did not find anything yet. Maybe you can help me ? Some details: On the board I use, the analog modem signal is sampled with a fixed sampling frequency. This means that I need an implementation of a PLL (Phase-Lock-Loop) to detect the phase changes in the input signal. The type of modem I want to implement is V.27 and/or V.29, although any other modem implementation will do for starters. So if anybody has either of the two parts, please let me know. Even if it is not written in DSP 56001 assembler but in C, I am still interested. Onno Janssen Philips IS, Innovation Centre Aachen Weisshausstrasse P.O.
