It's the same for all of them: * demodulation, interleaving, convolutional code, etc. is all in the DSP * scheduling (TDMA frame/multiframe/etc) as well as frequency and tx power control is done by the ARM * the interface between layer1 and layer2 (LAPDm) is via serial line and everything L2 or higher runs on the PC. -- - Harald Welte <laforge at gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
