From f1ae622eff60e05c1f5d8f822a3cf6a85750c6cc Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Tue, 26 Jun 2012 23:11:10 -0700 Subject: altos: Optimize FEC encode and decode Integrate interleaving, CRC and padding within the decode/encode functions. Provide for ISR priorities so that the 1120 RX interrupt takes precedence over the other interrupts or we risk losing bits. Optimize the viterbi decoder a bit (goes from 10ms per packet to 7ms per packet).
