altos: Add 'void' parameter to ao_fec_decode callback parameter

2012-07-11T03:34:02+00:00

This keeps the compiler from whinging about the lack of a prototype. Signed-off-by: Keith Packard

altos: Viterbi performance improvments. Down to 5.7ms for command decode

2012-07-04T03:59:35+00:00

Stealing more of Phil's good ideas, decoding a command mode packet has been reduced from 9ms to 5.7ms. Lots more comments to help future-me figure out how this code works. Signed-off-by: Keith Packard

altos: Unroll viterbi state loop for >30% performance boost

2012-06-28T02:45:22+00:00

9.3ms vs 14.7ms, a clear win. Signed-off-by: Keith Packard

altos: Clean up radio CRC handling

2012-06-28T00:17:44+00:00

Make the FEC code just set the CRC_OK bit like the cc1111 radio does; eliminates a bunch of weird conventions across the FEC API. Signed-off-by: Keith Packard

altos: Optimize FEC encode and decode

2012-06-27T06:11:10+00:00

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). Signed-off-by: Keith Packard

altos: rename ao_viterbi.c to ao_fec_rx.c

2012-06-27T05:16:44+00:00

Keep it parallel with ao_fec_tx.c Signed-off-by: Keith Packard
