Last week I asked about general programming reference material along the lines of the hardware reference Horowitz and Hill. I received a few suggestions of excellent resources written around the PIC. Is there any non processor specific references pertaining to effiecient routines for assembly level math etc? I thought I saw a thread back many months ago?
