Okay... so i guess that it won't be a good idea to try to build a software 
decoder on a dsPIC.. that's just too bad... so, there isn't any advantage to 
using the dsPIC say vs a PIC18 or PIC16 since the best way would be to use a 
hardware decoder... Has anyone compared the different offerings from various 
vendors?? I think that there are quite a few around now...
