dspic33
So far, all of the DSP code examples I have found for Microchip's dsPIC33 end up using the Microchip DSP libraries, but I'd like to see the *code* for the libraries themselves, or at least someone's version of typical library functions like correlation. In particular, I'd like to see how 16-bit integer multiply-and-accumulate instructions are used, whether the preferred mode is signed integer, fractional integer, unsigned integer etc. and some of the techniques involved. Do such sources exist, either in C or assembly? Or is there a tutorial somewhere on integer multiplication techniques?
Thanks
