Communities grow fast when the barrier to entry is small and there is big potential for novelty.

Even on the dsPIC, the DSP instructions are able to do five different things in one instruction - do the MAC, preload registers for the next instruction, increment pointers, store the other accumulator. Efficient DSP code on dsPIC boils down to making use of as many of these features as you possibly can in a given situation!<br>
