PIC with Automatic Context Saving

[HankMcSpank]

Thanks Darrel.

my fixation is that I want to generate sine waves to very high resolution (DDS) - and all the stuff that abounds on the net seems to be assembly....they all typically generate a fixed timebase by way of an interupt & then in the interupt add a number to an accumulator, do a look up from the result then get out asap. I agree that 50khz is not that onerous...but this is just the first step to total world domination (Mwuahahahaha.) & the interrupt rate will inevitably crank up.

Towards helping me understand this area, (actually I'm just curious) when you say there are still a few cycles that can be saved by going the way I asked about ....do you have a ballpark figure for the auto context saving and your (still excellent!) auto context embracing routine?
