Yet another possible feature the MAC instruction can have is auto-incrementing the registers that point to multiplicands. I programmed a Zilog DSP that used the (16-bit fixed-point) Clarkspur core. It...

One thing the others didn't mention is behavior on numeric overflow. In normal processors this usually wraps around from the maximal value to the minimal value.For DSP usage there is often at least an...

The biggest difference between DSP and the standard uController is the DSP's multiply accumulate feature (MAC) that uC does not have. This valuable if you want to perform true digital signal processing...

To be honest the line between the two is almost gone nowadays and there are processors that can be classified as both (AD Blackfin for instance).Generally speaking:Microcontrollers are integer math...

I understand that a DSP is optimized for digital signal processing, but I'm not sure how that impacts to the task of choosing an IC. Almost everything I do with a microcontroller involves the...
