division by zero

Laurent Bovet

Hi all,

Does anybody know what does the system do when a division by zero occurs?

We are running RTX 51 ful kernel on Philips' 80c51, 80c552 and 80c660 controllers.

Thanks,

Laurent.

    Walt,

    Yeah... In my opinion, the use of the word microcontroller has been muddied a bit to include anything that includes some built-in "peripherals." For instance, Motorola/Freescale dub the 68340 a microcontroller, but I think most people would have put that one squarely in the processor category. I think it just comes down to the 8051 being an architecture designed for simplicity.

    I don't know that there was ever a hard-and-fast distinction between "controller" and "processor."

    These days, I believe that Intel refer to the '386 as a "microcontroller" - that's just their view of market segmentation, rather than any specific architectural or functional distinction!
