We're are looking into a co-processor that takes over certain OS tasks.
Specifically, we're thinking about scheduling, interrupts and swaps.
Possibly deadlock resolution.
Any thoughts? References to the literature?
Thanx in advance,

References to the literature? If I remember correctly, many (if not all) of the CDC 6000 series computers used operating systems that ran mostly in the peripheral processors. This freed the CPU to crunch numbers. Some of these operating systems were fairly efficeint, but I never used one that was "nice" for an interactive user. They seemed to be very good at batch throughput. John Unruh ihnp4!ihlpk!jdu

If I remember correctly, this part is NOT a co-processor, but a bundle of peripheral hardware, like a Priority Interrupt Controller and some timers, and some firmware all in one chip. Intel seems to have quietly dropped the thing. I couldn't find more than a passing reference to it in a quick pass over the Intel catalogs. But hey, there are a lot of Intel folks on the net. Perhaps one of them could provide us with more info...
