Maybe some knowledgable R.T. folks out there might care to post something about this: it's an important area, and one that doesn't discussed here as much as it deserves. In particular, there are of course serious implications of going faster (which usually implies more caching) and being less predictable (sometimes implied by caching). Maybe some real time folks could post some references, or some descriptions of the different flavors of real-time (as there are quite a few). -- -john mashey DISCLAIMER: UUCP: {ames,decwrl,prls,pyramid}!mips!mash OR mash@mips.com DDD: 408-991-0253 or 408-720-1700, x253 USPS: MIPS Computer Systems, 930 E.
