It looks like I am finally getting the folks here to get PCs off the
brain and considering doing some realtime work on more sane platforms!
We (well, me) are considering processors and the VME bus. I can get
enough support for an MVME-147 based system because a vendor uses it in
their product.
However, I was looking at a few things and noticed that there seems to
be a lack of realtime software/operating systems for RISC processor.
Personally, I am not to thrilled with SPARC (not counting the 4/110 I
live on daily), but I have only seen a few offerings for it. I have
seen processor boards using the AM29000 but no realtime support.
I am curious (because I could be looking in the wrong places), are there
realtime operating systems/software/development environments for RISC
processors? Is there a good source that would tell me (a cataloge) what
hardware (VME based) is available using RISC CPUs?
Thanks!

This was designed for "Hard Real-Time" environments, those needing interrupt response times of less than 5 microseconds and context switch times of less than 50 microseconds. The Kernal is SVID and SVVS and POSIX. Short of giving a sales pitch, the performance of this system is very good. It has been well received by the Simulation and C3I markets, Radar applications, etc.. It does a good job of handeling the graphics generation for flight simulators (a la Top Gun stuff). Don't know if this is the kind of stuff you are looking for... If so, get in touch with a local Harris Office. If not (e.g., you don't need microseconds and don't care about Unix) you can probably find other sources. Unfortunately, those companies who have real "real-time" operating systems (milisecond response times or less) require the customer to buy the hardware as well as the software... Steve -- Stephen C.

I don't mean to toot my own horn :-), but Concurrent Computer Corp, for
whom I an employed, happens to be a strong force in the realtime market.
We also just happen to offer a platform based on the MIPS R3000 series
RISC processor that runs RTU - Real Time Unix. It is very powerful,
supporting TCP/IP, NFS, RPC, X-Windows, both att and ucb universes, fast data
acquisition and analysis via laboratory workbench (tm), and SYS5 kernal
compatibility. I'm not in sales, but I bet that a call to 1-800-631-2154
will get you a sales contact that can help you out. PS - This is not to
be construed as an official Concurrent statement of functionality. To the
best of my knowledge, all of the above is true, but like I said, I'm not
in sales.

Motorola also supplies a number of RISC systems based on the 88000 processor. They are active in the real time environment. I would suggest that you contact your local Moto rep for more information.

This must be a very unusual company ... do you really mean that someone in sales knows something about functionality? :-)

Is there a good source that would tell me (a cataloge) what > hardware (VME based) is available using RISC CPUs? > Encore Computer Corporation is in the process of developing a real time symmetric multiprocessor system named the Encore 91 Series computer. It uses 2 or 4 Motorola 88100 CPUs along with Ethernet, dual SCSI channels, RS232 and 16 MB RAM on a single 9U VME board. Software support includes UMAX V with real-time extensions and an optional RT guest OS known as MicroMPX. MicroMPX can be given exclusive control of upto to 3 of the four processors for extreme real-time demands. Both UMAX and MicroMPX are fully multithreaded to get maximum performance out of a multiprocessor environment. The Encore 91 Series is currently in Beta test at several customers and will be shipping sometime next year. Email me or call 305-587-2900 for information from your local sales rep. Encore is a world-wide company recognized as a leader in real-time processing because of its CONCEPT/32 (Gould/SEL) computers. The Encore 91 is the latest product from Encore for its real-time customers. Jim Laurent Greenbelt, MD Office INTERNET: jlaurent@encore.com Encore Computer Corporation

This being an 88100, could you please explain what you mean by "interrupt response time"? Is this the time from INT pin active to first instruction of user handler? Have the pipelines been drained? Has shadowing been enabled? Has the source of the interrupt (I presume there is more than one) been established? Could you please give the clock rate of the part? I'd also be interested in knowing the context switch time with the CMMUs disabled, if any are present. Thanks very much, Tim
