This is a response to message 8903 about the INMOS Transputer vs. other types of processors. I'm not going to include it here and hope you can just call it up and read it. Anyway, arn't you all missing the point by analysing the "MIPS" rating of these processors and using the results to compare the chips? I followed the Transputer for a couple of years, but became dicouraged because the actual pricing of the component has never even been close to those pro-offered by INMOS at their Transputer seminars. What attracted me to the Transputer was the parallel processing capabilities it supports. This is what the Transputer is all about, and none of the other systems discussed support this type of capability. At the current time I find the University of Lowell's (Mass.) image processing board to be more intresting than the Transputer. First of all, they (claim to) already have the system working, and we're talking 35 MIPS (I mean it will execute 35 million instructions each second) and this INCLUDES MULTIPLY (17x17bits). The system is based upon NEC parts, and basically consists of up to seven 5 MIPS processors which operate in a bucket brigade, and one chip to handle most aspects of communications, including direct access to the Amiga memory. Furthermore NEC claims it will release a 10 MIPS processor version before the end of the year, resulting in 70 MIPS. With multiply on every cycle that seems damn powerful to me! Only problem is the system looks tricky to program. As far as the Transputer goes, I think the Transputer language, OCCAM, would be a natural for the amiga. It supports multi-tasking at the language level, and looks to be fairly complete. Wade.

The Amiga's primitives do not copy messages, but do queue them. Occam assumes that all memory requirements (including run-time stack requirements) can be computed at compile time. The Amiga allocates memory left, right, and centre. This is compatible? Also, the known stack size implies no recursion. This is a point against "fairly complete".
