I read some rumours in a UK magazine that Intel have stopped production of their i82786 graphics co-processor. This seems odd to me as it is quite a new design. For those not familiar with the device, it supports all the usual scan generation and drawing lines etc, but more interestingly it suports hardware overlapping windows and does raterops. According to the article I read Intel were expecting the chip to form the heart of the VGA standard, and when IBM rejected it Intel decided to cease production. This has, according to the article, produced much ill feeling amongst small manufacturers here in the UK. Is the rumour true? If so doesn't this seem a rather less than ethical thing for Intel to do? It was claimed that the small manufacturers in question vowed never to use Intel parts again, some even said they would never use US parts again ( seems a bit drastic to me). But it must be very difficult for small companies if even the large silicon companies can't be trusted to continue to supply current parts. I realise that some parts must eventually die out, but as I have said this is a newish design. If this rumour is true then I am interested what implications this has to the current RISC market. If manufacturers are going to stop production of chips because sales are not as high as hoped for then what happens if the 29000/88000/i860/MIPS/SPARC/.... etc. doesn't sell, will the manufacturers keep production going?? There are so many RISCs on the market at present that they can't all be successful, so does this mean that unless you back the winning horse you might be left with no supply at all ????

In cases where you are worried about this, like your company depends on some part, there is a way to protect yourself. Lore has it that it is possible to get production rights if the supplier decides to stop making it. If you can, get the agreements signed before committing to the part. Now I imagine some suppliers might not want to sign such an agreement, like they might not want to give away all their process information if it is a custom process. Then it's your decision if you want to take a risk on the part, or perhaps use one from another vendor that may not be as good. Other approaches include buying up-front the entire volume you think you will ever need. (If the supplier won't sell them to you, it should give you a real strong hint as to what is going on.) This, naturally, may be impractical for a small company. If you do have production rights, and the process isn't too obtuse, you should be able to get the chip made. It will probably end up costing more, since the volumes aren't there. -Stan my opinions alone etc.

This is actually a different situation, because of the software implications, i.e., devices intended to be reprogrammable devices visible to users: a) Not only need to be built for a (reasonably) long time, but b) Had better have followon products that are compatible Hence, choice of a CPU is an even higher-stakes game than choice of a peripheral chip. When a company picks an architecture, it's probably making a 5-10-year committment, and so they think hard about it. These things come in cycles: in the early 80's, there was a fight amongst the various CISC chips, and it took a few years for things to settle out; as you note, the current fight amongst RISCs is similar. Anybody has a choice, whose extrema are: a) Make a very early choice, hoping to get ahead of the competition, taking the risks that the parts may not be the long-term winners, or even, may be withdrawn from the market, which happens, even sometimes from large companies. Not every part described in the trade press is actually built. b) Make a very late choice, where the winners are obvious, but there is no technology advantage over the competition. I've used the analogy before, but it bears repeating: doing a), that is, picking your CPU early in the game, is like playing Russian Roulette where you pick your CPU, pull the trigger, and then wait 1-2 years to see if you've blown your brains out. -- -john mashey DISCLAIMER: <generic disclaimer, I speak for me only, etc> 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.

There's also alternative c): c) Choose a processor which doesn't quite make it, but isn't a total loser. The marketing department of your CPU vendor then re-targets it to the laser-printer market. Let's see, which chips have been touted as the "ideal" laser printer controller: 32000, 29000, 2167/9, ...
