AMD Buys Pre-VIA Cyrix Media-GX Division
An anonymous reader writes "A long time ago, in what feels like a different universe, Cyrix created the first sub-$1000 PC based on a 2 chip solution called the Media-GX. Soon after National Semiconductor bought Cyrix, keeping the Media-GX team and selling the 686MX team to VIA.
In the meantime, the Media-GX team have created the a series of single chip PCs, and a totally new CPU, the GX2. Now National Semiconductor is
selling the division to AMD, which should give it a higher profile and better fab technology again."
Reader jlouderb reminds us of National Semiconductor's Device Girls promotion, "a lame take-off on the Spice Girls," and points to coverage at eWeek of the purchase.
You can already get single chip systems based on their IA chips if you're doing embedded development: Kontron's X-Board, which just came out. We're using a Kontron PC/104 board with a standalone Geode on it right now and it's the most rock solid board I've ever used. The X-board is going to make our next revision incredibly small, low power, and inexpensive.
Although, I have to wonder what this will do the ZFMicrosystems lawsuit against National. Basically, ZFMicro was started by the original founder of Ampro, which originated the popular PC/104 standard, and integrated a 586 processor core with a bunch of peripherals into the ZFx86, a neat little cheap (I have an MZ104 from Tri-m Systems that uses it. Squeezes a slackware distro into a 6.8MB file on a flash chip). Unfortunately, ZFMicro used National as their foundry and for some of their last-line development. So National got access to schematics and layout info for the chip, instead of just masks. National then proceeded to steal it and integrate the Geode proc they bought from Cyrix with some on-chip peripherals in the same way, and then put ZFMicro out of business by refusing to ship any more ZFx86s.
Does AMD's purchase of low-power technology have anything to do with this?
Everyone will start to cheer when you put on your sailin' shoes.
But there's more! it's not just video on the CPU, it's the north AND south bridges! The CPU, GPU, memory controller, PCI controller, and who-knows-what-else are on this bad-boy! I've been wanting this sort of thing for a long time!
I understand that the price will be longer development cycles and raw performance, but there are a LOT of uses for machines based on this type of thinking. Imagine how inexpensive PCs based on this type of thing could get, and how little power they would require! If managers get their heads around the idea of centralized computing again (as they should in the office) we're going to see huge demand for inexpensive fast-enough graphical terminals.

If you remember the interview with Chuck Moore (of Forth fame) a while back, he was promoting a chip kinda like this. 25 CPUs all on one chip (5x5), with a grid of 18-bit busses, 5 each way, connecting them all to each other horizontally and vertically. He hadn't built any, but based on his previous chips at much larger scales, he was estimating about 2400MHz maximum bus input latency; with 10 independant busses, that means an upper bound of 10*2400M*18=432,000Mbps internal.
:-), nor to listen for any of that "information". But the sheer magnitude of the number is a bit staggering. But anyhow, yes, on-chip busses are pretty fun.
Of course, that's all noise -- none of the chips would have time to do real work
Oh, latest rumor: he took the 25x page down because he'd found a buyer. Very little other info available.
