Is the x86 Ready for Consumer Appliances?

rckymntrider asks: "By now, it's pretty obvious that the movers and shakers of the PC industry are shifting their attention to consumer electronics. Consumers today demand capabilities from their set-top boxes that PCs already deliver (examples: HDTV and gaming). They just don't want a bulky, hot and noisy PC next to their beautiful new plasma TV. Intel, for instance, announced several initiatives for bringing their technology to the media/home automation front, including the establishment of a $200M fund for companies in that arena (small change if you ask me). As a small manufacturer of media-centric devices (I will not name the company and product -- this is not a plug), I have become very frustrated at the availability of hardware for 'consumer' type of applications. ATX? Micro ATX? Too big. Eighty watt CPUs? You're kidding me! Mini ITX? Better but not powerful enough and *way too expensive*. Besides, every new piece of hardware that comes out is practically designed for Windows, and we all know that this is not the operating system that will drive consumer appliances, right? So to sum it up, do you think that the traditional x86 architecture, even with the advent of PCIX and the likes, is suitable for consumer anything? What other platforms do you see on the horizon that could still offer things like High Definition video capability and not double as mini-heaters? Have you ever heard (or envisioned) of a platform designed for powerful but still cost-effective consumer appliances? VIA tried with their EPIA platform but - in my opinion - they failed. Do you think Intel will do it? If not, then who?"

X86 As a shim

"Is the X86 ready for consumer appliances?"

I'd say so, I have an old 486 chip supporting the short foot on my dryer. It has very low power requirements in this capacity and it does a fantastic job of keeping the dryer from wobbling across the basement floor.

The downside is I have to use plenty of Bounce sheets to keep from ESDing the chip.

Clearing up misconceptions

It seems a lot of people here are assuming that the x86 as an embedded platform somehow still requires an OS like Windows or Linux. It doesn't. Instead, it would probably use an embedded OS like QNX or VxWorks.

The issue here is whether the x86 platform's issues, like excessive heat and power consumption and the requirement for a separate memory controller, outweigh its advantages, like the large variety of hardware already available to interface to everything under the sun and the fact that it's a well-understood architecture.

Now that's out of the way, here's my two cents: the x86 architecture, or at least the implementations currently available, simply isn't cut out for most embedded applications. While x86's limitations have been addressed with lots of extensions (MMX, SSE, 3dNow, etc.), those end up adding complexity and drawing more power than a chip designed without those limitations. Also, the x86's pitiful lack of registers compared to architectures like the PowerPC (another choice for embedded applications that require a good deal of power) means that almost any complex operations mean lots of going in and out of cache, or, worse, main memory. While x86 is acceptable in an environment with a 300W+ power supply and user tolerance for a good deal of noise, it won't cut it in your VCR. x86 might see some use in applications which require rapid development and lots of power, but in most cases there is already a good solution available.
