Hell, I'll even > throw in my microwave, 'fridge, VCR, Stereo, TV and dishwasher! I found this particularly apt, since I had in my hand a brochure on the ITT DataWave chip. This is intended to go into consumer HDTV sets, will cost $30-$40, and it does 4000 MOPS. A quick rummage came up with the C-Cube CL550 JPEG Image Compression Processor, which will do 9400 MOPS. (And it only does NTSC TV in real time - HDTV requires four CL550's in parallel.) Why so white hot? The C-Cube brochure starts the mind-numbing process by multiplying 24 bits/pixel * 477 kPixels/frame (== NTSC) * 30 frames/second. The ITT brochure starts the mind-numbing process by multiplying 100 M samples/second * 100 operations/sample. I have more compute power in my wristwatch than Eniac had. In a decade, the average household may have a million times more. -- Don D.C.Lindsay .. temporarily at Carnegie Mellon

Humm, so you could network a couple of TVs and a digital audio sound system, instead of purchasing a real parallel processing computer? Hummmm. Use the toaster to handle disk I/O, and the blender to handle print queues and you have a hot backup site for work....but I don't think any of them will have SCSI ports... %%%%% Signature v2.0 %%%%% Doug Mohney, Operations Manager, CAD Lab/ME, Univ. of Maryland College Park * If Apple's pricing strategy had been as exciting as their commercials, * * Windows 3.0 would have never been written *
