These two are not consumer goods.>Medical ultrasound - $20,000 >MRI - $20,000,000 >This is a bit closer to what Bret asked of: Sigma SD14 digital single-lens reflex camera. It costs about 700 USD at amazon.com and as far as I know it uses ADSP-BF561 for image processing. I guess that there are much more examples in the field of embedded multimedia systems. -- Alexander

I still have the $96.50 bicycle I got in 1947. Jerry -- Engineering is the art of making what you want from things you can get. �����������������������������������������������������������������������

DSP is used when it is less costly than the alternatives; it is a cost savings to use a DSP filter rather than a tuned seven-pole wundernetwork. DSP is responsible, in a way, for the cost difference in HDTV using coupled vanadium tuning forks and HDTV with DSP, that actually does show up on the store shelves. Alas, there ISN"T any vanadium-tuning-fork price data easily available for this comparison.
