Adam Segal, are you saying a programmable DSP programmed to compresses video is cheaper to implement than a custom dedicated ASIC that is designed to compress video for a specific application? Please. On what planet? Your lead paragraph talks about replacing Pentiums. Hardly a competitive statement that elicits notions of cost effectiveness. If you are saying there are no SVC processor custom ASICs(arguable) so the user has no choice other than a DSP, that's hardly proving your point of cost or market superiority. It just shows the market isnít big enough to justify a custom ASIC. A DSP has its place. Flexibility, uniquely customizable, openness to smaller volume opportunities and time to market should be on your slides, not low cost and high volume. As volumes grow the DSP becomes a victim of the flexibility that won it the socket in the first place.

SVC has been a revolution in the making for quite some time, and enabling DSP-based applications to use it will help spread the technology beyond the few high-end areas where is is currently used.

Programmable DSPs are able to perform many functions due to the nature of the programmable DSP core processor and not with the aid of specific HW blocks. Hence, if you are using the DSP cores for Video you are not paying any overhead and majority of customers will utilize all or most of the device components for a typical video application In addition, most video applications enabled by this SW solution will require little or no additional chips or components beyond DDR memory. With regards to ASIC solutions, there is no fully featured ASIC solutions for HD SVC available today in the market neither for encoding nor decoding Lastly, Iíd like to touch on programmable DSP suitability for high volume applications as well as low volume ones. DSP devices offered by Freescale are shipping and planned to ship in tens of thousands per customer for high volume cost sensitive applications. The inherent advantages of such devices make them an ideal choice for a variety of applications at any volume.

These programmable solutions are nice for low volume, expensive applications. The problem is a programmable DSP is designed to do many things, so the overhead one pays for things one does not use is very high. Further, these DSP vendors leave a lot of peripherals to be added externally, further adding to the cost. If one wants to compress video inexpensively get a custom ASIC that compresses video. Questions like, how much memory is required, the cost of the support chips required for an app and the cost of the silicon in volume is conveniently absent for this press release.
