New DSP chips that hit low price points and simplify design should help DSP usage continue its solid 25 % per year growth rate. Texas Instruments Inc. recently rolled out a device that hits new price points, while Analog Devices Inc. is ready to unveil a low cost networking and media platform.
TI augmented its C64x line with a pair or processors that push price /performance to new levels. The devices run at up to 500 MHZ, with up to 2,000 mega-multiply accumulate cycles and offer up to 288 kbytes of memory.

At a price as low as $17.95, performance per dollar is six times better than family members unveiled in 2002. The new devices will address low-end telecom applications, medical products, and office equipment in addition to automation and robotic applications. Peripherals include an oscillator eliminating the need for an external package, as well as a number of communication ports.
The parts are software-compatible with previous members of TI’s C64 line, simplifying integration for existing users. Since many of these low-priced products are in highly competitive markets, a number of tools are being offered. Development boards and reference designs are readily available.
Analog Device of Norwood, MA will unveil a new member of its low-cost Blackfin line later this month.(http://www.analog.com/processors/processors/blackfin/)
The new platform will address the many factors that are converging around Internet protocols, including video transfers. ADI pushed Blackfin performance up to 750 MHz earlier this year.
The DSP chip market hit $16.4 billion last year, according to Forward Concepts of Tempe, AZ.( www.fwdconcepts.com/Pages/DSPembed.htm)
The embedded portion is 63 % of that total. Sales should grow at around 25 % this year, but DSP usage may be growing at an even faster clip, since many DSPs are being integrated into system on chip devices, which are not generally included in counts of DSP sales, FC president Will Strauss adds.
TI’s new C64x chips triple the number of mega multiply accumulate cycles of their predecessor. The parts offer six times better performance on the telecommunications aspect of the Embedded Microprocessor Benchmark Consortium tests.
