Texas Instruments TMS320C6457 Digital Signal Processor

Texas Instruments’ TMS320C6457 digital signal processor (DSP) is available at speeds of 1.2 GHz and 1 GHz. The C6457 delivers up to 30% more performance at one-third less the cost of current single core DSP processors from TI. This performance improvement is the result of several memory and cache enhancements, while the cost reduction is achieved through a smaller process node. The C6457 is ideal for networking, military, imaging, industrial, medical imaging, radar, vision systems, and test equipment. TMX320C6457 samples are available today in a 23 x 23 mm BGA package. Pricing for the 1.2 GHz version is $146 USD and the 1 GHz version is $112 USD (both in 1K unit volume).
