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).
TI C6457 DSP Highlights
- Based on TI’s 1.2 GHz TMS320C64x+ DSP core
- Up to 30% cycle for cycle performance improvement: 9,600 (16-bit) MMACS of peak performance
- 2 MB of on-chip L2 memory (up to 1 MB cacheable)
- Faster 32-bit DDR2 EMIF (667 MHz)
- Memory, cache, and bus architecture enhancements
- Serial RapidIO (SRIO) and Gigabit EMAC serializer/deserializer (SERDES) interfaces for efficient inter-processor communications
- On-chip acceleration for telecommunications applications with two Turbo-Decoder Coprocessors (TCP2) and one Viterbi Coprocessor (VCP2)
- Backwards code compatible with other high performance C64x DSPs to enable legacy code reuse for a significantly shorter development cycle and increased design flexibility
