DSP med højere ydelse og lavere pris

Texas Instruments leverer med den nye 1.2 GHz C64x+ DSP og til 30 højere ydelse til en 1/3 del af kostprisen i sammenligning med eksisterende single-core DSP'er fra firmaet (in english)

Developers of data-intensive signal processing applications will benefit from the increased performance and value provided by the new TMS320C6457 digital signal processor (DSP), available at speeds of 1.2 GHz and 1 GHz from Texas Instruments. 

The C6457 delivers up to 30 percent more performance at one-third less the cost of current single core DSP processors from TI. This performance lift is due to several memory and cache enhancements, while the cost reduction is achieved through a smaller process node.


These improvements provide system savings, greater efficiency and increased design flexibility for networking, military, imaging and industrial markets, in applications such as medical imaging, radar, industrial vision systems and test equipment.

The C6457 delivers 9,600 (16-bit) MMACS of peak performance for a cycle for cycle performance improvement of up to 30 percent. 

Performance improvements is  enabled by 2 MB of on-chip L2 memory (up to 1 MB cacheable), faster 32-bit DDR2 EMIF (667 MHz) and memory, cache and bus architecture enhancements. This gives customers the flexibility to add more channels to their designs as well as increased headroom for additional application features.

The new DSP suppors high-speed interconnect available with Serial RapidIO (SRIO) and gigabit Ethernet MAC serializer/deserializer (SERDES) interfaces for efficient inter-processor communications.

There is  on-chip acceleration for telecommunications applications with two Turbo-Decoder Coprocessors (TCP2) and one Viterbi Coprocessor (VCP2). This increases channel decoding operations to offload the DSP core, allowing more channels on a single processor for system cost savings.  

The nye 1.2 GHz C64x+ DSP is backwards code compatible with other high performance C64x DSPs, which enable legacy code reuse for a significantly shorter development cycleand increased design flexibility.
