Texas Instruments has released to market its TMS320C6455 digital signal processor (DSP) that offers improved performance, reduced code size plus more on-chip memory and high bandwidth integrated peripherals, including the Serial RapidIO bus for inter-processor communications.
With the 'C6455 DSP, TI claims that developers of telecoms, network and video infrastructure end-equipment and high-end imaging systems will see a system performance gain due to 2x-12x boosts in performance and I/O bandwidth, allowing them to integrate more high-bandwidth channels, achieve higher image definition, and produce more efficient software easily for faster time-to-market.
The new C6455 DSP is fully-code compatible with the previous TMS320C64x devices. It incorporates Serial RapidIO and other new high bandwidth peripherals. New peripherals and features of this chip, as compared to previous 1 GHz C64x DSPs, include:
* Serial RapidIO, featuring up to 25 Gbps interconnectivity, enabling high performance multiprocessing that is 12 times faster than previous external memory interfaces.
* Gigabit Ethernet MAC offering 10 times more Ethernet bandwidth than previous C64x devices.
* DDR2 external memory interface delivering twice the throughput of currently available devices.
* 66 MHz PCI bus interface providing twice the frequency of previous processors.
* 2 MB of L2 memory giving OEMs twice the amount of memory as previous C64x devices.
The DSP's integrated Serial RapidIO bus decreases overall system cost by reducing the need for additional devices used for switching and processor aggregation.
The enhanced C64x+ DSP core adds new specialised instructions that on average, make code 20% to 30% more compact and 20% more cycle-efficient than code based on TI's current advanced C64x DSP architecture. The core can execute eight 16x16 multiply and accumulate instructions per cycle.
TI's Code Composer Studio integrated development environment can be used with the C6455. Customers can begin development immediately, leveraging the C compiler, assembler, linker and simulator currently available.
The TMS320C6455 DSP will be offered in 1 GHz, 850 MHz and 720 MHz versions, in a 697 pin 24 x 24 mm BGA.
