Texas Instruments Inc. (TI) released its latest DSP that is based on the TMS320C64x core. The company said that the new TMS320C6418 DSP is optimized to provide a well-balanced combination of performance, memory, peripherals and price tailored for telecom, software radio and terrestrial and satellite broadcasting system applications.

With a BDTImark2000 score of 5,480 at 600MHz, the device complements TI's other DSPs. It features 512KB of L2 memory, a Viterbi coprocessor (VCP) and a capacity for 2,400 16bit MMACs per second or 4,800 8-bit MMACs per second peak performance.

According to a press release, the VCP plays an important role in extending real-time performance of the DSP by offloading the core. TI cited an example: in software radio applications, the Viterbi decoder saves approximately 30 percent of a DSP's processing resources.

Also included are two Multi-channel Buffered Serial Ports (McBSPs) for synchronous serial communication, two Audio Serial Ports, a 16- and 32bit microprocessor Host Port Interface and two I?C control serial ports. Also featured is an on-chip oscillator that lowers overall system cost by enabling developers to use a lower cost crystal in place of an external oscillator.

DSP starter kits, Evaluation Modules

The company also offers development DSP starter kits (DSK) and Evaluation Modules (EVM) for the C6418, including the TMDSDSK6416 DSK priced at $395 and the C6418 EVM available from Spectrum Digital for $995. These tools include a complete offering of easy-to-use examples, tutorials and ready-to-run Reference Frameworks based on TI4s DSP/BIOS and off-the-shelf algorithms. And to further accelerate development, a variety of telecom and communications algorithms are available through the company's eXpressDSP third-party program.

Available for sampling, the C6418 is housed in a 23-by-23mm? flip-chip 288-ball BGA package. Priced at $49.50 each in 10,000-unit quantities, the 600MHz, 512KB TMS320C6418 is expected to be in production by October.
