Texas Instruments has released a high-performance DSP optimised to provide a well-balanced combination of performance, memory, and peripherals tailored for telecom, software radio and terrestrial and satellite broadcasting system applications. Based on the company's TMS320C64x core, the new C6418 DSP comes with a BDTImark2000 benchmark score of 5480 at 600 MHz.
The C6418 features 512 Kbytes of L2 memory, a Viterbi coprocessor (VCP) and an impressive capacity for 2400 16-bit million multiply accumulate cycles (MMACs) per second or 4800 8-bit MMACs per second peak performance. The VCP plays an important role in efficiently extending the real-world system performance of the C6418 device by offloading the core. For example, says TI, in software radio applications, the Viterbi decoder saves approximately 30% of a DSP's processing resources.
Also included are key peripherals important for radio and broadcast applications, including two multichannel buffered serial ports (McBSPs) for synchronous serial communication, two audio serial ports, a 16-/32-bit microprocessor host port interface and two I²C control serial ports. Also included 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.
TI also offers development DSP starter kits (DSK) and evaluation modules (EVM) for the C6418. These tools include a complete offering of easy-to-use examples, tutorials and ready-to-run Reference Frameworks based on TI's DSP/BIOS and off-the-shelf algorithms. As all C64x devices use the same instruction set, these tools provide an excellent way for engineers to begin early development of key pieces of a system, specifically algorithms, control code and initial software system integration, without having to wait for first prototypes. Also a wide variety of telecom and communications algorithms are available through TI's eXpressDSP third-party program (see: www.ti.com/c6418pr).
The C6418 is available in a 23 x 23 mm² flip-chip 288-ball BGA package.
