Texas Instruments Inc. (TI) has announced what it claims is a highly dense and scalable solution, including development software and TI's Code Composer Studio IDE, geared for enterprise gateway applications such as session border controllers and IP PBX gateways. The company's KeyStone-based TMS320C665x multicore DSPs allow developers to more effectively meet the specialized gateway challenges of matching voice coding techniques, processing tone and signaling messaging, distinguishing facsimile from voice, converting legacy circuit switched connections to IP and managing and reporting voice quality, detailed TI.

The C665x DSPs provide a balanced alternative that scales for voice processing, signaling and system control, the company noted. The multicore processors provide high scalability as well as a wide range of channel densities, making them an ideal solution for the enterprise environment. The TMS320C6654 DSP at 850MHz supports up to 64 channels of G.729AB, while the TMS320C6655 DSP at 1GHz supports up to 128 channels of G.729AB. The TMS320C6657 DSP at 1.25GHz provides significant head room for applications requiring added density.

Starting just under $30 at 10KU, TI's C665x processors consist of three fully pin-compatible, low-cost, power-optimized solutions for developers migrating from single core to multicore, said the company. The C6657 features two 1.25GHz DSP cores, delivering up to 80GMACs and 40GFLOPs, while the C6655 and C6654 single core solutions deliver up to 40GMACs and 20GFLOPs and 27.2GMACs and 13.6GFLOPs, respectively. Under normal operating conditions, the C6657, C6655 and C6654 power numbers are at 3.5W, 2.5W and 2W, respectively.

To ease application development, TI offers Telogy VoIP software modules, which are available for free. With these software modules, developers can further differentiate their solutions and offerings. TI also offers evaluation modules (EVMs) so developers can immediately get started designing with the C6654, C6655 and C6657 DSPs. The TMDSEVM6657L sells for $349 and the TMDSEVM6657LE, which includes a faster onboard emulator, sells for $549. Both EVMs include a free multicore software development kit, TI's Code Composer Studio IDE and suite of application/demo codes to allow programmers to quickly come up to speed on the new platform, the company added.
