TI's new cost-efficient KeyStone multicore DSPs for Enterprise Gateway Developers

With TI’s KeyStone-based TMS320C665x multicore digital signal processors, developers 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.

“Our newest multicore DSPs give gateway developers an all-encompassing solution that meets all of their specialized processing requirements,” said Ramesh Kumar, business manager, multicore processors, TI. “The C665x DSPs deliver the highest levels of performance at targeted channel density while maximizing power consumption. With our new KeyStone devices, we are addressing the specific requirements of enterprise gateway designs and providing developers what’s required to be successful and a differentiator in this competitive market.”

TI’s C665x DSPs provide a balanced alternative that scales for voice processing, signaling and system control. In the face of significant and unpredictable growth in SIP messaging, TI’s DSPs can provide a highly efficient means to augment today’s solutions. TI’s C665x 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 10 KU, TI’s C665x processors consist of three fully pin-compatible, low-cost, power-optimized solutions for developers migrating from single core to multicore. The C6657 features two 1.25-GHz DSP cores, delivering up to 80 GMACs and 40 GFLOPs, while the C6655 and C6654 single core solutions deliver up to 40 GMACs and 20 GFLOPs and 27.2 GMACs and 13.6 GFLOPs, respectively. Under normal operating conditions, the C6657, C6655 and C6654 power numbers are at 3.5W, 2.5W and 2W, respectively.
