With TI’s KeyStone-based TMS320C665x multicore DSPs, 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.
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.
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. To ease application development, TI offers Telogy VoIP software modules, which are available as a free download. With these software modules, developers can further differentiate their solutions and offerings. TI also offers easy-to-use, low-cost evaluation modules so developers can immediately get started designing with the C6654, C6655 and C6657 DSPs.
