Texas Instruments is offering developers a comprehensive portfolio of cognitive radio solutions, based on its TMS320C66x DSP generation. Cognitive radio, a collective term referring to Super Wi-Fi, Wi-Far, Wireless Regional Area Networks (WRAN), IEEE 802.11af, 802.22 and TV white spaces, is geared towards optimizing the use of available spectrum and expanding global access to the Internet.
TI’s KeyStone-based TMS320TCI6614 and TMS320TCI6612 System-on-Chips (SoCs), which encompass a mix of radio accelerators, network and security coprocessors, as well as fixed-and floating-point digital signal processors (DSPs) and an ARM RISC processor, provide the ideal foundation for layers 1, 2 and 3 and transport processing for cognitive radio. TI’s new TMS320C665x processors are also well suited for cognitive radio and consist of three fully pin compatible low-cost, power optimized solutions for developers migrating from single core to multicore.
The TMS320C6657 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 GLOPs and 27.2 GMACs and 13.6 GFLOPs, respectively. Under normal operating conditions, the C6657, C6655 and C6654 power numbers are at 3.5 W, 2.5 W and 2 W, respectively.
Azcom Technology, a leading provider of services and solutions in the wireless communications domain, announced that they are developing a high-performance platform designed to meet the WhiteSpace Alliance’s™ Wi-Far specification for cognitive radio applications. The platform comprises of a hardware board based on TI’s power and cost-efficient TMS320TCI6614 wireless infrastructure SoC and complete PHY / MAC layer stacks. Azcom’s platform enables the TV white space market to support devices from a distance of over 10 kilometers, a major upgrade from current Wi-Fi spots that support devices from a distance of up to 10 meters.
