As part of its overall WiMAX solution, Tata Elxsi Limited, a design services provider for embedded products, has announced the availability of the WiMAX 802.16d and 802.16e Mac and Phy IPs. The new IP, customized on a Stretch software-configurable processor platform, will be showcased at Embedded Technology 2005, Yokohama, Japan, November 16-18. The demonstration will show video data encapsulated in WiMAX frames being transmitted between 2 WiMAX devices.
Until now, wireless systems manufacturers' and carriers have been forced to use banks of DSPs, FPGAs, and general purpose processors, resulting in expensive systems that are difficult to program. Alternatives like fixed function ASICs and SoCs make it difficult to address evolving protocols and standards. Now, these costly and time-consuming solutions have been addresses by means of a software-configurable processor solution.
The benefits of creating new instructions by programming the Stretch processor with C/C++ include:
- The ability to address multiple markets and diverse applications.
- The ability to rapidly respond to emerging WiMAX standards.
- The ability to quickly and easily add custom features.
- The ability to "future-proof" systems by building in support for field upgrades.
The development agreement between Tata Elxsi and Stretch is expected to yield significant product advances and differentiation opportunities within the WiMAX marketplace. The companies have also begun development on other compute-intensive applications, including solutions for the video and multimedia markets.
Service and availability
The new Tata Elxsi WiMAX IP is available as ANSI C software. This is fully supported by Tata Elxsi's technology teams worldwide for platform customization and integration into products. Tata Elxsi has over 1800 engineers, designers and technology experts engaged in embedded product design services across hardware, software and technologies such as Networking, DSP Multimedia and Wireless.
