LONDON A complete software-defined radio (SDR) developers’ kit to speed the design of wireless communications applications for defense, civilian and commercial sectors is the first result of the cooperation deal between Celoxica and Sundance Multiprocessor Technology.
The kit combines Celoxica (Abingdon, England) ESL software for C-based design of SDR waveforms and Sundance (Chehsam, England) COTS development boards populated with DSP and FPGA devices. Combining C-based and model-based design methodologies with pre-configured IP and programmable FPGA and DSP modules will enable rapid implementation of the complex signal processing tasks required by SDR.
An open application programming interface (API) specifications is provided with the kit to support the fundamental open architecture of SDR and enable creation of SDR models and IP to a single set of interfaces, independent of board level detail.
According to Jeff Jussel, vice president of worldwide marketing for Celoxica, the dynamic reconfiguration and parameter selection of SDR is seriously undermined if developers cannot quickly respond to evolving standards, protocols and the need to quickly deploy or upgrade new network equipment and services. “Equipment manufacturers want a system that can support different standards with a common platform and we can help them achieve that, more quickly and flexibly than was previously possible.”
SDR should provide a solution based on open architectures, reconfigurability and ubiquitous connectivity for the challenges of the evolution of link-layer protocol standards such as 3G and 4G, air interface standards such as GSM/TDMA and IS94/ CDMA and rising network operator deployment costs.
A range of radio applications such as Bluetooth Wireless LAN, Radar and GPS can be realized using SDR with the radio functions being implemented as software modules, or multiple software modules on programmable hardware platforms.
“Sundance’s contribution to the kit provides the optimum mix of high-performance hardware and software technologies that can be reconfigured to perform different tasks and meet different radio standards,” said Flemming Christensen, managing director of Sundance.
The SDR Kit, supplied with interchangeable modules mounted with Xilinx FPGAs and TI DSPs has design software support from Celoxica’s DK Design Suite and system level APIs, the Mathworks Simulink, TI’s Code Composer Studio and System Generator from Xilinx.
