EtherWaves has announced the launching of ClearSignal-Accel, claimed to be the first digital broadcasting receiver accelerator based on a low-cost FPGA.

This latest addition to the company's family of digital radio products enables ODMs and OEMs to add multistandard DAB/DAB+/DMB receiver capability to CE devices, such as Internet radios or MP3 players. By partnering with EtherWaves, manufactures of multimedia processors can deliver complete, feature-rich digital radio solutions using this receiver accelerator.

The device comprises a low-cost off-the-shelf FPGA and a software application. The software is designed to be easily ported to the client's existing processor, such as a DSP or ARM, or to a multimedia processor while consuming minimal resources.

"By using the existing system processor and only adding an FPGA, ClearSignal-Accel enables designers to enjoy the advantages of software-defined radio without having to invest in new processors' costly learning cycles," said Linda Kedem, marketing manager at EtherWaves. "This is achievable via the intelligent distribution of tasks between the software and FPGA for minimizing the size of the FPGA needed and the transfer rate between the FPGA and the processor. The beauty of ClearSignal-Accel's agnostic software is that it is optimized for running together with the customer's applications."

The solution enables the delivery of digital radio functionality without having to invest in new infrastructure, Kedem added.

Supporting multiple broadcasting standardsDAB, DAB+, T-DMB and DRMClearSignal-Accel implements de-facto parallel processing that can be used for a variety of sophisticated features.
