Ensigma DAB IP Enables Successor to Award Winning DAB Digital Radio Tuner


Ensigma a division of Imagination Technologies (“”Imagination””; LSE:IMG) today announced that its digital radio IP is being used in the PURE DRX-701ES DAB digital radio tuner from PURE Digital (formerly VideoLogic Systems.)

The PURE DRX-701ES features the latest highly integrated, third-generation DAB chip, Frontier Silicon’s Chorus™ FS1010. The Chorus processor is a single-chip DAB/Audio processor, based on the META™ processor design and Ensigma DAB IP licensed from Imagination Technologies, and enables PURE Digital to create a high-performance, cost-effective DAB tuner that also massively increases on the features available in previous generation DAB products. The incorporation of this technology also allows the price to be cut by £100 from £349 to £249.

The PURE DRX-701ES is built around Frontier Silicon’s Chorus™ FS1010, a single-chip DAB/Audio processor based on the META™ multi-threaded DSP core and DAB technologies developed by Imagination Technologies’ Metagence and Ensigma divisions. META super-threading technology enables PURE Digital to create a lower cost DAB radio that also increases on the features available in its DRX-601ES DAB digital radio, winner of What Hi-Fi Sound & Vision magazine’s Tuner Product of the Year 2001
