Overview
ClearSignal-Auto™ is a package of Software IP targeted to be executed on fixed point DSP’s, such as Blackfin® processors by Analog Devices (ADI), to provide multimode Digital Radio reception capability in cars. It is a proven solution that has been deployed in high-end German automotive cars.
Learn how to add Digital Radio capability to your infotainment system from this Automotive OEM case study.

Target customer
Automotive OEMs and System Integrators in the infotainment market.

Description
Designed to be quickly and efficiently integrated into an existing HU or into a new design, the innovative ClearSignal-Auto makes maximum use of the existing hardware resources (DSP and memory), for fast and cost-effective development cycles, and can be used on either a single BlackFin or in a multiple-chip configuration. The higher performance Head Units' design can take advantage of the Dual-Tuner option of ClearSignal-Auto, which decodes simultaneously two different (or identical) broadcasts - such as DAB+ and DRM, using a single DSP.

Deliverables
EtherWaves provides its customers with DAB/DAB+, DMB and DRM software libraries, together with comprehensive API. A reference design system is also available, as well as complete documentation for design and testing, usage examples, test vectors and optional integration services.
