ClearSignal-Auto™ is a package of Software IP, which provides multimode Digital Broadcasting capability in an automotive receiver. Executing on a Blackfin processor by Analog Devices, this is a Software Defined Radio proven solution that has been deployed, amongst others, in high-end German automotive cars.
ClearSignal-Auto was designed to be included in the modern infotainment environment, where the digital receiver is part of a high-tech system and connected to other hardware and sensors, such as mobile phones, navigation and downloaded content.
ClearSignal-Auto can be extended to support a dual-tuner on a single processor, thus performing simultaneously in same band or in two different bands, such as DAB and DRM. It can be used for example for listening to one DAB audio service, while decoding TPEG traffic information or another DAB data service, or for Diversity Reception.
Designed to be quickly and efficiently integrated into an existing system already based on ADI's Blackfin processor, the innovative ClearSignal-Auto maximizes the usage efficiency of the existing hardware resources (DSP and memory), thus leaving a sufficient amount for the existing applications. ClearSignal-Auto can be used on either a single Blackfin processor or in a multiple-chip configuration and the result is a fast and cost-effective development cycle.
A complete Digital Radio solution executed on a single Blackfin comprises:
