Short Description of Platform

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:

  • ClearSignal Baseband Decoders
  • ClearSignal Audio Decoders (MPEG-2 Layer II, MP3, HE-AAC and WMA)
  • Customer’s applications
