ADI ADAU1452 SigmaDSP Digital Audio Processor

ADI ADAU1452 SigmaDSP Digital Audio Processor is automotive-qualified and far exceeds the digital signal processing capabilities of earlier SigmaDSP® devices. Its restructured hardware architecture is optimized for efficient audio processing. The audio processing algorithms are realized in sample-by-sample and block-by-block paradigms, which can both be executed simultaneously in a signal processing flow created using the graphical programming tool, SigmaStudio™. The new digital signal processor (DSP) core architecture enables some types of audio processing algorithms to be executed using significantly fewer instructions than were required on previous SigmaDSP generations, leading to vastly improved code efficiency.
