ADAU1451WBCPZ Datasheet PDF - ADI

The ADAU1451WBCPZ is a Digital Audio Processor that far exceed the digital signal processing capabilities of earlier SigmaDSP® devices. The restructured hardware architecture is optimized for efficient audio processing. The audio processing algorithms are realized in sample-by-sample and block-by-block paradigms that can both be executed simultaneously in a signal processing flow created using the graphical programming tool, SigmaStudio™. The restructured 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. The 1.2V, 32-bit DSP core can run at frequencies of up to 294.912MHz and execute up to 6144 instructions per sample at the standard sample rate of 48kHz. However, in addition to industry standard rates, a wide range of sample rates are available.
