Audio Signal Processors

Analog Devices SigmaDSP® allows designers to use the SigmaStudio™ graphical tool with an audio digital signal processor without assembly or C coding. Many SigmaDSP processors also integrate high performance audio ADCs and DACs to build a full audio system on chip. ADI’s SHARC® processors are the leaders in quality audio processing and the Blackfin® processors lead in mobile multimedia.

Blackfin Processors

Blackfin® 16-/32-bit embedded processors offer software flexibility and scalability for convergent applications, including multiformat audio, video, voice, and image processing.

SHARC Processors

ADI’s SHARC® processor family dominates the floating-point DSP market with exceptional core and memory performance and outstanding I/O throughput.

SigmaDSP Audio Processors

SigmaDSP® audio processors are fully programmable, single chip audio DSPs that are easily configurable through the SigmaStudio™ graphical development tool.

SigmaDSP Processors for TV

SigmaDSP® processors are fully programmable, single chip audio DSPs that are easily configurable through the SigmaStudio™ graphical development tool.
