Meta AXD Audio DSP IP Platform

The Meta™ AXD Audio DSP IP platform is a complete SoC audio solution that enables decode, encode, pre-processing and post-processing of audio. Controlled via a host processor using either OpenMAX-IL, GStreamer or a proprietary construction-based API, AXD cores have been designed to operate from shared SoC memory resources, minimizing the total solution cost.

AXD IP platforms support both multi-stream and multi-standard operation. The internal use of component based stream construction combined with multi-input, multi-output and multi-instance support provides maximum flexibility.

All codecs and algorithms are supplied as fully optimized binary modules. Comprehensive CODESCAPE tools are also available for licensees wanting to add their own algorithms.

Meta’s unique multi-threading technology provides high performance, even when running solely from high latency SoC memory, as zero-overhead thread switching allows latency to be hidden from the processor’s internal pipeline.
