DTS Neo:X for SHARC

Product Details

The DTS Neo:X Decoder delivery from ADI has been highly optimised to run on the Analog Devices’ SHARC processor family. The DTS Neo:X decoder operates on PCM data received either through analog/digital input channels or from a decoder module such as DTS 5.1 decoder. The DTS Neo:X Decoder takes channel configurations up to 7.1 input channels and outputs up to 11.1 audio channels. It contains a standard C-callable ‘push’ API. The module has no dependencies on processor peripherals or registers, adding greater system flexibility and ease of use.

Features

  • Target Processor: Code compatible across the SHARC processor Family ADSP-214xx.
  • Release format: Object code module with C source.
  • Input format: interleaved multichannel 32-bit signed PCM audio samples.
  • Input buffer samples per block: 64 samples per channel.
  • Framework dependencies: None.
  • Output format: interleaved multichannel 32-bit signed PCM audio samples.
  • Sample Rate: 44kHZ and 48kHz.
  • Number of input channels: From 2.0 to 7.1.
  • Number of output channels: Up to 11.1.
  • Multi-threading: Fully re-entrant and multi-instancing capable.
  • DTS certified on ADSP-21462/5/7/9, ADSP-21478/9, and ADSP-21483/6/7/8/9 processors.
