CEVA-HD-Audio Solution

  • Programmable DSP Engine
    A 550MHz CEVA-TeakLite-III is a high performance, yet small die size and low-power DSP core, optimized for audio processing
  • Configurable Memory Subsystem
    The CEVA-TL3210, a highly integrated, compact DSP subsystem, incorporating a CEVA-TeakLite-III core, a configurable cached memory architecture with a small memory footprint, an optional DMA engine for efficient data transfers, and an AMBA standard bridges for easy system integration
  • Audio Software
    CEVA’s open, programmable platform contains a comprehensive set of industry standard audio, speech and voice codecs, optimized for the CEVA-TeakLite-III DSP, taking into consideration typical audio system limitations
  • Complete Software Development Kit (SDK)
    A complete software development suite, including development tools, development boards, software system drivers and RTOS, for easy application development and system integration from initial design through final tape-out

The CEVA-HD-Audio’s optimized HD audio codecs support from 2 channels up to 7.1 channels with various bit-rates. Audio codecs supported include MP3, AAC-LC, HE-AAC, WMA, AC-3, RealAudio, Dolby Digital Plus, Dolby TrueHD, DTS, DTS-HD MA, DTS-HD HR, and others.

The CEVA-HD-Audio is based on the 32-bit CEVA-TeakLite-III DSP core running at speeds of up to 550MHz. The CEVA-TeakLite-III DSP core features native 32-bit processing, including 32-bit multiplier with 72-bit accumulation for full data precision. In addition, its strong bit-manipulation capabilities for stream processing and 32-bit FFT support enable a highly efficient implementation of audio codecs. A well-balanced 10-stages pipeline allows the DSP to support high speed implementations.
