High-Performance 32-bit Floating-Point SHARC Processor for Home Theater

Manufactured by:

Product Details

The third generation of SHARC® Processors, which includes the ADSP-21261, ADSP-21262, ADSP-21266, ADSP-21267, ADSP-21363, ADSP-21364, ADSP-21365, and ADSP-21366 offers increased performance, audio and application-focused peripherals, and memory configurations capable of supporting surround-sound decoder algorithms. All devices are pin-compatible with each other and completely code-compatible with all prior SHARC Processors. These members of the SHARC Processor family are based on a single-instruction, multiple-data (SIMD) core, which supports both 32-bit fixed-point and 32-/40-bit floating-point arithmetic formats making them particularly suitable for high-performance audio applications.

The ADSP-21366 offers the highest performance – 333 MHz/2 GFLOPs -- within the third generation SHARC Processor family. This level of performance makes the ADSP-21366 particularly well suited to address the increasing requirements of the consumer, professional, and automotive audio market segments. In addition to its higher core performance, the ADSP-21366 includes additional value-added peripherals such as an S/PDIF transmitter/receiver, and 8-channel asynchronous sample rate converter.

Third generation SHARC Processors also integrate application-specific peripherals designed to simplify hardware design, minimize design risks, and ultimately reduce time to market. Grouped together, and broadly named the Digital Audio Interface (DAI), these functional blocks may be connected to each other or to external pins via the software-programmable Signal Routing Unit (SRU). The SRU is an innovative architectural feature that enables complete and flexible routing amongst DAI blocks. Peripherals connected through the SRU include, but are not limited to, serial ports, SPI ports, S/PDIF Tx/Rx, and an 8-Channel asynchronous sample rate converter block.

SHARC Melody Platform for Home Theater

The SHARC Melody platform combines high-performance processors with optimized software, thus offering complete audio solutions to the consumer audio marketplace. The ADSP-21366, through on-chip ROM, offers industry standard audio decoder & post-processing algorithms such as:

  • PCM
  • Dolby Digital*
  • Dolby Digital EX2*
  • Dolby Pro Logic IIx*
  • DTS 5.1*
  • DTS ES*
  • DTS Neo:6*
  • DTS 96/24*
  • SRS Focus*
  • MP3
  • Graphic Equalizer
  • Balance/Fader
  • Bass Management
  • Delay Management
  • These algorithms are factory mask-programmed, ensuring that single-chip system implementations are realized and system bill of materials costs are minimized.

    * License agreement required from IP holders prior to receipt of silicon samples.

    EVAL-SHAUDIO-EZEXT Circuit Diagram

    Product Details

    The SHARC Audio EZ-Extender provides users the ability to evaluate audio application on the ADSP-214xx EZ-Board/ EZ-KIT Lite. Software examples are provided in the latest update of VisualDSP++.

    The EZ-Extender consists of three Analog Devices AD1939 audio codecs and provides 24 channels of analog audio out, 12 channels of analog audio in. The primary codec operates in both in I2S and TDM mode and can run at sample rates of 48, 96, or 192 KHz. The other two codec are configured to operate in Dual Line TDM mode. The three codecs together can operate in dual line TDM mode for 24 analog channels out and 12 analog channels in at a sample rate of 192KHz.

    The audio input and output is available via multiple RCA connectors. A group of switches are available if a user should decide to evaluate the audio codec inputs and outputs in a differential mode. (NOTE: DB25 to XLR cables are not supplied with the EZ-Extender).
