ADSP-21266

Highly Integrated 32-Bit Floating-Point SHARC Processor for Home Theater
Manufactured by:

Product Details

The third generation of SHARC Processors, which includes the ADSP-21262, ADSP-21266, ADSP-21364, and ADSP-21365, offers increased performance, audio-centric peripherals, and new memory configurations, including on-chip ROM, that are capable of supporting the latest surround-sound decoder algorithms. All devices are pin-compatible and completely code-compatible with all prior SHARC Processors. These newest 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-perfomance audio applications.

Third generation SHARC Processors also integrate audio-specific peripherals designed to simplify hardware design and 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, an Input Data Port (IDP), Precision Clock Generators (PCG), and timers. This flexibility of resource utilization combined with the ease of use of the SHARC Processor programming model allow manufacturers to leverage a single hardware design for multiple products with varying I/O requirements.

SHARC Melody Platform for the Home

The SHARC Melody platform combines high-performance processors with optimized software, thus offering complete audio solutions to Home Theater manufacturers. The ADSP-21266 is a large memory, high-performance device targeted primarily at mid- to high-end home theater systems. SHARC Melody solutions are offered through on-chip ROM containing industry standard audio decoder algorithms such as

  • PCM
  • Dolby Digital*
  • Dolby Digital EX2*
  • Dolby Pro Logic IIx*
  • DTS 5.1*
  • DTS ES*
  • DTS Neo:6 (Cinema and music)*
  • DTS 96/24*
  • MPEG2 AAC LC
  • MPEG2 (BC) 2 channel
  • 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-21262-EZLITE Circuit Diagram

    Product Details

    The ADSP-21262 EZ-KIT Lite provides developers with a cost-effective method for initial evaluation of the ADSP-21262 SHARC Processor architecture for audio applications via a USB-based PC-hosted tool set. With this EZ-KIT Lite, users can learn more about ADI’s ADSP-21262 hardware and software development and quickly prototype applications.


    The EZ-KIT Lite includes an ADSP-21262 Processor desktop evaluation board along with an evaluation suite of the VisualDSP++ development and debugging environment with the C/C++ compiler, assembler, and linker. VisualDSP++ development and debugging software, along with the USB-based debugger interface, enables users to perform standard debugging functions (such as read and write memory, read and write registers, load and execute executables, set and clear breakpoints, and single-step assembly, C, and C++ source code).

    EMULATOR-USB & HP USB ICE Circuit Diagram

    Product Details

    Analog Devices’ cost-effective Universal Serial Bus (USB)-based emulator and High performance (HP) Universal Serial Bus (USB)-based emulator each provide an easy, portable, non-intrusive, target-based debugging solution for Analog Devices JTAG processors and DSPs. These powerful USB-based emulators perform a wide range of emulation functions, including single-step and full speed execution with pre-defined breakpoints, and viewing and/or altering of register and memory contents. With the ability to automatically detect and support multiple I/O voltages, the USB and HP USB emulators enable users to communicate with all of the Analog Devices JTAG processors and DSPs using either a full speed USB 1.1 or high speed USB 2.0 port on the host PC. Applications and data can easily and rapidly be tested and transferred between the emulators and the separately available VisualDSP++ development and debugging environment(sold separately).

    The plug-and-play architecture of USB allows the emulators to be automatically detected and configured by the host operating system. It can also be connected to and disconnected from the host without opening the PC or turning off the power to the PC. A 3-meter cable is included to connect the emulators to the host PC, thus providing abundant accessibility to hard to reach targets.

    The HP USB-based emulator also supports the Background Telemetry Channel (BTC), a non-intrusive method for exchanging data between the host and target application without affecting the target system's real-time characteristics.
