High-Performance 32-bit Floating-Point SHARC Processor for Professional Audio Applications

Manufactured by:

Product Details

The third generation of SHARC® Processors offers increased performance, audio and application-focused peripherals, and new memory configurations. The ADSP-21368 increases performance to 400MHz while simplifying algorithm development with the integration of a high-bandwidth and very flexible external memory interface. The ADSP-21368 is based on a single-instruction, multiple-data (SIMD) core which supports both 32-bit fixed-point and 32-/40-bit floating point arithmetic formats and is completely code-compatible with all prior SHARC Processors allowing for maximum reuse of legacy code.

The ADSP-21368 increases the amount of on-chip memory to 2Mb SRAM and 6Mb ROM while integrating a variety of audio-specific and general purpose peripherals. Peripherals such as an all digital S/PDIF transmitter/receiver, 8-channel asynchronous sample rate converter, 8 high-speed serial ports, 4 precision clock generators, and multiple serial interfaces combine to ensure the ADSP-21368 maximizes system throughput while minimizing system bill of materials costs.

The ADSP-21368 also provides hardware support for connection multiple processors to a single, shared external memory array. The support includes:

  • Distributed, on-chip arbitration for the shared external bus
  • Fixed and rotating priority bus arbitration
  • Bus timeout logic
  • Bus lock

Product Details

The Blackfin SHARC USB EZ-Extender plugs onto the expansion interface of the ADSP-BF518F and ADSP-21469 EZ-Board and EZ-KIT Lite’s. The EZ-Extender aids the design and prototyping phases of the processor targeted applications and extends the capabilities of the evaluation system by providing a connection between the asynchronous memory bus of the Blackfin/SHARC processor and a USB 2.0 device.

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).

Product Details

The ADSP-21369 EZ-KIT Lite® provides developers with a cost-effective method for initial evaluation of the ADSP-21367, ADSP-21368 and/or ADSP-21369 SHARC® Processor architecture via a USB-based, PC-hosted tool set. With this EZ-KIT Lite, users can learn more about Analog Devices' (ADI's) ADSP-21369 hardware and software development and quickly prototype a wide range of applications.

The EZ-KIT Lite includes an ADSP-21369 SHARC Processor desktop evaluation board along with an evaluation suite of the VisualDSP++® development and debugging environment including the C/C++ compiler, assembler, and linker. The evaluation suite of VisualDSP++ is designed to be used with the EZ-KIT Lite only.

An Analog Devices SHARC USB EZ-Extender daughter board (sold separately) can attach to the ADSP-21369 EZ-KIT Lite using the three expansion connectors, allowing a USB 2.0 peripheral to directly connect to the ADSP-21369 external port and interface with the EZ-KIT Lite.
