High-Performance 32-bit Floating-Point SHARC Processor

Manufactured by:

Product Details

The ADSP-21375 SHARC® Processor family offers the highest MFLOP/$ performance for a variety of applications. The ADSP-21375 device is pin-compatible and code-compatible with prior SHARC Processors such as the ADSP-21367 and ADSP-21369. This member of the SHARC Processor family 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, making them particularly suitable for cost optimized high precision applications.

SHARC Processors also integrate many peripherals designed to simplify hardware design, minimize system design risks, and reduce end-customer time to market. Grouped together, and broadly named the Digital Applications 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 and SPI ports block.

EVAL-21375-EZLITE Circuit Diagram

Product Details

The ADSP-21375 EZ-KIT Lite® provides developers with a cost-effective method for initial evaluation of the ADSP-2137x SHARC® Processors via a USB-based, PC-hosted tool set. With this EZ-KIT Lite, users can learn more about the Analog Devices (ADI) ADSP-2137x hardware and software development tools, and quickly prototype a wide range of applications.

The EZ-KIT Lite includes an ADSP-21375 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.

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).
