Product Details

The fourth generation of SHARC® Processors, now includes the low power floating point DSP products – the ADSP-21478 and ADSP-21479 and offers increased performance, hardware-based filter accelerators, audio and application-focused peripherals, and new memory configurations capable of supporting a single chip solution. All devices are pin-compatible with each other and completely code-compatible with all prior SHARC Processors. These newest members of the fourth generation 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 and their low power make them particularly suitable for battery powered applications or where a higher ambient operating temperature is required.

The ADSP-21479 offers a very low power and high performance – 266 MHz/1596 MFLOPs – in a BGA and LQFP package within the fourth generation SHARC Processor family. This feature of power makes the ADSP-21479 particularly well suited to address the automotive audio and many industrial control segments where low power is a requirement. In addition to its high core performance, the ADSP-21479 includes additional processing blocks such as FIR, IIR, and FFT accelerators to increase the total performance of the system. There is a new feature called Variable Instruction Set Architecture (VISA) that allows the code size to be decreased by 20% to 30% and increase the memory size availability. The fourth generation DSP allows the ability to connect to external memory by providing a glueless interface to 16-bit wide SDR SDRAMs.

Fourth-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 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, SPI ports, S/PDIF Tx/Rx, and an 8-Channel asynchronous sample rate converter block. The fourth generation SHARC allows data from the serial ports to be directly transferred to external memory by the DMA controller. Other peripherals such as UART and Two-Wire Interface are routed through a Digital Peripheral Interface (DPI).

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.

EVAL-21479-EZLITE Circuit Diagram

Product Details

The ADSP-21479 EZ-KIT Lite® provides developers with a cost-effective method for initial evaluation of the ADSP-21478/21479 SHARCs® Processors via a USB-based, PC-hosted tool set. With this EZ-KIT Lite, users can learn more about the Analog Devices (ADI) ADSP-21479 hardware and software development, and quickly prototype a wide range of applications.


The EZ-KIT Lite includes an ADSP-21479 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.


The EZ-KIT Lite also comes with a standalone debug agent board that is removable to allow a user to plug-in an external emulator.
