Product Details

The SHARC ADSP-2146x evaluation boards provide developers with a cost-effective method for initial evaluation of the ADSP-21469 and ADSP-21467 SHARC^® Processors via a USB-based, PC-hosted tool set. With these kits, users can learn more about the processors hardware and software development, and quickly prototype a wide range of applications.

This evaluation boards is designed to be used in conjunction with either the CrossCore^® Embedded Studio (CCES) or VisualDSP++^® development environments to test the capabilities of the ADSP-2146x SHARC processors.

The development environment aids advanced application code development and debug, such as:

Create, compile, assemble, and link application programs written in C++, C, and ADSP-21469 assembly
Load, run, step, halt, and set breakpoints in application programs
Read and write data and program memory
Read and write core and peripheral registers
Plot memory

Access to the processor from a personal computer (PC) is achieved through a USB port or an external JTAG emulator. The USB interface of the standalone debug agent gives unrestricted access to the ADSP-21469 processor and evaluation board’s peripherals. Analog Devices JTAG emulators offer faster communication between the host PC and target hardware.
