ADSP 21262 to computer connection

Dear experts in Analog Device DSP, I am designing a board centered on an ADSP 21262. I am new to DSP and this one is very complex to me. I would like to interface this board with my computer so as to modify the programs of the DSP for fine tuning thanks to VisualDSP++. Is it possible? If so, what are the proper pins of the DSP to connect for communicating trough USB with my PC?

Thank you very much for your help.

    Hi Verdi,

    Please look at the SHARC Processors Software and Tools page (link is given below) which provides a convenient look-up table to indicate to users what evaluation platforms, extender cards, emulators, software development tools, and middle-ware are available for the specific SHARC processor they have chosen to evaluate for their designs.


    The emulator connected to the JTAG of the DSP is the link between this and Visual DSP++ 5.1.1 running on the computer. The JTAG emulators allows developers to load code, set breakpoints, and observe variables, memory, registers, etc.


    The ICE-1000 (Low Cost USB-based JTAG Emulator) and ICE-2000 (High Performance USB-based JTAG Emulator ) are the latest emulators supports under VisualDSP++ environment. You can find more information about ICE-1000 and ICE-2000 in the below mentioned link,


    You can look into the 'Program Development Steps'(Page No: 58/442) section given in the 'VisualDSP++ User’s Guide' to understand how to create new project, debug and run in the VisualDSP++ environment.


    For more information about connecting to a Debug Session please navigate through the VisualDSP++ HELP via the path given below.
