    Xinshuo Zhang,

    Please go to the TI Wiki Pages and search for "c6713 training" (no quotes). The old C6x1x training class material is posted to the TI Wiki Pages. It includes information that you need as someone new to this DSP kit, and it includes audio examples that will be good starter code for your project.

    Why do you use the DSK6713? For a new project there are newer devices and boards available with more features.

    Yes, you can use external memory. I am not sure how DSP/BIOS is directly related, but you can use it for your application and you can use it to define your use of memory resources.

    Hi RandyP,

    What I mean is that Dsps achieve their highest performance when running code from on-chip program RAM.If your program will fit into the on-chip program RAM,use the DMA or the Boot_loader to copy it there during system initialization. This method of using DMA or a Boot-laoder is powerfull, but it requires the system designer to set everything up manually.

    My system code cannot fit on chip ,can I use bootloader to copy code and data into out-chip memory?

    It is very common to use external memory.

    You will follow the discussion in the datasheet about using the EMIF Boot Mode to copy the first 1KB into internal memory, then you can have that 1KB of program do any initialization of the EMIF and additional copying that you wish to do.

    In addition to the searches I told you about earlier, please look in the Product Folder of TMS320C6713B for application notes on the use of the bootloader and the external memory. If you do not find what you want on that page, look for additional C6000 application notes at TI.com.

    Regards,
