how to apply dsplink in my project?

Other Parts Discussed in Thread: OMAPL138

In my project, I want to use the dsp-side of omapl138 to get the data of FIFO maked in FPGA, then the data will be processed in dsp-side, and the processed dada will be sent to the arm-side. Because I want to send the processed data to the remote Access point by wifi.

 I used the EMIFA interface to conect the FPGA.

next, I want to edit a program which can get the data and process the data . That program I edit is in dsp-side based on the sample of MPCSXFER in the dsplink dictionary.

Is  this idea right?

    Lee:

       That should work, and may be the simpler case.

       The other option is to look at the MPLIST module, and sample:  dsplink_linux_1_65_01_06/dsplink/gpp/src/samples/mp_list/mp_list.c

       This gives some structure (a doubly-linked list) to the shared memory so you don't need to create your own FIFO in shared memory, but is a bit more complex.
