DMA FIFO for fpga image processing

Hello 

 

I am working on Image processing. I need to work on FPGA. I need give image input to FPGA and take FPGA output.

I have some queries

 

           1) How many number of data can be sent at a time throuhg DMA

 

            2) It is a DMA FIFO. Can I give 2D array directly to DMA  or it takes serial input only.

 

           3)  Should I use DMA in both host VI and FPGA VI or Can I use only FPGA VI.

 

           4) I need to give the image input to FPGA. AFter processing again I have to take FPGA output.  How many DMA FIFOs should be used for this. I am thinking

         

               one DMA FIFO write and one DMA FIFO Read in both host VI and FPGA VI. What u say!!

 

please clarify. It is better if u send any example for this.

 

 

Thanks

Prashhhh
