FIFO-issue

[barla]

HI,

1)How to write the FIFO,  from  HOST to Target (DMA)

2)While writing  Target to Host(DMA), is the data is stored into the FPGA.(Or is it stored in the HOST memory)

Hi Barla,

LabVIEW FPGA uses FPGA FIFOs configured for DMA to write to DMA memory and uses FPGA Invoke Methods on the host side to create and read from host memory. The number of DMA channels would depend on the hardware you are using.

You find details on how to do this at the following URL: http://zone.ni.com/reference/en-XX/help/371599C-01/lvfpgahosthelp/fpga_reading_dma/

Hope this helps.
