What is difference between USB-7855R and PCIe-7851R with respect to software?

I had been used USB-7855R(FPGA),

recently I am trying to convert the code for 7855R to it for 7851R.


I know that many parts of the code for 7855R should be changed for the application of 7851R

for which I have many troubles.

especially, for data type of FIFO using DMA (Analog input and analog output).



Can someone share any helpful documentation or information for programing the 7851R?

The 7851 is an older device (Virtex-5) vs the 7855 (Kintex-7) so some Xilinx IP will work differently.


Which I/O are you using on the 7855?


Will the 7851 do the same as the 7855?
