writing to a fpga array from rt application

Solved!
Go to solution

When using the read/write control in a rt application to write to a fixed fpga array is it require to match the array sizes perfectly?  I am assuming that you can write an array that is smaller or equal to the fixed fpga array size without any penalty.

My experience says that writing straight to an array on an FPGA from a host is just a bad idea.  It uses up resources and hogs up some of your bandwidth.  Do have a DMA available to pass the data down?  That's what I would recommend if you have an extra.

You can write any size array to the FPGA IO node; it will be resized to the correct length.  If you write a shorter array, though, I don't know whether the remaining elements will be filled with 0 or something else.
