I want to pass data to my FPGA using a DMA FIFO. The FIFO is 1024 elements, but can I write bigger chunks than this from the PC side? I'm not sure if the PC actually allocates a larger memory block to allow this?

I'm pretty sure you can set the DMA on the Host side to be larger. There is a DMA configuration node you can use on the host side to set what the FIFO size is on the host side. The size is set in hardware on the target side.

Thankyou gentlemen. That simplifies my architecture nicely!
