Inputing Data to FPGA

Hi, I'm working with image processing.

I have the main blocks working properly on simulation, so now I want to try it on a real FPGA.

I'll use an Altera DE1 or DE2 Kit.

My question is, whats the best way to send data from the PC to the ram memory of the kit?

I was thinking about USART, since I use that with the PIC microcontroller.

Is that an nice way to do what I'm looking for?

And what's the easiest way to do that communication? There's some ready to use USART library, like with microcontrollers?

I'm really new with FPGA communication, so I hope someone could give me some enlightenment.

OBS.: For now I'm just focusing in one frame. One the future i'll try to make some video processing.

I'd really appreciate some help...

Thank you very much!!
