Does anyone know of an open source VHDL module for writing to an SD card? If not, something that will be of help to me?

I've got a design on an FPGA board that receives data from a GPS antenna. I'd like to write out my lat/long data to a SD card. This is similar to the GPS logger available on Spark Fun, but I'd like to write out at a specific interval (after moving ~70 feet) as opposed to every time data I receive a sentence as the logger seems to do. I don't want to do anything fancy with the SD card, just write out to it. If anyone can help it'd be appreciated.

Someone not too earlier was asking about microSD (i believe it's just smaller)... It's under "PIC to microSD" in the same area. There was a few websites and such shared there. I also have some SD/MMC docs on my website, too.

You're basically going to need an SPI port and a bit of space. I don't know much about FPGA's so I don't know what you'd need to do.
