SD Card on DE1 board

Hello! I was wondering if anyone has a SD CARD controller in VHDL?? I would like to simply save data into SD card without using NIOS 2 processor, is it possible?? Thanks for any help. Michael...

If you don't need a high bandwidth you can use the SD card in SPI mode and use any SPI controller.

But if you intend to be able to read the contents of a specific file instead of just a sector on the SD card, without a CPU it will be difficult. I don't know if there is any hardware only implementation of a FAT filesystem...
