It depends a lot on how you want to store the data on the compact flash. If you want to use a file system, such as FAT, so that you can read back the data on a PC, you will need a CPU.

The compact flash controller provided by Altera is meant to be used in SOPC builder with a Nios CPU. I think that you could control it directly from custom hardware, but it won't be easy.

You can find the controller datasheet here (http://www.altera.com/literature/hb/nios2/qts_qii55005.pdf).
