I'm working with the Spartan development board that has Sram and everything needed on board, and yes, we are using the spartan as a 2 port FIFO. What would i use on the Gumstix to interface to spartan, could you explain that in more detail so i could pass this info to my guys, the time limit for this task is kinda limited so any help would be appriciated. The main idea is to store the final image on Gumstix (on MMC) and process the image with pattern recognition. What image Format as the starting point would we use when reading out the data from the FPGA?
