Hi Jeffrey
For the moment I am using a board with the good old AL422 on it. But at some stage I expect I will change to SRAM or SDRAM.
The FPGA will be a EP4CE6E22 as used in Hedghog II as I believe its is the largest no of pins available in a QFP package. I don't fancy trying to solder BGA's!
There isn't an abundance of IO pins on the EP4CE6E22 but the switches that are on Hedghog II wont be needed and also the microcontroller will be able to program the video decoder (and modulators if there will be any) which should free up more than enough pins to accommodate a frame store and interface with the microcontroller.
