Hi Jeffery
My plan if it works is to use the second FIFO for interpolation storage, so I can have the discarded line stored twice
The video will be wrote to the FIFO's in such a way that when read back there would always be a kept line in one and a discarded line in the other. The sequence will be as follows, with lines B and E being the discarded lines.
FIFO A FIFO B
line A line B
line B line C
line D line E
line E line F
and so on.
Later on I may try an optimised two line interpolater with the table of coefficients stored on the PIC, I suspect the sequence of storing the lines will need to be more complecated, but that's a long way down the road yet.
