Calculate M9K Memory Blocks

Hello,

I try to calculate my need of M9K blocks.

My device (Cyclone III) has 432 blocks and I think that each block can has this sizes:

8192 × 1

4096 × 1

2000 × 4

1024 × 9

512 × 18

256 × 36

If my Clocked Video Input FIFO, buffers 1920px with RGB in parallel, there is a need of two 1024x9 (2*1024x9 = 2048x9) blocks for each color. So I need 6 M9K blocks for this task.

Then I have to calculate the FIFOs of the Frame Buffers. I have a write and read only FIFO depth of 256 and a master port width of 128. 128/36=3.555 => 4. So there are 4 M9K blocks of 256x36 for write and for read FIFO.

Is this right?

Thank you!
