Hi,
whatever interface you are going to use, read in the bmp data byte by
byte and follow the format instructions to be able to decode the raw
pixel data.

Remember: VHDL is about hardware design.

Have a nice synthesis.

I'd attempt to read a simpler format than BMP files - try PGM files:
they're a lot easier to read, as the header is simple and there's only
two formats to worry about, rather than the many variations that a BMP
can hide.

Cheers,
Martin
