using negative indexes in arrays should be valid vhdl, but still seems a bit strange.

Not completly strange. If you're doing image processing it can make your life easier when the centre pixel (which will probably be the output location) is (0,0), rather than (128, 128), then you can use the indices as the offset.

But I agree with the other comment, 256x256 is an extreme array, you're essentially transposing an entire RAM. I get the feeling the OP is a software programmer with little hardware understanding.
