you cannot multiply unsigned type and real type (0.5). Real type is not suitable for synthesis. Try /2 instead.

But I still think you have real issues with your architecture. It is very inefficient and written as if it was software. Why do you have to "waste" clock cycles?

Also - what external interfaces are you using? I doubt there are enough pins to output an entire 8x8 array - so why not do the calcualtions serially?

Have you drawn out your circuit on paper?
