VGA Controller Problem A VGA controller has its memory. The CPU can write to it bit by bit. A refresh input to the controller causes the controller to sequentially output all its bits on the screen. You are to design such a controller for 32x32 bit screen. It should have 5-bit X and Y inputs with an enable and set input. It means to set the bit at X, Y to the set input when enable is high. From the cycle when the refresh input was high it outputs all bits from 0,0-31,31 one by one every clock cycle. During refresh it neither sees any further refresh signal nor any input to set data.
