mouse connected to DE2-115 board. When the mouse moves, the Nios II processor is able to keep
track of the movement and record it in a frame buffer memory. The VGA Controller will overlap the
data stored in the frame buffer with a default image pattern and display the overlapped image on the
VGA display.
