Design and synthesize a simple point of sale (PoS) terminal on the DE-1 board with the following features:
Â· The cost of individual items may be entered using a small 12-key numeric keypad (interfaced to the DE-1).Â Assume that the
item costs will be integers only, up to $99
Â· Display the entered numbers on the VGA terminal.Â You can use the seven segment displays during initial testing.
Â· Press Â‘*Â’ between items and Â‘#Â’ to sum the total.
Â· Enter an amount tendered and calculate the change.
