Write a MIPS program to implement the following single digit adder:

keyboard input: X+Y=

display output: X+Y=Z

where X and Y are single digits (such as 2 and 7) and Z is the result (such as 9).

Please use keyboard interrupt to read the keyboard input from the receiver data, compute the result Z and use polling (on the transmitter control and transmitter data) to send the output X+Y=Z to the display
