3 Project Testing Program
<< As a testing program, develop an assembly language program to read two 8-bit unsigned input
values from the input device (8 switches) and store them in memory locations 100 and 101, labeled
as A and B, respectively. The starting address of the data (100) is stored in location 102, labelled with
label C, which can be used to refer to the starting address of data using indirect addressing. The
reading of the values and storing them in memory must be implemented using a loop. Then, write
another loop to read the two values from the memory and sum them up. Then, finally display the
result on the output LEDs.
Provide the program as text in Assembly, Binary, Hexadecimal and Decimal. This program can be used
for testing your design. Examples showing the assembly language syntax for the computer system are
given in Appendix B of the project description. >>
