4.1 8-bit checksum 1. Define six bytes of test data to use for your program. 2. Calculate the checksum with a calculator and record here: __________ 3. Write a program to calculate the checksum. 4. Assemble and test the program with the simulator and compare the result with the value you got in step 2. 5. Make a minor modification of a single byte of your test data and recalculate the checksum. Observe & record the changes in the data & checksum. Original data: _________ Replaced data _________ New Checksum _________ 4.2 16-bit Checksum 1. Define six words (2-byte values) of test data for your program. 2. Calculate the checksum with a calculator and record here: __________ 3. Modify the program above to calculate 16-bit checksum. You need to be very meticulous about all the changes from 8-bit to 16-bit operations. 4. Assemble and test the program with the simulator and compare the result with the value you got in step 2. 5.
