Assembly programming: a) Initialize the data memory of the MiniRISC from address Ox50 with the following constants: 20, 40, 60, 80, 100, 120, 140, 160. (2 point) b) Write an assembly routine that reads all 8 values from the data memory, divides them by 4 and accumulates the result in the r9 register. So r9 = 20/4 + 40/4 + should work with any memory content, not only this one. (4 point) + 160/4. The program c) What is the difference between the SRO and SR1 instructions? (1 point)
