1. On the von Neumann, describe the process that the CPU must undertake to read a value from memory and to write a value from memory and to write a value to memory in terms of what is put into the MAR, MBR, address bus, data bus, and control bus ? [5 marks]
2. Suppose that the following instructions are found at the given location in memory:
0040H LOAD 0060H
0041H MULT 0061H
0042H STORE 0061H
0043H LOAD 0062H
0044H ADD 0060H
0045H STORE 0062H
0060H 20
0061H 12
0062H 24
Show the contents of all CPU Registers; IR, PC, MAR, MDR, and AC. You need to provide all steps that reach you the final values. [5 marks]
