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 0060H0041H MULT 0061H0042H STORE 0061H0043H LOAD 0062H0044H ADD 0060H0045H STORE 0062H0060H 200061H 120062H 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]Online submission via Turnitin is required for this assignment.Rationale
