a) Using real CPU architecture, write and explain the fetch/execute cycle of ADD instruction.

b)Figure 2.1 shows 32-bit instruction format. Based on figure, how many.

1- Instructions we can create?

2- Memory locations we can address?

c) Figure 2.2 below shows the architecture of individual memory cell. Based on this figure, explain how data is transferred between the MDR and memory cell.
