A highly symbolic diagram of a "von Neumann" processor is shown in figure 3 . This figure shows the main components of a simple processor:

• the "Memory" block contains the data and the program to be executed;

• the "PLC" block decodes instructions and sequences the operations to be performed;

• the green block corresponds to functions...
