A final example: TC4

In this example, we provide a new simulator that introduces you to some new elements of Python, such as the ability to include the date and time. This final example of a computer simulator brings some of the things we have discussed together and creates a simulator with a 32-bit instruction memory and a 16-bit data memory. Consequently, this is not a von Neumann machine because it has different program and data memories. TC4 incorporates several modifications to demonstrate both simplifications and additions.

We’ll present the code first and then add some comments via the labels that indicate points of interest. Shaded parts of the code have comments following the code:
