The "Little Man" Computer - Example

In this short video I use one of the prebuilt script courtesy of Petter Higgson.

The simulation shows the adding of two numbers and the calculation of the result. Watch carefully as the LMC Feteches then Decodes and Executes the instructions.

All simulators that are shown on this website are dramatically slowed so that you can follow the process that is being carried out. Under normal circumstances the processes would be carried out much more quickly and obviously dependent on the clock cycles of the specific processor (MHz or GHz per second).
