Projects
The Knob and Switch (KandS) Computer
The Knob and Switch Computer is a Web-based simulator that will introduce you to the inner workings of a CPU and memory. It is an interactive simulation that allows you to change the computer's settings and view what effect these have.
This simulation comes to us courtesy of Grant Braught of Dickinson College.
- The K&S Datapath Simulation
- This simulator introduces the K&S datapath. The key features are the knobs and switches that can be set to control the operands, operations and storage of the result.
- The K&S Datapath Simulation with Main Memory
- This simulator adds a main memory unit to the datapath to increase the storage capacity of the machine. The key features are that memory accesses require more time than register accesses, and that memory and ALU operations happen in parallel even though one of them will be ignored.
- The K&S with Microprogramming
- This simulator makes the K&S programmable by adding a microprogram store. The concept of microprogramming is intuitive in that the bits of each microprogram simply encode the positions of the knobs and switches.
- The Complete K&S Model 1 Computer
- This simulator is a complete stored program computer. It uses a control unit that translates machine language commands into the microinstructions that carry out the operation. Instructions entered in main memory locations in assembly language are automatically assembled into machine language. The assembly / machine language instructions are documented on the: Assembly/Machine Language Programming Card.
