Visualizing a classic CPU in action
Greg James, Barry G. Silverman, Brian S. Silverman · 2010
We present a real-time interactive simulation and visualization of the classic 6502 microprocessor as it executes instructions and processes data. A polygon model of each physical layer of the 6502 was created and transformed into a network of wires and transistors suitable for our logic simulator. Tools were developed to provide constant visual feedback of the work-in-progress, which yielded a correct model immediately after finishing the vectorization. This avoided the errors and long debug phase encountered in similar projects.
