Parallel Computer Simulator

Here is an early simulation which follows the processors as they switch on as power gradually flows from connections at the corner processors.

Java applet cannot run. No screenshot available.

Once active the processors execute a four instruction sequence which causes them to change colour.

  // load value from colour io port into register A
  mov a, COLOR_IO;
  // add 1 to register A
  add a, 1;
  // store value from register A in colour io port   
  str a, COLOR_IO;
  // load value loop into program counter
  mov pc, loop;

For anybody interested in looking at the code for the above demonstration:
