TRACE THE EXECUTION

Follow the blue path.

Each step is one processor cycle. The highlighted instruction stays in view while fetch, decode, execute, memory, and writeback move its values through the machine.

Use ← → to step, Space to play, and Shift + → to advance an instruction. Cyan marks state written at the end of a cycle.
