CPU instruction tracer

Step through an educational accumulator program and watch PC, ACC and flags.

What the simulator is showing you

The toy accumulator uses immediate inputs for clarity; every step updates an explicit machine state.

Try to predict the next output before changing the input. A prediction is evidence that you understand the mechanism. If the result surprises you, trace the bit values or the stored state explicitly.

Go deeper into the explanation

These experiments are simplified teaching models. The rules are intentional and inspectable, but they do not simulate transistor propagation delay, power consumption, or real processor pipeline details.
