From the description (automatic translation):
Quote:
I made a compatible machine of the learning 4-bit CPU "TD4" in the book "How to create a CPU".
The 3 minute timer program running toward the end is a program that informs with a buzzer after 3 minutes when running at 1 Hz. The performance is too low to run programs of this size at best.
Since the video was created with an emphasis on crispness, those who want to watch it slowly are recommended to pause.
