Computing Fundamentals Tutor 4-Bit CPU 07: Manual Data Entry

This video adds manual data entry to a simulated 4-Bit CPU.

It is one of a series on putting together a simulated 4-Bit CPU, which is the culmination of several series on digital electronics. CPUs are the central processors for computers and many digital devices, and understanding how they work is useful for anyone who is a programmer. This video, which comes after the creation of the workings of the CPU, adds some extra circuitry to allow the user manual data entry, which in turn allows the CPU to be programmed.

This series in turn is part of a larger series that charts the creation of a simulated 4-Bit CPU, with clear explanations of what is happening at every step of the way. Following this Super-Series is a great way to gain a strong understanding of the hardware that underpins computers, and is a great learning experience for anyone interested in computing as a career or hobby.

Roadmap:

Understanding the basics of digital electronics is fundamental to the understanding of computer hardware, and this software allows you to explore that without the need for hardware, soldering irons and the such like.
