Computing Fundamentals Tutor Memory Bank 02: 2-Bus Register

This video shows the creation of a 2-bus register for a simulated 4-bit memory bank.

It is one of a series on the creation of a simulated 4-bit memory bank (with 16 memory locations) built from basic logic gates. The structure used in this series is widely applicable to different sizes of memory bank. In this video, a previously created 4-bit register is adapted so that it can be used on two different buses, thereby making it suitable for an I/O data register for a memory bank, able to access the internal bus and an external bus.

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.
