But How Do It Know? 8-bit CPU Build

So here we are, the last video in the series! We end by talking a bit about some possible modifications/upgrades for those who are interesting in keeping on learning or in taking the project further:  

We are getting close to the end here. In this video, we run some sample programs that are included in the source code for the project.

See https://github.com/patrickleboutillier/jcscpu-hmc/blob/main/Arduino-Main/PROGRAMS.h

In this video we cover the simple assembly language for our CPU, made up of C macros, and also look at how to make the clock run automatically as opposed to manually using the push button:

In this video we learn about IO instructions and the software IO devices that are built into the Arduino:  

Here we add the FLAGS register and the conditional jump circuitry to our project board:

In this video we look at the JMPR and JMP instructions for our CPU: 

In this video we program our computer for the first time!

Here we complete the control section so that we can actually program our computer in the next video!

Before looking at more instructions for our CPU, we take a look at shift registers, which we use for our control word.

This is the first of 2 videos where we look at material that is not covered in the "But How Do It Know?" book as it is specfic to this project's implementation. Here we cover the subject of microcode:

In the next video we will cover shift registers.
