But How Do It Know? 8-bit CPU Build

In this, video we look at the ALU, LD, ST and DATA instructions in more detail.

Coming up we'll look at microcode and shift registers, which we will use to simplify the original design introduced in the book.

In video 21 we cover the basics of instruction processing for our CPU:

A short video to add R2 and R3 to the project board:

In the next video we will start to look at instructions!

In this video we look at the example "Doing Something Useful" from the book, which pops up in pages 98 and 105:

Final video in the clock and stepper segment, which goes over the implementation of those parts on our project board:

I've completed video 17, which discusses the Stepper in more detail:

Here's the latest video, the first one of three that will look at the clock and stepper:

In the latest video I add the general purpose R0 and R1 registers to the project board:

Next step: the clock (see book on page 93).

I uploaded the 14th video to youtube this morning:

This completes the ALU portion of the project. Next up will be the installation of the R0 and R1 registers.
