Re: 1-bit cpu from scratch
@Edv: I certainly hope we can live up to your expectations, and we'll have some fun trying to. But it would be tough to top your grandma. Beer? I've never heard of anybody's grandma brewing beer, but I sure wish mine had - and taught me!

1-bit cpu from scratch
My grandma made everything from scratch; bread, soap, beer, sausage.  Man if we had the recipe for scratch we'd be set!

That being said I have been interested in going through the exercise of machine code by hand to assembler to compiler to IDE for some time.

Re: 1-bit cpu
Thanks!  I am very interested to get some step by step and conversation on this sort of design.

Re: 1-bit cpu
@jg, Thanks for your efforts to dig up what's already been done regarding the MC14500b. I think other work serves to validate the little unit. However, I, for one, will not be looking into it until we've finished with the blog. Not that I care to "reinvent the wheel" nor do I have a NIH syndrome. It simply would take the fun totally out of the project.

Re: 1-bit cpu
@KenwickVS: "Shall we continue, or am I wasting everyone's time?"

I think it's safe to say that the number of comments and "tone" of *most* of the comments (yes JezmoSSL, I *am* looking at you :-)  indicate that you are not wasting anyone's tim eand that there is great interest on all our parts in learning more about this one-bit processor. I must admit that I had heard about thsi processor before, but I've never really looked into it, so I for one am very interested ... especially if you can cast some light on why the original architects made the design / achitectural decisions they did.

Re: 1-bit cpu
@JezmoSSL: "As soon as I have more time I will get round to blogging on here and we will look at  solving design problems with not a processor in sight."

I am aquiver in anticipation ... when will you be sending my your first blog :-)

Re: 1-bit cpu
@JezmoSSL: I think it's clear from this blog that Kenwick *IS* doing this for the challenge -- and for the shear fun of it. Plus, for myself I think it's always really instructive to look at technology that came before and understand what the folks back then did and why they did it -- which is the main "thrust" of Kenwick's "Jurassic HDL" series.

Re: 1-bit cpu
I can't wait for you to show us all how "real" design is done.  However, this little project is just for fun.  Shall we continue, or am I wasting everyone's time?

Ken Boyette has worked around machines all his life, but he's having trouble with the idea of interacting with them the way one would interact with another person.
The little 4-bit Gray code counter presented here can easily be scaled up to whatever size you require...
If you use Google a bit, you can find all sorts of information about both ABEL and CUPL. You might even get off your high horse as a result.
In this column, KenwickVS (a.k.a. Ken Boyette) walks us through the VHDL code for his interpretation of the famous Motorola MC14500B single-bit processor.
We examine the block diagram and instruction set for our recreation of the MC14500B single-bit processor and also create the VHDL entity for our processor core.
