8 bit CPU

[Chibill]

I am working on an 8 bit CPU you with basically GreatGamers ALU.
It will be using a RISC instruction set that I am going to make. It will also support a Co-Prosseser for Faster multiplying and dividing.
I will add the IS later.

[Chibill]

I might also be implementing an Instruction Pipeline in this to add to its thurput.

[greatgamer34]

You don't really

add the IS later

The IS, is how you design your CPU. Dont bother about calling it my ALU, its really based off of Newo's adder. I just added some hardware. If you're using my shifter, Awesome!!!

Good luck. Ill be around to answer your questions!

[Chibill]

I have to make the IS before I can post it and I have not yet.

[greatgamer34]

I see what you mean.

[Chibill]

Anyone have a simple RSIC IS.

Found info http://www.ece.umd.edu/~blj/RiSC/RiSC-isa.pdf

I am going to make it one better and add another register line for the output.

Update still working on a IS

[Chibill]

The IS!

Based off some random predictions I think this CPU might have a 18 tick clock as its fastest safe speed.

nand / nor ?!

Chibill really IS the king of bumps. (Pun intended)

[Chibill]

That's not a bump.....

I have finished the memory and know how I will make the instruction decoder work.

Update: I am rebuilding the memory as the other mem was broken. (I hate buds)
