8 bit CPU - Chibill - 05-04-2014
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.

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

You don't really
Quote:add the IS laterThe 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!
RE: 8 bit CPU - Chibill - 05-04-2014
I have to make the IS before I can post it and I have not yet.
RE: 8 bit CPU - greatgamer34 - 05-05-2014
I see what you mean.
RE: 8 bit CPU - Chibill - 05-07-2014
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
RE: 8 bit CPU - Chibill - 05-13-2014
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)
RE: 8 bit CPU - Chibill - 05-14-2014
That's not a bump.....
RE: 8 bit CPU - Chibill - 05-15-2014
I have finished the memory and know how I will make the instruction decoder work.
RE: 8 bit CPU - Chibill - 06-26-2014
Update: I am rebuilding the memory as the other mem was broken. (I hate buds)
