Logisim - A logic simulator I've built an 8-bit CPU in

[GUN]

I just wanted to say that I'm working on a 32-bit version of this 8-bit CPU right now, and writing proper documentation on how to program it (I'll probably write an assembler, too). This will be a more complete CPU with support for 65536 registers and 32-bit unsigned integers up to 4294967296. This is an upgrade of my previous 8-bit CPU, which only supported 128 registers and integers up to 127. The new 32-bit CPU will also support jumps and conditional jumps.

I'll upload the save here when I'm done, but if someone wants it, I can upload the 8-bit CPU too, even though I abandoned it, so it's not quite finished.

lol i made a 32 bit ALU after looking at yours, it works 100% and it can do alot of different ops, but im adding even more, but i would like to see the 8 bit version just to see.

Cool. The next step after the ALU is the instruction decoder which reads the program from the program memory and sequenzes it Here's the 8-bit version, but remember is kinda abugged as I never finished it.

matte, 65536 different register? i dont understand why so many registers would be necessary. unless you meant ram addresses. next step buy alot of IC's and bread board it.

You have 65536 registers in the normal wiremod CPU
Some of the registers are special registers like Keyboard Buffer, Screen Buffer and Screen Clock

Those aren't registers, those are memory cells. "Registers" refers specifically to the named registers such as eax, ebx, esp, ebx, and others.

yeh i guess the distinction here is insignificant in logism, i think the typical registers i was thinking of are those actually integrated into the cpu chip , for fast usage ... which has no bearing when there is no physical device.
