Minecraft 8-Bit CPU (RISC)

Hello there. This is my CPU, that i have made in Minecraft.
It's work-in-progress for now. Please, sorry for my english :)

Brief overview:
Easily programmable 56 instruction word @15bit instruction memory.
16 bytes fast-access register file (RAM)
Powerful 9-Operation ALU.
Output register.
High-density code.
Conditional branching (BRLO, BRHI, BREQ, BRNEQ) - 2 Flags.
---
Future features:
Input register
1 Interrupt routine(possible)
More program and data memory.(easily extendable)
Indirect addressing mode(!!)
--
Instruction set:

I will release the save file, when CPU will be completely ready.

UPDATE:
Please sorry for not fulfilling my promises about save file. I can't continue my work on this thing cause of exams and a lots of work. It's about 90% finished now, and is already capable of executing almost every instruction...but still not ready for a release. I hope it will ever be ready...some time :D

@venim1103 @artemonstrick Just wondering what classes you've taken and books you've read to learn this circuitry. I know how to build a complex ALU that can do functions such as (AND,XOR,XNOR,BI-DIRECTIONAL Bit Shift,etc.) but how do you learn about the CPU, RAM, and every other component in this machine?

@chancerogers85 please contact me via private messages, I will send you a bunch of links to a cpu architecture tutorials.

i just threw up

[artemonstrick]

@ChrisSousa9 why?

[smeedlysmeed]

Can you use this thing to calculate the digits of PI and display them on an output?

[artemonstrick]

@smeedlysmeed yes, you can. Could, actually. I've lost my save file. But no worries, i am working on a really cool design right now. stay tuned!

i think i am going to threw up. i've done 256 bytes of good ram... (just have to wait 1,6 sec betwen loading values changed on 5th bit)... and i just want mby to create gpu and see things... but i dont even know how big my screen should be... if i save my screen thats gonna take 1/4 of my memory if its 16 x 16 ;[

This is epic as hell!!! ... I've been wanting to make something like this for a while now but I'm not yet proficient enough (I've been kinda lazy with my studies) and I haven't played Minecraft for a while so I'm not that good with translating real life circuitry to redstone circuitry.

@artemonstrick Cause this thing is too awesome to handle. *explodes*

[MrMagicCreeper]

Now make it IRL :D

dammit no save file :( been trying to build a bloody program counter for the last 3 days >:(

@pghg022 ok thanks for the help fucken dicks
