BFCPU (big - fucking - cpu) - greatgamer34 - 03-02-2015
BFCPU ehh, what makes it so special?
Well its got 2 Cores!
RISC - 16 ISA (https://docs.google.com/spreadsheets/d/1...sp=sharing - This is my personal copy so it may be worded stupidly)
Pipelined
There 32 bytes of shared memory for the cpu to use and have fun with.
8 bit ALU
7 local registers
6 bit prom(there is an 8 bit bus available).
Flag queue - 7 deep(maybe 8 IIRC)
Data stack - 8 deep
7 U/I ports
7 pointer addresses
11 tick Data loop
The clock will be under 20 ticks
The first prototype

Shout-outs to Embizone, and newomaster.
The Alu is embi's 4 tick CLE
The Regs are newos
(still not finished)

More information on the instruction set?

Oh my bad, here it is, also i put it in the main post.

I would have liked to see some extensible programming possibilities... such as a call/return or at the very least something that replicates it.
Something that would act as an arbiter for the shared cache if you do add extensible programming.

Sup GG!
I think this project is fantastic. The server really needs more epic projects, rather than the small quicky CPUs right now. In fact, I suggest making it bigger.
Is that 32 registers (quite a lot) or 32 bytes of RAM? The IS link is broken. @Voltz jump and return commands can effectively be functions.
Best of luck!
RE: BFCPU (big - fucking - cpu) - greatgamer34 - 03-06-2015
I have pointer stuffs. Like 7 pointer regs so I have a few ways of getting around with jumping. I have 7 registers attached to each ALU plus the shared 32 Bytes of memory.
RE: BFCPU (big - fucking - cpu) - greatgamer34 - 03-06-2015
The shared memory is like a shared ram basically. xD
RE: BFCPU (big - fucking - cpu) - Chibill - 03-06-2015
Some interesting stuff on that spreadsheet great.
RE: BFCPU (big - fucking - cpu) - greatgamer34 - 03-07-2015
Lol, in a good or bad way?

Not sure there's seems to be some assignment there..
