QCPU - A fast, reliable, pipelined CPU made in Minecraft.

The CPU functions on an 8 tick clock, but stalls whenever the storage or data memory is accessed. Jumps are not predicted, the decoders just disable when jumping to a location in the iCache. Immediates are handled through second bytes, as the instruction length is 8 bits & data is too

-------------------------------------------------------------------

Information
8 bit data, 8 bit instruction length
4 stage pipeline - Fetch, decode, execute, optional writeback
32 bytes of iCache/dCache - Can be swapped through software
8 bytes of constant cache
I/O ports, addressable 0-7 but extendable with a custom interface
8 bytes of registers (including 1 zero register) with pointer support
ALU performs opcodes: Increment, right shift, addition, subtraction, exclusive OR
8 pages of 32 bytes each, total of 256 bytes of attachable storage
