  1. Blackvoxel VCPU Architecture

    The Blackvoxel VCPU is a virtual 32 bit CPU designed with it's own instruction set. It's architecture is rather classical and is designed as a learning tool.

    • Full 32 Bit CPU.
    • Designed for teatching and learning (Synthetic and uncluttered instruction set.)
    • RISC typed instruction set (Load/Store paradigm).
    • Some features of CISC : Variable lenght encoded instructions, some complex addressing modes.
    • 8, 16 and 32 bit wide instructions. 
    • Little endian processor. 
    • Top down stack.
    • Interrupts (16 levels).

    The registers of the VCPU :

    • 16 general purpose 32 bit registers (r0-r15)
    • A stack pointer using the general purpose register r15.
    • A status register providing the classical Z,N,V, C flags among others.
    • A Program counter (32 bits.)
