8Bit Virtual Machine

The virtual machine is not based on any real machine.

CPU

Registers

The CPU has 6 registers, these can be referenced via cpu::Registers. All registers have a size of 8Bit.

IP

This register is used to store the instruction pointer, the instruction pointer points to the address at which the next instruction is located.

ACC

The ACC register stores the last result from an arimethric or logical instruction.

R1-4

These 4 registers can be used by the developers to store any data.
