A simple VM written in C++ with it's own little programming language

Simple VM

A simple virtual machine written in C++ using it's own low level language with high level features from host machine like Sleep, etc.

Language

I have written a simple assembly like language called Simple Virtual Emulation and file extension is .svm which contains a few high level instructions.

Instruction	Description
MOV	Moves data from one register to another
MOVI	Moves a static integer into register
JMP	Jumps to a specific instruction index aka address
OUT	Prints register encoded to HEX on host console
OUTI	Prints register on host console
ADD	Adds 1 to a register
NOP	No operation
JE	Jumps to next instruction if 2 registers are equal
JNE	Jumps to next instruction if 2 register aren't equal
HALT	Halts code execution
INT	Interrupts code execution for (static integer) milliseconds
PAUSE	Pause's console on host machine requiring enter to be pressed

Host

This is made for Windows systems but can easily be ported to UNIX. The only host functionality I use that is Windows only is the Kernel32::Sleep function.

Uses

There is really no practical uses for this other than for fun unless you do a few upgrades to it. Have fun and good day.
