In this video we establish the core instruction set of the VM, give the VM the capabilities to read and write to main memory, and also to make decisions about how the program should proceed with branching instructions.

=[ ℹ About ℹ ]=

This series is all about building a powerful virtual machine in JavaScript with the following features:

- A flexible, extensible, register-based virtual machine
- Support for signed, unsigned and floating point operations
- A call stack
- Interrupt capabilities
- Ability to do memory mapping for IO
- An assembly language with macro and module support
- A higher level, C like language. We'll use and expand the library from the parser combinators from scratch series
- And finally, to be able to take the whole thing into the browser and exend it to create a sort of fantasy console - an emulator for a machine that never existed
