What is Memory Mapped I/O? (16-Bit VM in JavaScript 005)

How to implement memory mapped I/O to allow components to communicate over a common bus in a JavaScript virtual machine.

This this episode we implement memory mapped I/O, where the address space is utilised as common bus for components to communicate. =[ 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 =[ 🔗 Links 🔗 ]= - ⭐️ Patreon: patreon.com/lowleveljavascript - 💌 Updates to your inbox: tinyletter.com/lowleveljavascript - Series Playlist: youtube.com/playlist?list=PLP29wDx6QmW5DdwpdwHCRJsEubS5NrQ9b… - Github Repo: github.com/LowLevelJavaScript/16-Bit-Virtual-Machine - Memory Mapped IO: en.wikipedia.org/wiki/Memory-mapped_I/O - Address Space: en.wikipedia.org/wiki/Address_space
