The Actor Model Applied to the Raspberry Pi and the Embedded Domain

Explore the application of the Actor Model to embedded systems and the Raspberry Pi in this 40-minute conference talk from GOTO Aarhus 2012. Delve into how the Actor Model's properties can address complexities in modern embedded systems, offering a fresh perspective that challenges conventional approaches. Learn about creating layered architectures for hardware modules and partitioning complex systems into smaller units, leading to easier testing, contained runtime errors, and improved maintainability. Discover the benefits of using Erlang in embedded systems, including creating actors, handling communication, and managing process errors. Examine practical applications with the Raspberry Pi, exploring its use in education and peripherals. Gain insights into fine-grain abstraction, universal peripheral/component modules, and ongoing developments in hardware simulation.
