BreadSystem is a general-purpose operating system by Jack Eisenmann.

Design specification:

• BreadSystem Architecture
• BreadBytecode Documentation
• BreadSystem Interfaces
• Specification Repository

Software Utilities:

• BreadBytecode Assembler

Right now the operating system design is in a "rough draft" state. I have designed many of the fundamental aspects of the system, but there are details and features I want to add. Such items include, but are not limited to:

• More documentation for when specific permissions are required
• Byte-level specification for the BreadSystem volume format
• Interfaces for additional hardware devices
• Shell for REPL-driven system interaction

There is no implementation of BreadSystem yet. I'm working on making the first implementation.

MOTIVATION

I have built various 8-bit homebrew computers over the past several years. Each time I built a computer, I programmed its own rudimentary operating system. This worked OK for demonstrating the computers, but applications were not cross-platform compatible. BreadSystem provides a common platform for computers I build in the future.

Furthermore, BreadSystem serves as an exploration of alternative operating system architectures. BreadSystem includes several non-standard design elements, such as bytecode-driven applications, a unified heap with rigorous pointer security, and extensible permission logic. These features have been fun to think about and incorporate into the system.
