Spartan OS

Spartan OS is an Operating System developed as a Final Year Project for the Bachelor of Science (Hons) in Software Development at Limerick Institute of Technology http://www.lit.ie/Courses/LC233/default.aspx

Spartan OS is a Multi-Tasking Operating System which explores Human-Machine Interaction. Explores Device IO and Human IO, through the typical point and click GUI interface, in order to allow humans to speak to machines on human terms. Delivered within a 6-month timeframe, starting from a truly blank canvas. Achieves optimal Inter-Process Communication (Data Flow Management) which is invariant to the volume of data, using shared memory and an advanced zero-copy operation policy, to direct the flow of data throughout the system without copying a single byte. Supports the keyboard, mouse and video display adapter, despite having no access to BIOS (Firmware) services, by utilizing industry standard protocols to communicate directly with devices on the same terms as would the BIOS itself. Achieves ergonomic Human IO, by implementing mathematical findings such as Fitts Law, to increase human comfort and productivity in a controlled and configurable manner. The system is capable of error detection and recovery, through the use of checksums and restore points, which hardens the system and provides a high level of reliability with a capacity to self-heal and recover from otherwise fatal error conditions.

Spartan OS is a Multi-Tasking 32-bit Protected Mode Operating System featuring a Graphical User Interface with file associations and is designed with usability in mind. Spartan OS uses an in-memory file system (Ram Disk), and has drivers for the PC Speaker, the Serial Port and the PS/2 keyboard and mouse.

This repository contains both the software implementation, and the research and design documentation.
