RTOSsseract - RTOS on MicroBlaze (Arty A7-35T)

RTOSsseract is an embedded RTOS project running on the MicroBlaze soft processor inside the Arty A7-35T FPGA. It features UART-based shell interaction, modular peripheral drivers, and simple multitasking — all designed to be minimal, fast, and expandable.

Features

• MicroBlaze Processor: Configured with UART, Timer, and GPIO peripherals.
• RTOS-Style Task Manager: Implements manual context switching for multitasking.
• UART Shell Interface: Includes a login system and shell commands like help, status, and uptime.
• Modular Codebase: Organized into separate modules for peripherals (timer.c, shell.c, etc.).

Software Used

• Xilinx Vivado & Vitis (2024.2 or later)
• Minicom: For UART communication with the shell interface
• Linux Environment: Development and testing

---

Future Enhancements

• Add real-time tasks:
• Enable interrupt-driven task execution.
• Optimize resource utilization to use ~60% of the FPGA's capacity.
• Add external memory support for storing user logs and data.
• Improve the shell interface with more commands and features.
