RISC-V OS Instruction Guide: User- friendly documentation outlining essential commands and procedures for operating a RISC-V based system.
A lightweight and open-source operating system named Earth and Grass Operating System has been developed specifically for RISC-V processors. This OS is unique in its design, separating its functionality into three primary layers: Earth, Grass, and Application.
The Earth layer focuses on hardware-specific operations, laying the groundwork for interaction with the physical hardware. The Grass layer handles the hardware-independent aspects, providing a layer of abstraction that engenders more portable code. The Application layer implements key operating system features, supporting higher-level applications. The OS's compact nature, consisting of around 2000 lines of code, renders it suitable for resource-constrained environments.
Being constructed on the RISC-V instruction set, which is both open-source and transparent, positions Earth and Grass as an appealing choice for educational and development purposes.
For those wanting a comprehensive understanding of the intricacies and sometimes enigmatic workings of operating systems, a course on operating systems from Cornell University offers insightful exploration. This course covers nine subject areas, including core operating system functions and advanced operating system concepts. Those preferring a more self-directed approach can refer to existing articles on Hackaday that delve into the details of this project [1][2]. The relevant materials, such as source code and documentation, can often be found through course materials or related projects on platforms like GitHub or academic repositories.
The open-source nature of the RISC-V instruction set, used in the Earth and Grass Operating System, makes it an attractive choice for programming and development purposes, especially in the context of hardware and embedded systems. For individuals seeking a deeper understanding of operating systems, a course on the subject from Cornell University offers a comprehensive exploration, covering both core and advanced concepts with a focus on operating system functions and design, potentially providing insights into the development of this Earth and Grass OS.
