Kartoffels v0.7, a hobby operating system for the RISC-V architecture, introduces exciting new features. This release adds support for cellular automata simulations, allowing for complex pattern generation and exploration directly within the OS. A statistics module provides insights into system performance, including CPU usage and memory allocation. Furthermore, the transition to a full 32-bit RISC-V implementation enhances compatibility and opens doors for future development. These additions build upon the existing foundation, further demonstrating the project's evolution as a versatile platform for low-level experimentation.
This blog post details the significant advancements made in version 0.7 of "kartoffels," a passion project focused on developing a simulated computer system within a cellular automaton. The author enthusiastically chronicles the new features and improvements, showcasing the expanding capabilities of this unique computational environment.
A central theme of this update is the integration of statistical analysis tools.
