    os-tutorial

    os-tutorial

    How to create an OS from scratch

    ...The repository provides step-by-step lessons starting with bootloaders and moving through kernel development, interrupts, memory management, and system calls. Each tutorial is accompanied by clear explanations, code examples, and references to deepen understanding. The project uses x86 assembly and C to illustrate concepts, making it accessible to students and hobbyists interested in low-level programming. By compiling and running the examples with tools like QEMU, learners gain hands-on experience with OS fundamentals. With its structured lessons and approachable explanations, the repository has become a widely recommended resource for operating system beginners.

    NSync

    NSync

    nsync is a C library that exports various synchronization primitives

    ...This approach simplifies concurrency management and often improves readability and maintainability of multithreaded code. The library emphasizes efficiency, with locks and condition variables occupying minimal memory and supporting cancellation mechanisms through nsync_note objects rather than thread-level cancellation. Designed with portability and performance in mind, nsync can be compiled on Unix-like systems and Windows using a C90 compiler.

    UniSIMD-assembler

    SIMD macro assembler unified for ARM, MIPS, PPC and x86

    UniSIMD assembler is a high-level C/C++ macro assembler framework unified across ARM, MIPS, POWER and x86 architectures. It establishes a subset of both BASE and SIMD instruction sets with clearly defined common API, so that application logic can be written and maintained in one place without code replication. The assembler itself isn't a separate tool, but rather a collection of C/C++ header files, which applications need to include directly in order to use. ...

    ZAPH

    Tools and Z80 engine for creating adventure games. (RUST)

    This is an exercise in some advance programming topics using a text adventure as the central result. This originally began as a project to recreate an old BASIC text adventure, on the ZX Spectrum, using Z80. After developing a very simple byte code VM to handle the game interactions, I realised that there was an opportunity to use some more advance techniques, which in turn can lead to some PC based tools.
