What Is Zephyr? Zephyr is a new generation real-time operating system (RTOS) designed for various hardware architectures. It offers scalability, optimization, and security, making it one of the preferred choices among developers. Scalability One of Zephyr’s greatest advantages is its scalability. It can be easily applied to various hardware architectures, including ARM, x86, RISC-V, etc., … Read more
Zephyr provides a powerful and extensible time framework for obtaining and tracking timing events from hardware timing sources of any precision. Time Units The kernel time is tracked in the following time units: Real Time Hardware Counter Cycles Ticks Real Time The kernel time is described in real-time units: milliseconds/microseconds, which is easy to understand … Read more
Click the “Deephub Imba“, follow the public account, and don’t miss out on great articles!! Zephyr utilizes dDPO, significantly improving intent alignment and AI feedback (AIF) preference data, following steps similar to InstructGPT. Training Method Distilled Supervised Fine-Tuning (dSFT) Starting from the original LLM, it is first trained to respond to user prompts, traditionally done … Read more
Zephyr provides a set of timing APIs for measuring code execution time, helping to analyze and optimize code. These timing APIs may use a different timer than the default kernel timer, and the timer used is specified by the architecture, SoC, or board configuration. API The timing APIs are defined in zephyr/include/zephyr/timing/timing.h and will only … Read more
Many friends have asked how to develop using Eclipse (and its various modified versions). This question is quite broad, so I can only provide a brief overview. On the last day of the long holiday, let’s discuss software again. If I don’t share something related to hardware soon, many people will secretly ask me to … Read more
ZSWatch is an open-source smartwatch that includes both hardware and software. It is named ZSWatch-Zephyr Smartwatch because it is built on top of Zephyr RTOS. Currently, this project is open-source on Github, and it is a fantastic open-source project~ Zephyr was originally developed by Wind River as a microkernel and became a project maintained by … Read more
