1. Introduction FreeRTOS has become the preferred choice for embedded real-time systems due to its small footprint, portability, and flexible customization capabilities. Before delving into the source code, let us review the core requirements of real-time operating systems (RTOS) in the embedded field: Determinism: Predictable task response delays. Scalability: Support for memory usage ranging from … Read more
The open-source FreeRTOS was created by Richard Barry while working at WHIS. WHIS identified all the weaknesses in the functional model and API through a complete HAZOP analysis based on the capabilities of FreeRTOS, mitigated all weak points, and redesigned SAFERTOS using the IEC 61508 SIL 3 development lifecycle. SAFERTOS and its accompanying Design Assurance … Read more

AbstractThis paper presents a virtual prototype-based analysis framework to support comprehensive evaluation of distributed, networked automotive applications. The framework enables functional and timing verification, performance and reliability analysis, while reducing evaluation complexity.Additionally, the framework supports exploration of the design space of the entire system, considering target hardware/software and system environments.The proposed method narrows the evaluation … Read more
1. Project Overview This project is a machine learning-based Partial Discharge (PD) image recognition system that uses the Support Vector Machine (SVM) algorithm to automatically classify different types of partial discharge images. The system provides RESTful API services through the FastAPI framework, allowing it to receive uploaded images and return recognition results. 2. Features • … Read more
Recently, I discovered that Orange Pi has released a new product. Although it hasn’t officially launched yet, various materials and images have already been made available. Just looking at its appearance and name, I was quite taken aback; it’s called Orange Pi R2S This clearly aims to compete with FriendlyARM’s NanoPi R2S, but this time … Read more
If you want to process data at high speed, you need to be familiar with Single Board Computers (SBCs). These computers typically run on Android and Linux operating systems. Orange Pi is a computer that offers good technical features at a reasonable price. This series includes different types of such computers, one of which is … Read more
