In 2010, the RISC-V architecture was born at the University of California, Berkeley. Thanks to its streamlined and efficient advantages, it quickly gained support from academia. After nearly a decade of development, the RISC-V architecture has received widespread recognition in both academia and industry, and is also embraced by many chip companies in China. Today, … Read more
[Can Hardware Viruses Burn Hardware?] So-called hardware viruses, the most typical example of which can write garbage data to the BIOS chip, causing the BIOS to fail and thus preventing the computer from starting. The solution is to flash the BIOS program back into the BIOS chip. A notorious trojan known as the BMW trojan … Read more

1. Core Challenges of Real-Time Task Scheduling The real-time requirements of embedded systems dictate that tasks must be completed within strict time limits. This means that scheduling algorithms must consider not only the priority of tasks but also the deadline, execution time, and system resource utilization. Traditional scheduling algorithms such as Rate-Monotonic Scheduling (RMS) and … Read more
Introduction to NuttX NuttX is a real-time operating system (RTOS) that emphasizes standard compliance and small size, applicable to microcontroller environments ranging from 8-bit to 64-bit. In NuttX, the main standards are POSIX and ANSI, and it also incorporates standard APIs from Unix and other common RTOS (such as VxWorks) to achieve functionalities not covered … Read more
