1Introduction to the Independent Watchdog The watchdog is a hardware timer whose main function is to forcibly reset the entire system when a software fault or program runaway occurs, allowing it to return to normal operation. It is an independent system that can continue to operate even if the main clock fails, thus ensuring high … Read more
Introduction Voiceprint recognition technology, as an important branch of biometric recognition, is rapidly gaining popularity in fields such as smart access control, voice assistants, and identity authentication due to its non-contact nature, ease of collection, and high security. With the integration of embedded systems and deep learning technology, it has become possible to deploy high-performance … Read more

One of the core tasks of an operating system is task scheduling. Tasks have different names in different operating systems, such as task, thread, or process, with processes typically associated with independent address spaces. The goals of scheduling are to ensure fairness, real-time performance (for real-time systems), maximize CPU utilization, and meet task priority requirements. … Read more

To improve system performance while reducing power consumption, MCUs typically provide four types of clocks: High-Speed External Clock (HSE): Generated by an external high-frequency crystal oscillator. Low-Speed External Clock (LSE): Generated by an external low-frequency crystal oscillator, generally at 32.768kHz, used to drive the real-time clock (RTCCLK). High-Speed Internal Clock (HSI): Generated by an internal … Read more
