The scale of installed wind power capacity has repeatedly reached new highs, and the promotion and implementation of grid parity policies mark a new development stage for China’s wind power industry. The increasing service life and maintenance costs of wind turbines demand higher standards for condition monitoring and fault warning. Among the major components of … Read more
The Internet of Things (IoT) is indeed a buzzword today, but most engineers have long recognized that adding connectivity to any electronic device can bring numerous significant advantages. Thus, IoT is a very broad term that encompasses various applications, including everything from CCTV to IP-connected security cameras, as well as connected sensors in factories and … Read more
Today, embedded systems often handle sensitive information such as application code (IP) and data, making security a major concern in their design. To establish a reasonable foundation for judging whether the proposed security system is sufficient to fend off attackers or is overly defensive, it is necessary to identify the perceived security threats. This means … Read more
Due to the unique nature of embedded systems, there are many security threats. First, because embedded systems have limited resources, with small RAM and ROM, and limited processing speed, they cannot simultaneously implement multiple security defense measures, making them vulnerable to attacks. Second, the diverse deployment environments of embedded systems, such as industrial production environments, … Read more

Have you ever worked on low power consumption products? Low power products may seem simple, but to create a low power product, especially achieving ultra-low power consumption, is relatively more challenging. Today, we will discuss the approach to low power design in an RTOS environment. Preface: Programming Mindset The design of embedded products is diverse … Read more
In chip design, power consumption optimization is a key factor determining chip performance, battery life, heat dissipation, and cost. The sources of power consumption mainly involve power supply voltage, clock frequency, number of devices, and process technology (which affects threshold voltage and leakage current). From the composition of power consumption, we can optimize at different … Read more
