In the C language, pointers are one of the most fundamental, powerful, and easily confused concepts. They are not only tools for accessing memory but also play a crucial role in arrays, functions, structures, and many other areas. Below, I will guide you to fully understand the essence, types, uses, and examples of C language … Read more
Dynamic memory allocation in C refers to the process where the program requests memory from the system at runtime, based on its needs, rather than determining the memory size during the compilation phase. This is key to building flexible and scalable programs. Below, I will comprehensively explain the fundamentals of dynamic memory allocation through concepts, … Read more
Pointers Detailed Explanation (Pointers） In the C programming language, a pointer is a powerful tool that allows you to directly manipulate memory addresses. Understanding pointers is not only key to writing good C programs but also fundamental to grasping core concepts such as memory management, arrays, and function parameter passing. 1. What is a Pointer? … Read more
Recently, I used FreeRTOS in a project and became curious about idle tasks and hook functions, so I wanted to understand what these two are used for. Here, I will share some of my insights.1. Idle TaskThe idle task is a task that is created by default after the FreeRTOS system starts, and it has … Read more

How to excel in embedded systems? This question, when asked, will often receive the answer: master the C language! Today, I recommend a summary of key points in embedded C language written by an expert, which is definitely worth reading. From a syntactical perspective, C language is not complex, but writing high-quality and reliable embedded … Read more
<span>void</span> and <span>void*</span> are fundamental yet very useful types in C programming, especially when dealing with generic pointers (such as <span>malloc</span>, callback functions, etc.), where <span>void*</span> is crucial. 1. What are <span>void</span> and <span>void*</span> Syntax Meaning <span>void</span> Indicates “no type” or “no return value”, commonly used for function return types <span>void*</span> Generic pointer type, can … Read more
In embedded system development, memory management has always been a headache for developers. Issues like memory fragmentation and memory leaks not only affect system performance but can even lead to system crashes. Traditional memory management solutions are often too complex and difficult to adapt to the resource constraints of embedded systems. Now, there is a … Read more
Introduction Compared to traditional LLM inference frameworks (such as HuggingFace Transformers, TensorRT-LLM, etc.), vLLM demonstrates significant advantages in performance, memory management, and concurrency capabilities, specifically reflected in the following five core dimensions:1. Revolutionary Improvement in Memory Utilization By utilizing Paged Attention technology (inspired by the memory paging mechanism of operating systems), the KV Cache (Key-Value … Read more
Implementing Linked Lists in C: Creation, Traversal, and Operations of Singly Linked Lists In data structures, a linked list is a very important linear data structure. Unlike arrays, the elements in a linked list do not need to be stored in contiguous memory locations; instead, they are connected through pointers. This article will detail how … Read more
