As I have worked as a teaching assistant for C++, I hoped to start learning Java by comparing it with C++. At first glance, Java code does indeed look very similar to C++. But this is just a surface similarity. The primary and most important reminder is: Despite the similar syntax, C++ and Java are … Read more
A Flame Graph is a tool used for visualizing program performance analysis data, helping developers quickly identify performance bottlenecks in their programs. Flame Graphs present call stack information in a graphical format, making complex call relationships intuitive and easy to understand. 1. Principle The core idea of a Flame Graph is to collect the call … Read more
1) <span>inline</span> What is it? Semantics: It suggests to the compiler that “this function can be expanded inline at the call site, saving the overhead of a function call (saving/restoring registers, jumping/returning, etc.).” Not a guarantee: It is merely a suggestion, and the compiler may choose not to adopt it (depending on optimization level, function … Read more

Gift to Readers Conducting scientific research involves a profound system of thought, requiring researchers to be logical, meticulous, and earnest. However, effort alone is not enough; often leveraging resources is more important than sheer hard work. Additionally, one must have innovative ideas and inspirations that look up to the stars. It is recommended that readers … Read more
A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. Determining whether a number is prime is a classic case in C language, involving a combination of loops and conditional statements. Implementation Idea The basic idea for checking whether a number<span>n</span> is prime: A prime … Read more
Dot Product Operation and Multiply-Accumulate The dot product operation is a fundamental operation in DSP applications, commonly used in filter and transformation algorithms. The ARM Cortex-M4 provides efficient multiply-accumulate (MAC) instructions for rapid execution of dot product operations. Example Code int32_t dot_product(int32_t *a, int32_t *b, uint32_t length) { int32_t result = 0; for (uint32_t i … Read more
