Tip: For a better reading experience, it is recommended to read on a PC! 1 What are Concurrency and Race Conditions In Linux systems, concurrency refers to the situation where multiple execution units (processes, threads, interrupts, etc.) access shared resources simultaneously or alternately, while a race condition refers to the uncertain behavior or errors caused … Read more
When building high-performance, highly concurrent Linux applications, understanding the underlying mechanisms of processes and threads is crucial. <span>fork()</span> and <span>clone()</span> are two core system calls that not only form the basis of process creation but also directly impact the implementation and performance of threads. This article will delve into the workings of <span>fork()</span> and <span>clone()</span> … Read more
Potential Issues in Embedded Development 1 Concurrency Issues The efficiency of concurrent program execution is low when writing bare-metal software. Inevitably, there will be a massive while(1) loop in the main program, which contains almost all the business logic of the project. Since each business logic contains delay functions that cause loop waiting, this leads … Read more
