occur during mutual locks, so you also need to handle the situation of mutual locks. Normally, after saving the relevant registers, the system reads the C6, C5, and C13 registers of CP15. The three registers are the Invalid Address Register (FAR), the invalid status register (FSR), and the process number register (which is not well translated by pcp15), which are then processed based on the specific failure type. In the ARM processor, CP15 has three address types: VA, Pa, and MVA. Va (Virtual A

Logical regression (logistic regression, (LR) is a very common classification algorithm in machine learning, which has been widely used in the field of the Internet, whether it is in the advertising system for CTR estimation, the recommended conversion rate in the system, the identification of garbage content in the anti-spam system ... can see its figure. LR is favored by the majority of users for its simp

In the development process of embedded software systems, a large number of applications are developed using C language to improve development efficiency. At the same time, the system often contains some key modules that determine the overall system performance. In order to achieve the best performance, they are often written in assembly language, or in some special circumstances, such as operating hardware, you must also use the assembly language. Functions are an important concept in C language
