I have learned the memory management unit MMU of S3C2440 over the past few days. I mainly refer to the full manual for Embedded Linux application development. There are two blogs on the Internet, which are also very detailed. However, they are not well understood in the MMU address translation process. Here, I will explain the content in the embedded Linux application development full manual according to my understanding, and add some notes to the image. In case of any errors, please do not give
the number and volume of pots are relatively large, it is difficult to manually find the UIS in (*), but you can writeProgram, Even the steps for pouring water are calculated. The last point to be pointed out is that the UI in (*) is not unique, so the method of pouring water is not unique.

Vue Form Verification plug-in creation process, vue form creation process
Preface
Some time ago, the boss set up the Vue development environment, so we happily came to the Vue from JQ. During this process, I was not happy with form verification. When I saw the vue plug-in section, I felt I could write one, so I started to write a Form Verification plug-in va myself. js. Of course, why not find a plug-in? Vue-validator.
1. I thought about it. Form Veri
Note: Variable Parameter functions are useful only when the parameter is ANSI, even if the parameter is referenced.

, the logic of software code is for the hardware services, just to give full play to the functions of the hardware, so learning the memory management mechanism of Linux, the first thing to learn under the processor architecture of the MMU working principle, so that we understand the logic of the page table mechanism is helpful. (as the low-level software engineer, nothing to turn over datasheet very useful ah, more from the hardware thinking to consider the problem)The MMU is the hardware logic
After learning about Tan haoqiang's Standard C (General C that can be run on any platform), Lao Tan's content helps cainiao get started quickly. The knowledge is mainly focused on syntax, from the very beginning "Hello World", we introduced the program framework of the header file + main function, and then let us understand the variables and arithmetic expressions, it tells us about the variable type, operators of expressions, control flows, functions, and sequential programming models for Proce
