like user spaceThe memory in the kernel is not paged. Difficult to perform floating-point arithmetic during kernel programming The kernel gives each process only a small fixed-length stack Because the kernel supports asynchronous interrupts, preemption, and SMP, you must always be aware of synchronization and concurrencySMP: Symmetric multi-processing system. Common ways to solve competition: spin locks and semaphores. To consider the importance of portabilitysuch as keeping the

Article Introduction: Introductory books for beginners in JavaScript. Since learning the front end design, I've been focusing on Photoshop, Html, and CSS, and I rarely learn JavaScript because I didn't know that the Web page was composed of three parts, content (Html), Appearance (CSS) and action (JavaScript), and JavaScript as a representative part of the action is of considerable importance. A Web page without JavaScript is like a

, but development and maintenance require efficiency, rather than simply pursuing pure semantics and decoupling, the final solution is a trade-off. We need to understand what the ultimate goal of design and development is. This is a tough problem. This writing method can reduce the amount of code, but it requires the cooperation of many people, such as vision, and the requirement should be determined. In case the requirement is modified, congratulatio

design and analysis discussed in the title today is one of them. I have never met the author of a book, but objectively speaking, this book is really good. The content of the book basically includes most of the openrisc code, which basically includes, （1）mmu （2）cache （3）qmem （4）store buffer （5）multip

In this chapter, let's use the SP framework to create a simple message Program (why is this the most simple one? It can also reflect the speedphp function. I personally think that simplicity is beautiful, can also be understood more quickly ~),It is very effective to use instances to learn program development. At the same time, we can also understand the development process of the actual network project.This example will be provided for you to download later ~ First, let's take a look at the req
