Overview Jt is a design pattern framework for fast implementation of Java applications. Jt has applications in many large mission-critical systems. The framework achieves the following objectives: The framework architecture is based on a messaging design pattern: A framework component can interact with information and perform calculations by sending, receiving, and processing messages. A messaging API is simple, powerful, and loosely coupled; You can use a "

logic, you can still use these stand-alone modules, such as: You can use the cache module to do your caching logic; Use the log module to record your operation information; use Config Module to parse your files in various formats. So Beego not only can be used for HTTP class application development, in your socket game development is also a useful module, which is why beego popular reason. If you play Lego, you should know that a lot of advanced thin

the X86 computer provides only two external pins for interrupts: NMI and INTR. Where NMI is an unshielded interrupt, it is usually used for power off and physical memory parity; Intr is a shielded interrupt that can be interrupted by setting the interrupt shield, which is primarily used to accept interrupt signals from external hardware that are passed to the CPU by the interrupt controller. There are two common interrupt controllers: 1. Programmable

The rendering pipeline is the entire process of OpenGL-rendered scenes and is the process of rendering the objects to the plane. OpenGL's rendering pipeline went through the traditional fixed pipeline (the steps in the rendering process are defined beforehand) to the current programmable way (using the shader implementation), which is mainly due to the development of the current graphics card, the new graphics card provides user-

Introduction to FPGA Introductory knowledge In recent years, due to the use of Field Programmable gate Array (FPGA) is very flexible, and can be unlimited programming, has been more and more electronic programmers love, many friends want to learn some of the FPGA primer to prepare for the industry, now on the FPGA introduction knowledge of books, forums, Tutorials are a variety of different types. The following author also through the search for

Its outstanding performance in 3D graphics makes its other components almost ignored. The outstanding performance of direct graphics and Microsoft's influence make countless hardware vendors fear and constantly follow the changes to develop new graphics processor architectures. At the same time, ATI and NVIDIA are still f

1 Basic ConceptsThe timing mechanism, along with some more visible kernel activity (such as check timeouts), drives the process to switch.Two main timing measurements: Save the current time and date so that they can be returned to the user program through the Ftime () and gettimeofday () system calls. The maintenance timer, which can tell the kernel or user program that a time interval has passed. Timing measurements are performed by several hardware circuits based on fixed-fre

There is also a web-based WebService programming interface. In general, for DOM, the programming interface is represented as a programming interface for programmable objects, where the DOM publishes several

that everyone is familiar with computer memory, so I will not talk about it here. I just want to mention it briefly. The main memory of GPU and CPU is implemented by DRAM, while the cache is implemented by the lower-latency SRAM. The storage structure of GPU and CPU is basically the same. In addition, CUDA better presents the memory structure to users, so as to control program behavior more flexibly.CUDA Memory Model For programmers, memory can be divided into the following two types:

space, because it increases the flexibility of the device. The working principle is to receive analog signals, convert them to 0 or 1 digital signals, and then modify, delete, and strengthen the digital signals, in addition, the digital data is interpreted back to the analog data or the actual environment format in other system chips. It is not only programmable, but also runs at a rate of tens of millions of Complex Instruction programs per second,

instruction can be taken out and decoded simultaneously, which greatly improves the speed of the microprocessor. In addition, transmission between the program space and the data space is allowed , which increases the flexibility of the device. The working principle is to receive analog signals and convert them0Or1Then, modify, delete, and strengthen the digital signal, and interpret the digital data back to the analog data or the actual environment format in other system chips. It is not only

into two aspects: theory and practice. In computer graphics, mathematical knowledge (linear algebra), as an important basic component, is widely used in graphic processing and operations, therefore, it is important to understand the concepts of vector, matrix, plane, and coordinate system. Although the D3DX API simplifies the details of these underlying mathematical knowledge, using the D3DX API can help us understand what is happening in the current scenario and why we need to use these mathem

By default, the Bash command line can automatically complement the full file or directory name. However, we can do more with the Bash command line complement and make it the next glory by making a full command. This tutorial explains how we use the programmable command-line complement (programmable completion) to apply the automatic completion function to options or command-line arguments. For example, af

in a Linux system, when you enter a command and press two TAB , all available commands that begin with the characters you enter are listed. It's not new, maybe you already know. This feature is called command line completion bash completion. by default, theBash command line can automatically complete the file or directory name. However, we can enhance the Bash command completion function and let it reach new heights with the complete command.How we use the
