kernel objects require some special initialization (such as the queue header) rather than simply clearing to 0. If the released objects can be fully reused so that no Initialization is required for the next allocation, the kernel running efficiency can be improved. The impact of the splitter on the hardware cache must be fully considered for the organization and management of the kernel object buffer. With the popularization of multi-processor system

-blocking asynchronous three classes, in three ways, non-blocking asynchronous mode of scalability and performance best. This paper mainly introduces two kinds of IO multiplexing modes: Reactor and Proactor, and compares them. actorTwo IO multiplexing modes: Reactor and ProactorGenerally, the I/O multiplexing mechanism relies on an event demultiplexer. The Separator object separates the I/O events from the event source and distributes them to the corresponding Read/write event handler (the event

5. "Object Creation" class modeBypassing new with the object creation class mode avoids the tight coupling (dependency on the specific class) that results from the object creation (new) process, which supports the stability of object creation. It is the first step after the interface abstraction.5.1 Factory methodMotivation:In software systems, it is often the work of creating objects, and the specific types of objects that need to be created often change due to changes in requirements.How to de

, consider extending the 8-bit to 16-bit, one approach is to use splitter to merge the original number with 00000000,Here's a simpler approach, easier to read, and less prone to errorIt can do the "opposite" work when considering discarding bitsExperimentRequirements: Based on your knowledge and experience with Splitter and multiplexers, you can implement a non-trivial combination of logic blocks: ROTR, whi

I. Introduction Recently, I saw an article about qt's window for scaling and sliding, but its code is incomplete. Then I wrote the complete code and made it open-source. A slider in the center of the window can dynamically change the size of the subwindow, and hidden buttons can be used to quickly scale the subwindow. It is as follows:Ii. Details 1. Code (1) slidingwindow. h [HTML]View Plain Copy # Ifndef slidingwindow_h # Define slidingwindow_h # Include Class slidingwindow: Public qw

ObjectiveMany of today's best software uses "multi-vision" technology.The so-called "multi-vision" refers to the same frame window to display multiple views simultaneously.By using this technique, we can provide the user with more information in the limited control of the frame, and make the user interface more friendly, and enhance the operability of the software.Split typeMFC supports two types of splitter windows: static and dynamic.　　static

step is what, in short, there must be read (write) data, and processing data two parts, then this two parts have what characteristics? The read data is primarily I/O operations, while a single I/O operation may have to wait, and I/O operations are less CPU intensive, and most importantly I/O speed is similar to the speed of the CPU. A thread can handle many I/O operations on a wide range of paths, activating the separator when I/O completes, and invoking the event handler by the

technology, like the frequency division multiplexing technology, is widely used. telephones are the most classic examples. In addition, the time division multiplexing technology has also been widely used in radio and television, for example, SDH, ATM, IP, and the communication between CM and cmts in the hfcnetwork is based on the time-division multiplexing technology. 3. Wavelength Division Multiplexing Optical Communication is the transmission of signals carried by light. In the field of optic

As we all know, since Windows 2000, The development driverProgramIt must be based on WDM, but it is difficult to develop and cannot be as easy as developing user-mode applications. To improve this situation, Microsoft has launched a new driver development environment. It should be pointed out in advance that this is not a new one, but a model and encapsulation Based on WDM, which significantly reduces the d

loss of optical distances, costly Optical Fiber replacement, or addition of dispersion compensation equipment. This is undoubtedly a great benefit for network operators. They can use the existing optical fiber facilities to achieve a 10-fold growth in the optical fiber capacity, reaching 8 TB/s or even higher. However, to make such a technology economically feasible, the network must be able to effectively utilize the new optical fiber capacity generated, which is not achieved overnight. From t

plan and construction have been replaced by the fussy of project validation. Unlike the voice-centred networks of the past, the next generation network will be a data-core fusion network. The China Network Communication (Holdings) Co., Ltd., which was born in the tide of telecom reform, was fortunate to be IP/WDM as the Technology Foundation and business platform of the network, and built a backbone network with 40G bandwidth, which lay a good found

When compiling a WDM program, two files are required:Makefile(What is this? You may ask .) For younger programmers, you may not have seen this file. In fact, before the emergence of the vc ide, we must use makefile to determine which files in the project need to be re-compiled. The current ide has automatically completed this job.The job we need to do is to provide such a file with the following content: # # Do not edit this file !!! Edit./sources.

Traditional telecommunication networks are designed for voice transmission. They use TDM and circuit exchange technology. They are not suitable for IP data transmission and video transmission. To meet the needs of voice, data, and video integration in the future, it is necessary to build a broadband integrated man. This section introduces three new man technologies and their applications. 　　Man technology using POS + SDH/WDM Optical Fiber Communicatio

combined with optical transmission system to form all optical network, so the research and development of time division optical switching technology is very fast, and the exchange rate is increased by almost one times every year, at present, several cent optical switching systems have been developed. 1985 NEC successfully implemented the 256MB/S (4-way 64mb/s) color image coding signal of the optical time-division switching system. It uses the 1x4 lithium niobate directional coupler matrix swit
