(or its compatible chip) is expensive and has always been a luxury in general PCs. Therefore, unless there is a large amount of scientific computing or a special need, generally 80387 chips are not installed in the PC. Although the current Intel processor has built-in mathematical coprocessor functional components, the current operating system does not need to include the coprocessor simulation program cod

Most of the "mediocre" students, who have excellent intelligence since childhood, get high scores each time without spending too much time doing their homework, because, those students
Ace tips: create a custom service processor in the ace_acceptor framework
Stone Jiang
The ace_acceptor framework makes listening for new connections easy, and also makes it easy to create and activate the derived class of ace_svc_handler for new connections. We have learned about the role of the ace_svc_handle: open () Hook Function and the service processor during initialization. In this article, we take a

Advanced Scheduling
Advanced scheduling is also called job scheduling or long-range scheduling, its main function is based on an algorithm, the external memory on the backup queue of those jobs into memory, that is, its scheduling object is the job.

A few days ago, ARM launched a low-power 64-bit server processor, coupled with Intel's Atom processor, to repeat the low-power server market. Although few users are preparing to purchase such servers, suppliers such as Dell and HP have joined the ranks of low-power servers. Among them, HP said it included the development of low-power servers in the latest product released by Project Moonshot, and will use I

commands, variable instruction lengths, and multiple addressing methods. These are also the disadvantages of CISC, because they greatly increase the difficulty of decoding, however, with the current high-speed hardware development, the speed improvement caused by complex commands is far less than a waste of time on decoding. In addition to the x86 instruction sets used in the personal PC market, CISC is no longer needed for servers and larger systems

Chip Industry analysts said on Wednesday that intel is lagging behind AMD in terms of producing the most powerful processors. Intel last week announced the abolition of the 4G Pentium 4 Development Plan, and AMD on Tuesday launched athlon 64 FX-55 and athlon 64 4000 + two chips, analysts believe that AMD's new chips will be welcomed by the high-end PC market.
Analyst Nathan Brooke Wood said: "a p

Application Analysis of Embedded Linux in network processor-Linux general technology-Linux programming and kernel information. The following is a detailed description. Introduction
In the last 24 months, supplier organizations were facing economic downturn, coupled with the emergence of network processors (multi-core processors) by companies such as Intel IXP and IBM Power NP, Raza, Cavium and Xilinx, this gives Linux more control and management capa

Computer system diagram:
The previous chipset consists of two chips, called nanqiao and beiqiao, which are connected through PCI. Later, Intel replaced beiqiao with MCH (memory controller hub) and ICH (I/O controller hub) with nanqiao. The two were connected using DMI (direct media interface. In addition, the master processor is connected to the chipset through the FSB (front side bus

I have always thought that this book should be called "dedicated processor-centric SOC design", because it does not mean "complex SoC design", but it also means a literal translation of the English name, maybe the author thinks his SOC design philosophy is relatively complicated, or it is specially designed for complicated applications. Let's talk about the source of this book first.
In retrospect, I was still a graduate student
To understand the average load of Linux processors, you may have a full understanding of the average load of Linux. The average load value can be seen in the uptime or top command. They may look like this: www.2cto.com load average: 0.09, 0.05, 0.01. Many people will understand the average load value as follows: the three numbers represent the average system load (one minute, five minutes, and fifteen minutes) in different time periods. The smaller the number, the better. The higher the number,
You may have a good understanding of the load averages in Linux. The average load value can be seen in the uptime or top command. They may look like this:
load average: 0.09, 0.05, 0.01
Many people will understand the average load as follows: three numbers represent the average load of the system in different time periods (one minute, five minutes, and fifteen minutes). The smaller the number, the better. The higher the number, the higher the server load, which may be a signal of some problems o

Java annotations (Annotation) are divided into two categories: annotations that are processed at compile time (Compile times) and annotations that run at runtime (Runtime) through the reflection mechanism. This article will focus on the annotations that are processed at compile time (Compile times), about the annotations that run through the reflection mechanism at run time (Runtime), relatively simple here do not introduce you can find information to learn.

ObjectiveA message processor is a class that receives an HTTP request and returns an HTTP response.When compared to Representative, a series of message processing is linked together. The first processor receives an HTTP request, does some processing, and then passes the request to the next processor. At some point, the response is created and is traced back. This
improve performance and maintain the stability of the IT environment to upgrade to dual cores without disruption to the business. In a highly rack-dense environment, the customer's system performance will be greatly enhanced by porting to the dual core with the same power and infrastructure investment. In the same system footprint, customers will gain a higher level of computing power and performance through the use of dual core processors.
