At present, embedded multi-core processor has been widely used in the field of embedded devices, but embedded human system software development technology still stay in the traditional single-core mode, and do not give full play to the performance of multi-core processor. Program parallelization optimization At present in the PC platform has certain use, but in the embedded platform is very few, in addition

This chapter is selected from the Intel official documentation and translated by myself. Note that the following English word cache is used. If C is in uppercase, that is, cache, it indicates the term "cache". If C is in lowercase, that is, cache, indicates the verb -- indicates saving data to a high-speed buffer storage. Intel 64 and the IA-32 architecture provide the ability to manage and enhance the execution of multiple processors connected to the same system bus. These include:

period.APTAnnotation Processing Tool is a built-in Tool for javac to scan and process Annotation information during compilation. From JDK 6, apt exposes available APIs. A specific processor receives a Java source code or compiled bytecode as the input, and then outputs some files (usually. java files ). This means that you can use apt to dynamically generate code logic. Note that apt can only generate new Java classes and cannot modify existing Java

Http://www.gracecode.com/posts/2973.htmlunderstand the average processor load in Linux Original article: Http://blog.scoutapp.com/articles/2009/07/31/understanding-load-averages 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 averag

Users need to assemble a computer, the first need to build a set of suitable for their own computer configuration, if the configuration is not suitable for their own affirmation is not, for example, they like to play a large game, and configure the performance of the game is not strong, large games will play up to compare cards, so want to play Computer configuration is not difficult to build, as long as the computer hardware with each other to ensure compatibility between the hardware, which i

access process cannot be 0. Conversely, if va[31:25] equals 0, the address VA to be accessed is within the process's own address space, so a process context switch is made to convert VA to MVA, where the PID of the above formula is the PID number of the process. FCSE Programming Interface: The ARM processor uses the C13 register of the CP15 coprocessor for FCSE functions, and the C13 register is described in section 4th, "CP15 Register Introductio

Label:Preface: One day to do performance testing, encountered a page of data extraction, at first thinking about using regular expressions are not extracted. Later carefully think about the wrong, a single extraction seems to be able to do, the dynamic variable number of extraction, but also splicing, it seems to write, even if it can be written to estimate is disgusting death. Look carefully, this is not the database inside the thing? directly from the database can not be finished. After searc

the Hardware Management Console (hardwareManagement Console. 2. Problem Solving: After introducing the concepts of "slot" and "lpar", how can we check the number of slots or lpar of the current machine? First of all, we need to know that lpar has many applications on Minicomputers, and is rarely used on x86 servers. To view the number of slots, run the following command: [Root @ compute-30-02 ~] # Lscpu | grep "CPU socket" CPU socket (s): 2 Command to return the result. The number of slots on t

1 PrefaceWhat is Apache Nifi? The Nifi website explains the following: "An easy-to-use, robust and reliable data processing and distribution system". In layman's terms, Apache NiFi is an easy-to-use, powerful, and reliable data processing and distribution system designed to support data routing, transformation, and system mediation logic for highly configurable indicators.To be clearer about what Nifi can articulate, the following is a brief introduction to the Nifi architecture, as shown in.Acc

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

Processor scheduling and deadlock hierarchy of processor scheduling 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. 1. Work and work steps Job: A broader concept than the program, not only contains the usual
