The temperature dropped sharply, everyone began to add clothing cold, micro-blog on the "cooling" concern data straight up. Finally have the breath of winter, the Christmas tree on the street, add a lot of festive festive. In the countdown to the 2010 days. Drive life in the end of 2010, to bring you online version of the hardware detection function, so that more users, without the threshold of detection of their own computer configuration. Let's tak

The purpose of adding hardware services to the Android system is to enable app-tier apps to access hardware services through the Java interface. So how does app access the hardware services provided by the application frameworks layer through the Java interface? In this article, we'll add a built-in application to the Android application layer, which uses the Ser

1. IntroductionThere are two clocks of hardware clock and system clock in Linux. The hardware clock is the clock device on the motherboard, which is usually the clock that can be set on the BIOS screen. This time there is battery-powered maintenance on the motherboard, if the motherboard battery is exhausted, if the power outage, restore to the factory settings. The system clock refers to the clock in the k

Introduction: PAPI is a set of local interfaces for accessing the processor hardware performance counters, and using this interface to monitor the hardware execution characteristics of the Java program will help to discover the root cause of the program performance problem on the hardware layer of the computer system. This paper introduces the important concept o

In a computer, system resources include the interrupt request (IRQ) line, direct memory storage (DMA) channel, input/output (I/O) Port, and memory address. When the same system resources are allocated to two or more devices, a hardware conflict will occur and conflicting hardware devices will not work properly. The following methods can help you solve hardware co

If you develop a performance-intensive 3D game, you ' re always looking for ways to give users richer graphics, higher frame Rates, and better responsiveness. You also want to conserve the user's battery and keep the device from getting too warm during play. To the optimize of these areas, consider taking advantage of the hardware scaler that's available on almost AL L Android devices in the market today. How does it works and why do you should use i

In H.264 decoder, the implementation of cabac hardware accelerator H.264 has two kinds of entropy encoding solutions: one is context-based adaptive variable-length encoding developed from the variable-length encoding solution, and the other One is context-based adaptive binary arithmetic code cabac developed from arithmetic coding. Compared with cavlc, cabac can save about 7% of the bitstream, but increase the computing speed by 10%. . When decoding h

Hardware interruptions frequently consume CPU resources. If there is a way to allocate a large number of hardware interruptions to different CPUs (cores) under multi-core CPU conditions) processing clearly balances performance well. Currently, multiple CPUs, multiple NICs, and multiple hard disks are not supported on the server. If the NIC can be interrupted, one CPU (core) is exclusive) if the disk IO inte

Most software-only firewalls are based on the PC architecture and may adopt optimized OS as their operating platforms. The features are as follows: good scalability, adaptability, easy upgrade, and far lower cost than the hardware-based firewall. Most hardware-based firewalls use ASIC, and do not require OS support. They feature fast speed, good stability, and higher security factor than software firewalls,

On a computer, system resources include interrupt request (IRQ) lines, Direct memory storage (DMA) channels, input/output (I/O) ports, and memory addresses. A hardware conflict occurs when the same system resource is assigned to two or more devices, and the conflicting hardware devices will not function properly. The following methods can help you resolve hardware
