In the last two articles, we described how to write drivers for the hardware of the Android system, including how to implement kernel drivers in the Linux kernel space and implement hardware abstraction layer interfaces in user space. Both are implemented to provide hardware access to the upper tier, providing hardware
Enable hardware acceleration What does it mean to play games and watch movies faster or slower after you enable hardware acceleration, which is turned on by default and how to turn off hardware acceleration. In short, hardware acceleration is the use of hardware modules to

A typical manifestation of hardware resource conflicts: When you add new hardware or after adding new hardware, the system often crashes and black screens for no reason; when you start, the system enters the Security Mode for no reason; the sound card and mouse cannot work normally or go on strike. When you press and hold the Alt key and double-click my computer

Specification of hardware development documentation 1. Hardware Requirement Specification The hardware requirement specification describes the hardware development goals, basic functions, basic configurations, main performance indicators, and operation environment. Environment, constraints, and development funds and pr
Android starts with 3.0 (API level 11), supports hardware acceleration when drawing view, takes advantage of GPU features, makes drawing smoother, but consumes more memory.To turn hardware acceleration on or off:Because hardware acceleration itself is not perfect, Android offers the option to turn hardware acceleration
The first time to do intelligent hardware, without all kinds of pit, but in this process is also gradually explore a more intuitive intelligent hardware abnormal case to check the method, through this method I combed out of the exception than the engineer reported to me a comprehensive, pro-test available, you may wish to try. Compared with the software, intelligent ha
Understand and use Linux the hardware abstraction layer HAL Author: Liu Xuhui Raymond Reprint please indicate the source Email:colorant@163.com blog:http://blog.csdn.net/colorant/ Home: http://rgbbones.googlepages.com/ Ashamed to say that, based on the arm of the platform for such a long time, has been busy in the kernel, very little understanding of the development of the application-related, and did not contact the HAL and Dbus. Because the top o
The MINI2440 Development Board uses the =2k of 8bit,256m blocksize= 128k,pagesize Nandflash.Broadband is 8bit, by s3c2440 datasheet know hardware production of ECC is 4byte.s3c2440 Hardware ECC Operation Flow:1. Read the ECC data produced by the hardware in the NFMECC0 register first.2. After processing the read-out ECC data, write the NFMECCD0 and NFMECCD1 regis
In the Android Hardware Abstraction Layer (HAL) Overview and Learning Plan article, we briefly describe the ways in which Android systems write drivers for hardware. In short, hardware drivers are distributed on the Linux kernel, and on the other hand, in the hardware abstraction layer of user space. Next, writing a Li
Source: Computer newspaperThe hardware firewall is an important barrier to ensure internal network security. Its security and stability are directly related to the security of the entire internal network. Therefore, routine inspection is very important to ensure the security of the hardware firewall.Many of the hidden risks and faults in the system will appear in one way or another before the outbreak. The

Overview: use hardware configuration manager to collect hardware configuration information for client devices in an enterprise. To collect the hardware list, you must enable the hardware list settings on the client. After you enable the hardware configuration and
There 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. The system clock refers to the clock in the kernel. All Linux-related instructions and functions are programmed to read the system clock. Because there are two different clocks, there is a difference between them. When Lin

Article title: Relationship between Linux embedded systems and hardware platforms. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. I. Linux Embedded System An operating system is a software running on a computer. its main task is to manage system resources on the computer and provide users with interfaces to use
Description of UseThe Hwclock command, which is the same command as the Clock command, is used primarily to query and set the hardware clock (query and set the hardware clock (RTC)). Rtc=real time Clock, which is the hardware clock. There are two kinds of clocks, such as hardware clock and system clock, in Linux. The
9.4 Batch processing data Typically, only a limited number of persisted objects are stored in the cache of a Session object, and the session object is closed when the session object processes the transaction, releasing the memory occupied by the session's cache in a timely manner. Bulk processing data refers to handling large amounts of data in a transaction. The following program batch updates the age field for all records in a Customers table that
