transmitted from inside the computer to the output serial data stream. A serial that is external to the computerThe data is converted to bytes for use by devices inside the computer that use parallel data. In the output serial data stream, add theParity bit and parity with the data stream received from the outside. Add a start-stop flag to the output data stream,And remove the start-stop flag from the receiving data stream. Handles interrupt signals issued by the keyboard or mouse (keyboard and

Even after four years of study in Wuhan, I feel that Wuhan is incomparable with Beijing in many aspects, such as city construction and quality. However, there is one aspect that Beijing envy, that's the speed of public transportation in Wuhan! Even when I see traffic congestion in Beijing, I miss it even more ......Take the bus 521 and catch up with another 521. At that time, some people reminded us to pay attention to safety. As a result, the driver

The message bus and activity system penetrate into the Linux desktop-general Linux technology-Linux programming and kernel information. The following is a detailed description. D-BUS is a promising message bus and activity system that is starting to penetrate into Linux®Desktop. Understand the reason for creating it, its purpose, and development prospects. 　　 D-

The overall solution of a recent project was designed as a distributed system, so it struggled with the CAN bus or RS485 communication. Therefore, I searched some documents about RS485 and CAN bus on the Internet. In addition to further understanding of RS485 communication characteristics, I also learned the characteristics of CAN bus and its comparison with RS48

registers, in the main device shift pulse, data by bit, high in front, low after, for full-duplex communication, data transmission speed overall than the I2C bus faster, the speed can reach the Mbps level. SPI has four working modes , depending on clock polarity and clock phase. 　　 Clock polarity has high and low poles:1, the clock low electricity peacetime, the idle Time Clock (SCK) at the low level, tran

Last night, I started to check the LCD and found that the front bus was not very well mastered. Later I summarized the reasons: First, I understood the bus principle very early, and second, there was no big routine during bus learning, third, it was just returned from the Dragon Boat Festival holiday and it was not in the status. Forget it. If you don't have a re

From: http://blog.csdn.net/flowingflying/article/details/5411124 The D-bus method is very important in mobile phone operating systems, including Linux-based operating systems such as maemo and moblin. It is estimated that andriod is also widely used. For more information about D-bus, see:Http://www.freedesktop.org/wiki/Software/dbusThere is also a large amount of learning materials on the Internet.Http://

Since the introduction of PCI bus, its unique characteristics have been favored by many vendors, which has become the mainstream of computer extension bus. At present, many domestic technical personnel have the ability to develop PCI bus interface equipment. However, the PCI bus programming technology, that is, the ope

FSB--front Side Bus (FSB) is the bus that connects the CPU to the North Bridge chip. Choose the motherboard and CPU, pay attention to the two collocation problem, in general, the front-end bus is determined by the CPU, if the motherboard does not support the CPU required front-end bus, the system can not work. That is,

Keywords: PCI bus configuration space Operating SystemSince the launch of PCI bus, it has been favored by many manufacturers with its unique characteristics and has become the mainstream of computer extended bus. At present, many technical personnel in China have the ability to develop PCI bus interface equipment. Howe

Bus Standard: It can be regarded as a standard interface between the system and each module, module and module.There are currently the following types:1.ISA, using a separate CPU bus clock, is IBM in order to adopt a full 16-bit CPU and launched. Thus the CPU can use a higher clock than the bus frequency, which is advantageous to the CPU performance improvement.

Need to rent a house in a new place or buy a house, an important consideration is whether the traffic is convenient, I rent the house when I would like to know from the bus station around me, can not transfer to where, I had this demand after the Internet search, and did not find similar features, and the trouble is, Baidu map the most basic API also does not show the interface of multiple lines at the same time, so only with the help of Baidu map ove

1) Overview Bus is a simple system that uses its own threading mechanism to distribute messages from a pipe thread to an application. The advantage of the bus is that when GStreamer is used, the application does not require thread recognition, even if GStreamer has been loaded with multiple threads. Each pipeline contains a bus by default, so the application does

1. Introduction D-bus is an advanced interprocess communication mechanism, which is provided by the Freedesktop.org project and is issued using the GPL license. The main purpose of D-bus is to provide communication to the process in the Linux desktop environment while delivering the Linux desktop environment and Linux kernel events as messages to the process. The main probability of D-

Manager's bus theorySource: students major professional site Author: studa Public Bus is a transportation tool for the most people in a big city. Because of its universality, buses are mainly practical and cheap, and people love and hate them. Many bus-related metaphors and theories have been circulated among the people. Some of them are very interesting and some

With the rapid development of related technology and China's communication market, the main network of the mainstream SDH equipment rate has risen to 10G, and 2.5G SDH transmission equipment by these more high-end equipment extrusion, network application level began to move down, gradually into the edge layer, replacing the original in the edge of the 622M equipment. On the other hand, with the rapid growth of the bandwidth demand of data and Internet service, more and more requirements are put

At present, many companies have proposed new types of computer high-speed bus, such as the Arapahoe bus standard and hypertransport technology. However, the protocols are not compatible with each other and there is no unified standard. As a traditional universal local bus, PCI bus still occupies the mainstream PC marke

The principle of communication is to generate the signals required by the I²c-Bus protocol to transmi

Overview of AMBA, AHB, and APB bus Author: adamzhao Date: 19:33:00 About AMBA with the development of deep sub-micron technology, the scale of Integrated Circuit chips is growing. From Time Series-driven design method to IP address reuse-based design method, digital IC has been widely used in SoC design. In the SOC design based on IP address multiplexing, on-chip bus design is the most critical issue. T
