kernel, and graphical user interface (or GUI ). In this article, we will focus on some basic concepts related to these three layers, and gain an in-depth understanding of how the boot loader, kernel, and file systems interact; it will also look at part of the many options available for file systems, guis, and boot loaders. Bootstrap loaderThe bootstrap loader is usually the first piece of code executed on any hardware. In conventional systems such as desktops, boot loaders are usually loaded in

Abstract factory pattern metaphor It is essential to catch up with girls. McDonald's chicken wings, French fries and KFC's chicken wings and French fries are what girls like to eat. Although the taste is different, whether you take girls to McDonald's or KFC, just say "two chicken wings and two packs of fries" to the waiter. McDonald's and KFC produce chicken wings and chips. Factory. This process is the abstract factory mode. Abstract factory p

company, the full name means Advanced RISC Machine. Founded in November 1990, the company is a joint venture between Apple Computer, Acorn Computer Group and VLSI technology. Acorn once launched the world's first commercial single chip RISC processor, and Apple Computer was hoping to apply RISC technology to its own system, the new arm of the microprocessor standards came into being. In the late 80, the semiconductor industry in the early 90 industry chain just appeared division of

-called "black film", there are basically two kinds, one refers to Samsung, Toshiba, Hyundai and other manufacturers to eliminate the defective products, the second refers to the market recycling of second-hand flash chips. As the chip manufacturers in the production of flash chips, the wafer production is graded, can be divided into 99% capacity, 97% capacity, 93% capacity and so on. Grades below 93% capac

launched a UltraSPARC based on dual-core architecture and PA-RISC chip. Only because these products are based on the UNIX architecture, but also high prices, so there is no large-scale access to pervasive applications. Later in 2004, AMD and Intel unveiled their dual-core plans, and for the first time since 2005, they have been supplying dual-core products. Of course, the two companies have launched dual-core processors dazzling-including AMD launched dual-core Opteron server chip and Athlon

the knowledge of memory brand About the memory of the brand and the market, many people's understanding of the misunderstanding, that is, often the production of memory chip manufacturers and real production of the memory of the manufacturer to confuse. We usually say Hy and other names are the production of this memory chip manufacturer name, rather than the actual production of the memory of the manufacturer. Is it true that the big companies like Samsung and Hyundai do not actually produce m

! I'm different. Six, hardware configuration It's mainly the SOC chip configuration. In the handheld device era, the biggest difference with the PC era is that the PC era chips are owned by the double giants, they are responsible for from design to manufacturing, you only need to buy, and the handheld device era, or post-PC era, only arm an oligarch, it is only responsible for design. You buy the drawing back, deep processing, and then make or contact

number of 400-500. In October 2010, Qualcomm acquired Iskoot,iskoot expertise in mobile access Internet services, such as social networking, consumer email and IM products, and is expected to integrate Iskoot technology into the brew MP to enhance the platform's Internet service capabilities. positioning Brew offers a vertically integrated solution for the development, release and monetization of applications based on Qualcomm Chip handsets, including compatible

'); setlocale (LC_ALL, 'de _ at'); // set the time zone in Windows to setlocale (LC_ALL, 'Spanish _ Mico '); setlocale (LC_ALL, 'German _ Austria '); LocalizationText message In order to implement multiple languages, many programs save all prompts and text information to a lang array, and then use local settings to call lang languages in different regions to implement multi-language versions. As shown below: $messages = array ('en_US' => array( 'My favorite foods are' =

process the input and output correctly.Therefore, it is very convenient to perform some simple processing of mapreduce scripts. In this example, we want to calculate whether a Texas hold'em player wins. The algorithm is: If the card is discarded or the winning chip is NULL, it will lose. If you have a winning edge pool or a base pool, you may not necessarily win. Use the base pool + edge pool chips-the number of bets. If it is greater than 0, it will

The stm32 standard peripheral library is a peripheral driver for the entire series of stm32 chips. With it, we can greatly accelerate the development of stm32.First, download the latest stm32 standard peripheral library from the website of st. The latest version is v3.5.0.

suggested that we implant chips in their "brains" so that they can be shut down once they have bad thoughts. But some people also say, Why are different robots integrated? This is what Brooks thought. He was the head of the AI lab at the Massachusetts Institute of Technology. "In the past 50 years, we will be able to see fundamental changes in the human body through genetic transformation," he said. The human population will change in ways that peopl

it is in the application of the switch and analog amplification, the selection of this resistance is not the head. There is not much to say about working in the linear range. Here we discuss the use of transistor as a switch, so we only talk about the switch mode. Find the data of a TTL device and simply look at the last level. The internal load resistance varies depending on the drive capacity and speed requirements. The low-power resistance value is large, and the fast resistance value is sma

About I2C and SPI bus protocols Iicvs SPI Currently, in the low-end digital communication application field, we can see IIC (Inter-Integrated Circuit) and SPI (serial peripheral interface) everywhere. The reason is that these two communication protocols are very suitable for close-range and low-speed chip communication. Philips (for IIC) and Motorola (for Spi) have developed these two standard communication protocols for different backgrounds and market needs. IIC was developed in 1982 to provid

Troubleshooting of document structure: my mom's list contains dozens or even hundreds of recipes. If a fatal error is generated, the troubleshooting will be very difficult-you will search for the missing token line by line. If several layers of nesting are applied, it will be very difficult to invent the error. Troubleshooting of document structure: my mom's list contains dozens or even hundreds of recipes.

' requirements for audio systems are getting higher and higher. For example, no matter how many people are talking, the audio receiving system only receives my own voice, and the rest of the voice can be filtered out. When I talk to each other, I not only cannot hear the echo of the line, but also hear more real surround sound effects. To meet these high-definition audio requirements, WM8958 must be used in combination with AudioPlus series products of ousheng, such as audio MEMS Microphone Arr
