ARM9

The ARM9 family processor is ARM's UK mainstream embedded processor design, including ARM9TDMI and ARM9E-S series. Outline Mobile phone applications, for example, 2G phones only provide voice and simple text messaging, and the current 2.5G and future 3G mobile phones in addition to providing these two functions, must also provide a variety of other applications. Include: (1) wireless network devices: mobile Internet, e-mail and other location based services and other functions; (2) PDA function: with the user operating system (Windows CE, Symbian OS, Linux, etc.) and other functions; (3) high Performance features: audio player, video phone, mobile phone games. 2.5G and 3G applications ARM9 has been fully replaced ARM7. Because new features to meet the ARM9 new needs while reducing product development time and reduce development costs. Processing capabilities A new generation of ARM9 processor, the new design, the use of more transistors can achieve more than twice the processing power on ARM7 processor. This capacity increase is reduced by increasing the clock frequency and instruction execution cycle to achieve. (A) the increase in clock frequency: ARM7 processor with 3-stage pipeline, while the ARM9 5-stage pipeline. Increase in pipeline design to improve the clock frequency and the parallel processing capabilities. 5-stage pipeline can be assigned to each processing instruction five clock cycles, a clock cycle at the same time every five instructions in execution. Under the same processing technology, ARM9TDMI ARM7TDMI processor's clock frequency is 1.8 to 2.2 times. (B) instruction cycle improvements:
 Instruction cycle to improve processor performance improvements for the great help. Performance level of increase depends on the instruction code execution overlap, which is actually the program itself. For the most advanced language, in general, the performance increase of 30 percent. Instruction 1, loads n stores instructions and directives
 Cycles of the most obvious improvement is loads instructions and stores instructions. Both from ARM7 to ARM9 instruction execution time is reduced by 30%. Instruction cycle is due to reduction in both processors ARM7 and ARM9 within the two basic micro-processing caused by the different structures. (1) ARM9 has separate instruction and data memory interface, which allows the processor to fetch the same time and read and write data. This is called a modified Harvard architecture. The ARM7 only data memory interface, it is also used to fetch and data access. (2) 5-stage pipeline to introduce a separate memory and write back to the line, were used to access memory and write the result back to register. More than two loads to achieve a complete cycle of instructions and stores instructions. 2, interlock (interlocks) technology When the instruction data needed because the previous instruction is not executed but is not ready will have a pipeline interlock. When the pipeline interlock occurs, the hardware will stop the execution of this command until the data is ready. Although this technology will increase the code execution time, but for the designers of the early great convenience. Compiler and assembler programmers can code in order to redesign or other methods to reduce the number of pipeline interlock. 3, branch instructions ARM9 and ARM7-branch instruction cycle is the same. And ARM9TDMI and ARM9E-S did not predict branch instruction processing.

Google Talk

Google Talk is Google's IM tool, in addition to IM functions, also added Viop function, the interface fresh and generous, you can link directly to Gmail, check the message received.IntroductionThe introduction of Gtalkr is a full Flash, Google Talk. Gtalkr also built-in Yahoo! Maps! As long as a Gmail account, you will be able to enjoy this RIA brings experience and you can download Gtalkr Notifier, whenever a new Google Talk or Gmail e-mail message, he will be prompted to you.Specific descriptionGoogle Talk is Google's instant communications, referred to Gtalk. It can be computer to computer text chat and voice call is connected. This will further intensify its Google and Yahoo, Microsoft and America Online in the competition.
Google site has launched instant messaging software download page provides windows platform client software. Another gadget online using a variety of platforms in use. Google claims that the software "allows you and your friends anytime, anywhere in the world of free calls, send instant messages." Google's instant messaging software and its e-mail service, Gmail has been combined. Gtalk chats can be automatically saved to their Gmail web mail, you can read anytime, anywhere in the past, this is a beloved feature.Industry observers Google instant messaging software innovations are interested, this is Google to attract tens of thousands of other instant messaging users to switch to its own software key.
 Google Talk is an advantage is that it can integrate with other instant messaging software and services to connect. Because Google Talk is based on the Jabber open-source standard, which allows users and other systems connected to instant messaging, such as Apple's iChat, GAIM, Trillian Pro and Psi.Currently, Google Talk can make use of third-party software to run on multiple platforms. If you want to make voice calls, users need a microphone and speakers. Aggregation of Google Talk on Gmail by installing a plug-in on Mac and PC video chat.
Search Engine Watch's Danny Sullivan, editor, allowing users to stay on your pages longer makes sense for Google. He said: "Ultimately, I consider it to be a portal, a portal site, users can access from here to the network, users want to get some in this entrance site services, instant messaging is a service they want."However, in the instant messaging market, Google is facing a large number of competitors, such as America Online's AIM, Yahoo Messenger and Microsoft MSN Messenger, the instant messaging software, users will no doubt use the new communication software hesitant.Google Talk users can not use this software with MSN Messenger or Yahoo Messenger users to communicate, because they are different communication protocols.
 After using the Google Talk, Sullivan sound quality of this software to the score, but, Google Talk and chat with the lack of Contents Index text search function.
 Sullivan said: "If Google want to impress the user, this is best able to change over."AIM and MSN Messenger are able to voice chat.
A Jupiter Research analyst David Card said he Google's instant messaging software to understand the reasons for that, but Google's instant messaging software for its ability to attract enough users skeptical.
"Web search", author John Battelle said: "instant messaging software to connect users to a platform, which is the Google Desktop software you want to achieve a goal. Internet voice calls is another to achieve this goal way. "

Morning twilight far less effect to good practice

The initial exercise to take a large amount of exercise, high-intensity exercise
Suddenly a lot of movement, the body is difficult to adapt, there will be severe fatigue, aching muscles or cause old and sick, can also cause tendon, muscle strain, is difficult to adhere to long-term exercise. Correct training methods are: small amount of exercise, the small size, simple operation began, so that the body has a process of adaptation, this process also known as fatigue period, about two weeks, then gradually increase the amount of exercise, plus substantial, action should be slowly to easy to difficult.
The first time for exercise equipment to do all the instruments are
In fact, there is no need to instrument every time a fitness do not fall over. You do not only take up a lot of time, and because of sudden excessive movement, too strong, there will be body aches, so difficult to maintain normal exercise. The correct way is to ask a fitness instructor, or according to their situation, formulate an optimal exercise program and a plan step by step to achieve your bodybuilding program.
Regardless of the choice of what sports are used to wearing a shoe
Different standards should be based on the selection of sports shoes. To focus on functionality, different projects in different sports wear shoes, to fit comfortable, air-cushion shoes to prevent shock, reduce joint stress, to the campaign to secure protection.
Morning twilight Enhancing than
In fact, the high cohesion of the morning's blood, the risk of thrombosis is also a corresponding increase in the peak of a heart attack. Instead, the evening is the ideal time for physical exercise, because the evening when the heart rate, blood pressure, most balanced, most fit exercise heart rate, blood pressure changes; evening smell, hearing, vision, touch the most sensitive to stress ability of the human body is the peak day ; evening the body's ability to resolve the thrombus to achieve the best level. Therefore, it should be evening than morning exercise is good practice.
Sweating only be considered valid exercise
Sweating do not sweat, can not be used to measure the movement is valid. The body's sweat glands varies, active and conservative sub-two, which is genetic. The first warm-up exercise in order to meet the follow-up is conducive to thrust, to avoid injury, warm-up certainly is not sweating.

Holoscreen

CLARO launched a never-before-seen display -- clear glass TV, called" Holoscreen". It is different from the present any television, is holographic technology and visual aesthetic of the perfect combination. Can be regarded as display technology revolution.

Call it revolutionary display, mainly because the television is the use of holography. You may display using holographic technology is still very strange. Here, there is a need for simple introduce the" holographic technique".

Holographic technique was first used in photography. It actually uses the light interference principle. Object unique optical information recorded in the photosensitive material, after developing after fixing, a hologram. This hologram is no image. If you want to see the image, is to make the light to reproduce. Reproducibility of the image and the original as like as two peas, as through the window to watch the scene outside. Moving the eyes can see objects of different side. Watch and the features of different distances, the effect better, and watching drama no two.

Holoscreen is to this principle is applied to television. See it behind the projector is equivalent to the optical information recorder, which display is used to display hologram. The entire screen is made of 10mm thick glass. 1.5m x 1.0m rectangular area. Outside of a transparent material covering the area greater than the display screen, a little older, as 610mm x 814mm. As can be seen from the chart of the whole Holoscreen accounted for relatively large area. It shows the picture is in the air.

It can accept all input format. From the television, DVD, video, personal computer to the notebook, can be used.

It has its unique characteristics. The transparent display can interact with the surrounding environment and a very good combination. As long as they are able to think of, such as wood, metal, stone, textiles, leather products. No matter what the environment, it can guarantee good brightness and clarity of the image.

With stereo sound and with the surrounding environment, the display, the home theater quality and promoted many. Read on to know its price is generally can not afford. A set of down to 25000 euros.

Vertical search

Vertical search is targeted at a particular industry professional search engine, search engines are broken down and extended, the webpage database is some kind of specialized information integrate a directional branch field, extract the needed data to be processed and then in some form is returned to the user. Relatively general search engines with large amount of information, the query is not accurate, not enough depth, put forward the new search engine service mode, through targeted to a specific domain, a specific group or a specific demand to provide some valuable information and related services. Its characteristic is "specialized, refined, deep", and with industry of color, compared to the general search engine information disordering, vertical search engine is more focused, specific and thorough.

Brief introduction

Vertical search engine is relatively general search engines with large amount of information, the query is not accurate, not enough depth, put forward the new search engine service mode, through targeted to a specific domain, a specific group or a specific demand to provide some valuable information and related services. Its characteristic is "specialized, refined, deep", and with industry of color, compared to the general search engine information disordering, vertical search engine is more focused, specific and thorough.

Vertical search engine and general webpage search difference

Vertical search engine and ordinary webpage search engine is the biggest difference is to webpage information in a structured information extraction, namely the webpage of the unstructured data into structured data extraction of specific information, such as webpage search is a webpage for the smallest unit, based on the visual analysis in the webpage webpage block block is the smallest unit, while the vertical the search is based on structured data is the smallest unit. Then these data are stored into a database, for further processing, such as: weight, classification, the last word, index to search the way to meet the needs of users. The entire process, data from unstructured data into structured data extraction, after deep processing unstructured and structured way back to the user.

Microsoft Research Institute, a technical expert once said:" the 75% content using the search engine". Vertical search engines birth is to greatly improve the search" recall" and "precision". Vertical search engine based on the industry in the field of information model and user model structured collection or organization, and provide more and more professional, personalized industry related services.

Application direction

The application of vertical search engine direction, such as the enterprise library search, supply and demand information search, shopping search, property search, talent search, map search, MP3 search, image search ... ... Almost all walks of life, all kinds of information can be further refined into various types of vertical search engine. An example would be easier to understand, such as shopping search engine, the whole process is as follows: grab the webpage, the webpage commodity information extraction, extract the name of commodity, price, description ... ... Even can be further subdivided into " brand, notebook models, memory, hard disk, CPU, screen, ... ..." Then the information for cleaning, to heavy, classification, comparison and analysis, data mining, finally through the word index provide users to search, through the analysis of mining to provide market reports.

Technology

Vertical search engine generally requires the following technology

1 search engine spiders crawl the Internet: the relevant webpage

2 webpage structured information extraction or metadata acquisition technology from the webpage: extracting structured data

3 word segmentation, indexing: storage and index data

4 data shows: as the stored data are not simple webpage data, need to consider according to industry demand for display

5 other information processing technology

Get up within an hour after eating breakfast will help to lose weight

During the holidays, will have dinner activities, although it is a good thing, but for ongoing weight loss of friends can be pinched together, you would think, if you eat not fat should have much good! In the face of the temptation of food can you hold?

If you can't help, then try the following to introduce how to eat not fat method.

Method: within 1 hours after waking up in the morning to eat breakfast

Harvard University researchers found, the morning after getting up to 1 hours after breakfast, can help you in a year effortlessly to lose 10 pounds. So breakfast can help us stable fast the new supersedes the old. At night, and can help to burn calories and muscle tissue growth, reduce the increase in abdominal fat hormone. In fact, eating breakfast and weight loss method!

Method two: put the tea snacks when can Qingchang

Tea can help weight loss, so every day, don't forget to drink a cup of tea, and stood up to relieve the fatigue of limbs, which can reduce the desire to eat, you won't just some things to eat. Especially for the holidays, home snacks are more people, appropriate to eat, and to drink tea to help control the heat, motivate yourself, let yourself less snacking desire.

Method three: do not put on the snack table

Holiday at home, people always like to do things in the sofa to watch TV, and watch TV while very like eat some snacks, watch TV while eating snacks, very easy to increase body heat. So don't in the tea table snacks, watch TV, do not have snacks may take, it doesn't want to eat. If you still want to chew something, then suggest that you eat fruit, but don't eat dessert high-calorie snacks.

Method four: after 9 p.m. do not eat any food

We sleep, organs are at rest, so that the consumption of heat capacity is reduced, if after 9 at night, before going to sleep and eat something, then these consumable heat will hoard in vivo, and transformed into fat, meat will be in your sleep time crept out. So after 9 pm will not eat any food.

Method five: eat a big meal should pay attention to details

In the order, the attention chooses not fattening foods, and easy to be lit and easy to grow food do not eat meat, fresh vegetables, fish, eggs and grains can eat. In addition, meat food week consumption not more than 3 ~ 4 times, recommended to eat poultry meat. If the fish instead of pork is better. In order to reduce food intake, is recommended in the meal before eating a bowl of nutrition is rich, low heat soup, vegetable soup, such as soup or egg soup can. It wouldn't be eating too much. Carbonated drinks and wine heat is relatively high, so try not to drink.

These are what you eat not fat method, even in the face of meal is also afraid of excessive intake of calories, is a very good control methods of heat.
