Mobile phone by virtue of the two basic functions of call and SMS, accumulated users, opened up the market. But the user's demand is endless, for handset manufacturers, closely follow the user needs, expand the function of mobile phones, is the opportunity is also a challenge.
1988 the first digital camera, listed in Japan. The key to digital cameras isphotosensitive Chip。 The original data camera, using theCCD Chip。 At the beginning of the 1990, NASA scientist Eric Fossum inventedCMOS sensor chip, smaller size, better photosensitive effect。 If you putCMOS sensors integrated into the mobile phone, then the phone can be combined with camera and camera functions
But things are not that simple, with the lens on the phone and CMOS sensor chip is only a start, then there are other problems to be solved. 1. The processing power of the microcontroller needs to be enhanced. 2. The operating system needs to add the appropriate driver, while improving the task scheduling mechanism. 3. Multimedia player, on the liquid crystal display (LCD) display photos, play video, while coordinating the sound of the speaker to play video synchronously. 4. Not only can store and display photos and videos locally on your phone, but also support networking to enable users to upload and download multimedia files.
In 1997, Silicon Valley engineer Philippe Kahn made the world's first mobile phone with camera function. And the camera phone was born at the same time, is his daughter. [7] Philippe the baby's daughter with a cellphone and forwarded it to more than 2000 friends and relatives, the first time in human history to shoot with a mobile phone and distribute it over a mobile network.
Since then, multimedia has become an indispensable function of mobile phones. In addition, the phone has added functions such as calendar, Notepad, calculator, music player and so on. and Java VMs to run programs written in J2ME. There is also WAP for accessing the Internet.
The mission of the second-generation handset is over, replaced by a third-generation handset, the so-calledfeature Phones (Feature phone)。 If you say,for the second generation of mobile phones, DSP is the core, the operating system is a supporting role。 Since feature phone, the function of the operating system has been greatly strengthened, the status has risen, from the supporting role to boil into the protagonist.
Feature phone's OS has a variety of options. Of these, Symbian has long occupied half of the feature Phone OS Market [8]. Once upon a while, Symbian OS hoot astonished, authoritative, is the dominant in the field of mobile phone operating system. For example, the Symbian OS is the operating system kernel (Kernel) in a strict sense. The same set of kernels can support a variety of GUI graphical interface, there was s60,moap and UIQ three kinds of GUIs, of which UIQ by Sony Ericsson (SonyEricsson) hot. As a handset maker, Sony Ericsson is a rival to Nokia. Legend, Nokia because Hate house and Wu, decided to suppress UIQ. In 2008, Nokia instructed Symbian Fundation to announce that Symbian OS will only support S60 a GUI in the future. [9] The neglected UIQ had no choice but to close the doors.

But in recent years, the mobile phone operating system market has been sharply volatile. The leading rebel is Apple's iphone OS, with the second shockwave coming from Google's Android, and Palm's webOS in the fun, see Figure 6. It was commented that
1. Symbian is too old to escape the fate of the twilight.
2. iphone Maverick, take the fine line, become a fashion vane.
3. Android slow, free open source, take the mass line, the future most likely to become the mainstream of mobile phone OS, to replace Symbian's leader status.
4. winmobile Pianan Corner, although not rich, but also well-off.
5. The hustle and bustle of webOS is a blip.
6. The future of rim rests with the strongman. If the independence of the hill, then the future bleak. Not only is it self-killing, but it's also likely to hit BlackBerry, the hot sell.

Where is the Nucleus OS? This is a corner forgotten by the market.

What causes the Nucleau OS to become yesterday's yellow? Figure 7 describes the various function blocks within the nucleus. The nucleus itself has unavoidable technical limitations, such as no virtual memory, and no kernel space and user space, and the system and applications run in the same space. This is not a big problem for feature phone, but it is very deadly for smart phone. Because if the application is not restricted, then the malicious program can exploit, gain control of the entire operating system, rogue. A typical case is a dead text message, and a malicious operation causes the entire operating system to crash.
But in 2000, MTK borrowed power nucleus OS, from a nameless IC Design House , Developed into the world's 20th biggest chip sales in the first quarter of 2009, see Figure 8. More importantly, MTK has subverted the traditional mobile phone manufacturing industry chain.
What did MTK do first? What are the technical advantages? What are the advantages of the business model? and listen to tell.
