【正文】 ， Linux內(nèi)核包含了你在任何操作系統(tǒng)所期望的所有特性。 TCP/IP connectivity。 support for 32bit ultrahighspeed CPUs。 and seemingly infinite capacity storage devices including CDROMs and hard disks. This is not the stuff of yesteryear’s “standalone” code, “rollyourown” kernels, or “plain old DOS”, No, those days are gone—forever. Then too, consider the rapidly accelerating pace of hardware and chipset innovation—acpanied by extremely rapid obsolescence of the older these two, and you can see why it’s bee an enormous challenge for mercial RTOS vendors to keep up with the constant churning of hardware devices . Supporting the newest devices in a timely manner—even just to stay clear of the unrelenting steamroller of chipset obsolescence–takes a large and constant resource mitment. If it’s a struggle for the mercial RTOS vendors to keep up, going it alone by writing standalone code or a rollyourown kernel certainly makes no sense. With the options narrowing, embedded system developers find themselves faced with a dilemma: On the one hand, today’s highly sophisticated and empowered intelligent embedded systems—based on the newest chips and hardware capabilities—demand noting less than the power, sophistication, and currency of support provided by a popular highend operating system like windows. On the other hand, embedded systems demand extremely high reliability(for nonstop, unattended operation)plus the ability to customize the OS to match an application’s unique requirements. The dilemma is: mon desktop operating system ( such as Windows ) are not well adapted to the similar equipment to the unique needs of embedded system. However, mercial realtime operating system, although designed to meet the embedded application reliability and configuration flexibility requirements, but due to their lack of standardization and inability to keep up with the speed of technology development, which is undesirable. Developers do? Fortunately, a new, exciting alternative systems have emerged: the open source Linux. Linux provides powerful and advanced system management facilities. A wealth of equipment support, the reliability and robustness, and extensive documentation has an excellent reputation. The best ( for developers ) is Linux not money are pletely free source code. Linux is it right? Like Windows is too large and the need for system resources too much, so can not meet the requirements of embedded system? Unlike Windows, Linux is a modular, and can easily be reduced into pact configuration, this configuration is almost almost DOS, even on a single floppy disk. In addition, because the Linux source code is fre
