| Along with the computer technology in the middle of each kind of electronic products' widespread application, the embedded system takes one kind of practical, the highly effective computer system, obtains the widespread development and the applications.At present the embedded product had already formed the very widespread market, for both supplier and the consumer, how to provide high performance, low cost, low power loss product appears to be especially important. "Low cost" enhanced the product competitive power, "the high performance" had guaranteed the product vitality, is our large-scale manufacturing industry development inevitable trend.Devotes in studies the renewal, is better, cheaper embedded products, satisfing the market development and the competition need is very urgent.This system uses 16/32 RISC processor S3C44B0X (ARM7DMI), which provids high performance-to-price ratio and the high performance micro controller's solution for the low cost computer system.ARM has the influence microprocessor manufacturer in recent years in the embedded system, the ARM design is suitable in the low power supply system.The very prominent in the performance and the technical aspect, makes it become the ideal choice for embedded system. The embedded technology application can realize "the miniaturization" and "the low cost" goal.In order to reduce software's cost: This system uses ucLinux operating system,μcLinux is stable,which can run in the S3C44B0.In this system's hardware part: Realizes the low cost computer system's main board, the keyboard, the mouse, the LCD monitor and the USB connection, as well as the computer monitor connection (computer monitor connection and ARM LCD monitor connection is not the same)and Related hardware parameters.In this system's software part: Embedded systems software development by way of cross-compiler. This article discusses in detail to guide the allocation of low-cost computer systems U-BOOT process and the making of the operating systemμcLinux. |
