| With the coming of the Post-PC-Era, more and more products today have been embedded with computers. The Post-PC-Era can refer to the era in which everything is embedded. Computers will penetrate through every pore of our life. The embedded-system will become the mainstream of Post-PC-Era.To occupy the spacious embedded system market, the designers of embedded system are obliged to design more sophisticated products and shorten the cycle of R&D. Traditional embedded systems usually refer to the systems which do not rely on a PC platform, they are designed in a special way. However there are various standard PC components in the market which are often cheaper than the corresponding customized components. So utilizing standard PC component but not customized components maybe is a more sensible selection to shorten the cycle of R&D. Some embedded system designers are tending to use embedded PC as the platform of their products. To do this, they can take advantage of the price and performance superiority of PC, at the same time there many excellent software development kits they can use.The so called embedded PC can refer to a PC which is a piece of product or the component of a product. The product embedded with a PC can take advantage of the various wit functions of PC; embedded PC can be integrated into all the products. The popularity of desktop PC contributes much to the rapid development of embedded PC. Because the widely use of desktop PC, more and more people are familiar with it. With the increasing performance of PC and the sharp decreasing of its price, embedded PC is penetrating through every field of Post-PC-Era.The paper introduces the concepts of embedded-system and embedded-pc, following by the introduction of an embedded real-time operating system-eCos which is the abbreviation of the embedded configurable operating system. Based on the features of embedded-pc, the paper places its emphasis on the support of embedded-pc that eCos can provide, and analyze the shortages of eCos and the feasibility of atonement. Aim for the shortages of eCos on supporting embedded-pc, the paper discusses 3 main problems we have resolved in detail at the end of the paper. |
