AbstractAbstract Abstract Abstract Under the requirement of inteUi2ence of the automobile，the communications，and SO on，both the science and techenology of the embedded system develop very lastly．In our countrvpeople are studing the key techenologies both in hardware and software of the embedded system，and have designed a number of ASICs and embedded operating systems．For onr country,it’S a good opportulity to catch up with the advanced countries in the field of embedded system． eCos(embedded Configurable operating system)is an open SOU[CO，configurable， portable，and royalty-free embedded real-time operating system．It has full—featured， flexible，configurable，real time embedded kernel，together with full·featured TCPfIP protocol stack．These advantages lead to a more and more widely usage．This thesis describes these characteristics and then analyses its kernel and porting process． ColdHre is serial of MCUs，with high performance，low power consume,low cost． These MCUs are used in many fields．such as automatic,consunle electronic,and∞ On．Introduction of ColdFire architecture and its work mode is present in this thesis． Knowledge of porting eCos to these platforms with ColdFire MCU is the main results． This thesis proposes general steps to porting eCos onto platforms with ColdFke MCU， and solutions for problems in porting．As an example，eCos lmve been ported to MCF5208EVB,a convenient platform for evaluating many of the capabilities of the MCF5208 MCU,followod with measurement of this poaing． As眦application of the porting,the physical layer of IEEE 802．15．4 Was realized on this platform MCF5208EVB，also with the evaluation． This thesis can guide the porting of eCos on to platforms with ColdFke MCUs，and also is the basis of realization of IEEE 802．15．4 or Zigbee On these platforms for the ￡u_rthcr development． Keywords：Embedded system，eCos，ColdFire MCU，Porting,WPAN II 图表目录图表目录图表目录图表目录图2—1 eCos组件仓库路径结构。6 图2—2 eCos组件定义结构．．7 图2-3 eCos一个示例配置的组件层次结构。7 图2．4 eCos异常处理流程【13】。8 图2
