| Abstract: | The uOSEK,an embedded real-time operating system for vehicles,is designed based on the specification of OSEK/VDX.The main design ideas of the system are presented,covering starting,task scheduling and task management.Finally through its implementation on Freescale HC08 microprocessor,the real time performance and memory requirements of the system are evaluated.The results show that the system on an 8-bit microprocessor has good feasibility,strong real-time performance and relatively low memory requirements. |
