Title: Design of Embedded E-Trade Information Terminal Based on ARM and μC/OS-II
Abstract: An e-trade information terminal is designed to meet the higher requirements for processing speed,real time capability and expansibility based on the 32 bit ARM chips of high performance as processor and combining with real time operation system μC/OS-Ⅱ.According to the resource requirements,the hardware structure of terminal is proposed.How to form an embedded development platform based on μC/OS-Ⅱ.In addition,the transplantation of μC/OS-Ⅱ in ARM microprocessor is discussed.A novel middleware module architecture is put forward,which increases reuse,transplant performance and expansibility.The division of task,assignment of software priority and the execution path of main program are determined.At last,some key technologies for implementing the information terminal are expatiated.The designed terminal runs reliably.
