Open publisher page 2 citations

Abstract

Task synchronization for VxWorks to access critical resource mutually is applied.Binary semaphore is an important method to realizing synchronization in VxWorks.The result consistent is improved when tasks are executed.The paper introduces binary-semaphore,researches the techniques of solving mutex and synchronization,and presents the program frame in X-data gathering system,which use semaphore to control the data gathering,stroing and quering tasks of 8-receiveing channels sharing the buffer.
