基于共享内存的进程间通信在嵌入式软件测试中的应用

摘要

嵌入式软件测试中,数据问通信种类多、需求大、频率高,利用共享内存可使任意两个或多个进程间实现大容量数据的通信.数据格式由开发者自己内部组织.用Win32实现的共享内存易管理、易操作使用、互斥访问性好、实时性强、效率高.最终实现的测试平台结构清晰,操作便利.这也是软件项目模块化开发的最佳选择.%In embedded software testing,the communication between the data has a variety of sorts,high demand and is highly frequent.The use of shared memory can provide high volume data communication between any two or more processes. The programmers can org anise the data format by themselves internally. The shared memory implemented with Win32 environment is easy to manage, operate and use. It has good performance in mutual exclusion access and is good in real-time, and is highly efficient too. The final realised test platform has an explicit structure and is easy to manipulate. It is also the best choice for modularised development of software projects.
