[0055] Please refer to figure 1 , the message queue shared memory of the present invention is made up of two independent parts, and a part is used for the message queue information of management, establishes independent index ID, memory reads, writes the pointer, adopts independent semaphore control synchronization; The other part is used for communication The message queue of the process. All communication processes use a common semaphore to control synchronization. Each process has an independent message queue with characteristic values. The messages are convenient for message classification management and improve access efficiency. The read and write pointers of the message queue are easy to distinguish Whether the message has been processed.

[0056] Considering the consistency of message processing methods, the same message structure is used in the management message queue and the message queues of each process. The structure needs to have some key flag information for in...

Abstract

The invention discloses a device and a method for optimization of inter-process communication of an embedded operating system. The method comprises the following steps: initializing a management process to determine operation information of system equipment; initializing a characteristic information structural body and the equipment; establishing a real-time memory library; establishing a channel process message sharing memory space, a management process message sharing memory space, the semaphore of the channel process message sharing memory space and the semaphore of the management message sharing memory space; mapping the channel process message sharing memory space and the channel process characteristic information structural body; establishing channel processes according to the operation information and transferring a management message to the corresponding channel process; entering the management process, setting the semaphore of the management message, and reading the management message which is less than or equal to the semaphore of the management message. According to the device and the method, the problems of useless message transfer and low message processing efficiency existing in a message transfer mechanism established by using the sharing memories under the condition of communication among multiple processes of the embedded operation system are solved.

Description

technical field [0001] The invention belongs to the field of computer communication, and in particular relates to a device and method for optimizing inter-process communication of an embedded operating system. Background technique [0002] Traditional embedded computer communication technologies can use pipes, FIFOs, message queues, inter-domain sockets and shared memory methods. Because shared memory has the characteristics of simplicity, flexibility and high efficiency in operation, it is widely used in inter-process communication of embedded computers. Real-time library management of embedded computers, inter-process communication queues and other operations can be realized through sharing. Using the message mechanism of the shared memory can solve the work of mutual conversion between communication interfaces when the embedded computer is used as a communication management machine, especially in the process of mutual conversion between low-speed interfaces and high-speed...
