Abstract

The invention discloses an inter-process communication method. The method is applied to a computer system. The method comprises the following steps: writing data to be transmitted between a sending process and a receiving process into a register block and a stack memory of a first execution entity of the sending process according to a calling agreement; writing the address of the stack memory and a first value representing the data volume of the data in the stack memory into a register group; and copying the data to be transmitted from the stack memory of the first execution entity to the stack memory of the second execution entity through the second execution entity receiving the process according to the address of the stack memory and the corresponding first value. Data are transmitted through the register block and the stack memory, the communication performance of the IPC is improved, in addition, the invention further provides an inter-process communication scheme of the multi-stage IPC sequence, the intermediate process of the multi-stage IPC sequence only needs to forward the address and the data length of the memory block, cross-process copying can be achieved, and the communication performance of the multi-stage IPC is improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method and device for inter-process communication. Background technique [0002] With the development of computer technology, the communication requirements between multiple processes and between multiple processes and the same process increase. Currently, a send (send)-receive (recv) semantic model based on a communication channel is usually used to realize the sending and receiving of inter-process messages. [0003] The kernel provides an interprocess communication (IPC) service through a communication channel, and the communication channel is created by the receiving process and authorized to the sending process. The sending process prepares the data to be sent in the user state according to the requirements, and then the sending process and the receiving process use the memory block (buffer) to send and receive the data respectively. During the sending process...
