Inter-process communication system based on domestic Loongson processor and operation platform

Abstract

The invention provides an inter-process communication system based on a domestic Loongson processor and an operation platform. The inter-process communication system comprises an atomic critical data read-write module, an atomic critical data read-write module and a memory barrier module, wherein the atomic critical data read-write module uses a processor to provide an end atomic read-write instruction and a memory barrier instruction to realize ordered writing and reading of data; the support service component module is responsible for receiving a communication end control instruction, creating a shared memory for managing inter-process communication and managing link connection between different communication ends; the inter-process communication end module runs in a specific process needing to complete the inter-process communication end in the instance, sends an instruction to the communication end, receives a sending end completion instruction of the support component, and stores a shared memory address created by the support component for the communication end in the communication end; and the inter-process communication interface module is used for writing or reading data into the created shared memory. The inter-process communication method based on the domestic Loongson processor and the corresponding macro-kernel operating system platform can be realized, and the concurrent inter-process communication performance during multi-process cooperation in the system is optimized.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to an inter-process communication system based on a domestic Loongson processor, in particular to an inter-process communication system and an operating platform based on a domestic Loongson processor. Background technique [0002] At present, the domestic Loongson processor and the corresponding macro-kernel operating platform are gradually being widely used in many different application fields. Considering that domestic Loongson processors are independently developed by Chinese research institutes and maintain and control their design architecture, such processors will obviously have excellent security and reliability, ensuring the flexibility and extensiveness of their applications. Therefore, computers based on domestic Loongson processors and corresponding macro-kernel operating system platforms will be able to realize various computing functions necessary for some pr...
