Communication scheduling system and method among cores of isomerization multi-core processor

Abstract

The invention relates to an inter-core communication and scheduling system and an inter-core communication and scheduling method based on a heterogeneous multi-core processor, which relate to the computer field. The inter-core task communication and scheduling system applied to the heterogeneous multi-core processor is designed by adoption of the symmetrical communication and scheduling method according to the characteristics of the heterogeneous multi-core processor; various inter-core communication messages and events are defined in the unified way through an inter-core event manager, and relationships among the inter-core messages, the inter-core events and inter-core tasks are established; and inter-core message data from a communication interface and a shared memory is processed, the events are set, task scheduling is triggered, and other operations are performed by an inter-core communication scheduler. The inter-core communication and scheduling system and the inter-core communication and scheduling method solve the problems of the communication efficiency for inter-core communication of different types of messages and task scheduling of the heterogeneous multi-core processor in the aspects of communication and scheduling, and solve the problem of complexity caused by the master-slave scheduling method.

Description

technical field [0001] The invention relates to the field of computers, in particular to communication and scheduling control technologies among heterogeneous multi-core processor cores. Background technique [0002] Currently, multi-core processors mainly have two structures. One is a symmetric isomorphic multi-core processor, in which each core has the same processor structure, shared memory and peripherals, and is mainly used in the field of general-purpose computers. One is heterogeneous multi-core processors, which have processor cores with different structures, have their own memory spaces and peripherals, and each processor core has its own system clock frequency, which is implemented through processor communication interfaces and part of shared memory Communication, this processor is mainly used in the field of embedded devices. According to the structure of the processor, the scheduling control system on the multi-core processor is roughly divided into two categori...

Problems solved by technology

If the communication interface is used to transmit data larger than a single transmission, multiple transmission, read and write, and storage operations are required, and the communication rate and data volume are limited, so the efficiency is reduced, and the performance of the entire processor cannot be fully utilized.
