Embodiment Construction

[0029] The main technical idea of ​​the present invention is to enable the operating system running on the master core to have the leading management capability for all resources in the heterogeneous multi-core system by adopting a master-slave management structure. On the one hand, it is used for accessing resources in its own code On the other hand, it is also used to monitor the real-time behavior of other operating systems running on the slave core in the heterogeneous system, and when necessary, issue behavior adjustment commands to the other party, asking the other party to adjust its behavior, and the operation on the slave core The system receives and adjusts the behavior adjustment commands transmitted by the main operating system in real time, so that the main core operating system and the slave core operating system in the multi-core heterogeneous system can communicate and restrain each other, effectively solving the problem of the main core operating system and the ...

Abstract

The invention discloses a method used for harmonizing attemper among isomerization polycaryon and an isomerization polycaryon system, which realizes that an operation system running in the principal epipolar has the leading management ability to all resources in the isomerization polycaryon system by adopting the master-subsidiary management structure, and can monitor the whole operation of the isomerization polycaryon system, send behavior adjustment order to the opposite side at necessary moment to require the opposite adjust the behavior. The operation real time at the polycaryon receives the behavior adjustment order transmitted from a main operation system to have adjustment, thereby realizing mutual communication and restriction between a master operation system in the isomerization polycaryon system and a subsidiary operation system, which effectively resolves the problem of incapable of adjustment and attemper between the master operation system and the subsidiary system.

Description

technical field [0001] The invention relates to the field of computer operating systems, in particular to a method for coordinating scheduling among heterogeneous multi-cores and a heterogeneous multi-core system. Background technique [0002] With the improvement of chip design level and the improvement of application requirements, more and more multi-core (CPU) is applied to products. Most of the currently used heterogeneous multi-core systems use one of the cores as the main core to undertake the main resource management and complex logic operations; the remaining cores are used as slave cores to undertake tasks with simple logic but large amounts of data. [0003] In a heterogeneous multi-core system, the operating system running on each core executes concurrently. In the current operating system technology, each operating system can manage and schedule its own generated processes (or tasks) in a unified manner; operating systems with complex functions can also provide ...
