Problems solved by technology

The disadvantage of this method is that software is required to manage the allocation, use and recycling of signals in the signal pool, and the number of available signals is limited by the total number of signals in the signal pool. Since signals are allocated by software, when allocated to a group of task commands When the signal flag is not recycled, this group of commands cannot be used repeatedly
Moreover, the commands of a group of tasks generated by the software cannot be used repeatedly

Abstract

The invention provides a multi-equipment synchronous control method and a control system. The method includes: setting a synchronous control command in a combination of task commands that need to be executed by multiple devices to control the execution of commands that have a dependency on the execution order, wherein the synchronous control command includes the identifier of the target device to be executed and a dependency indication parameter , the dependency indicating parameter is used to determine the dependent command; assigning a unique identifier to each command in the task command combination and distributing it to the corresponding target device for execution. The method and system according to the invention can realize synchronous control among devices and reduce management and usage overhead.

Description

technical field [0001] The invention relates to the technical field of information processing, in particular to a multi-equipment synchronous control system and control method. Background technique [0002] In a digital hardware platform or a system-on-chip (SOC), there are generally multiple devices working in parallel, and these devices need to be synchronized with each other during operation so as to be able to cooperate to complete a computing requirement. Computing requirements are first converted into a series of computing task commands according to the functions of each device and distributed to different devices for execution. These tasks generally have interdependencies. There are different synchronization methods in the prior art to solve this dependency problem. . At present, the synchronization methods between multiple devices mainly include: [0003] 1) Establish an independent connection between each two devices to achieve signal interaction. For example, fo...
