Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0020] The multi-master bus conflict avoidance method provided by the embodiment of the present invention is applied to a multi-master bus system. Both primary and secondary systems can actively send letters. like figure 1 As shown, the multi-master bus system 1 includes a plurality of node devices 11 (such as figure 1 Node device 1, node device 2, ..., node device N) and at least one bus (such as figure 1 bus 12 in the figure 1 It is only indicated by a thick ...

Abstract

The embodiment of the invention provides a multiple-master-bus conflict avoiding method and a node device, and relates to the technical field of computers. The transmitting conflict problem of an existing multiple-master bus is solved. The multiple-master-bus conflict avoiding method includes the steps that the current running state of a bus connected with a first node device is determined through the first code device; if the current running state of the bus is the idle state through the first node device, when transmitting tasks are obtained, the first node device selects a target transmitting point to transmit in the first preset time section after the current time point, and the first preset time section comprises at least two transmitting points.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a conflict avoidance method of a multi-master bus and a node device. Background technique [0002] In order to improve the utilization efficiency of the multi-master bus, the existing multi-master bus system usually uses a multi-master mode to allocate the right to use the multi-master bus, that is, the node devices connected to the multi-master bus in the multi-master bus system all have the multi-master The right to use the bus, so that each node device can directly and proactively send a letter to the bus when it has a sending task. [0003] In the multi-master bus system, each node device connected to the multi-master bus can actively send a letter to the multi-master bus, so that each device has the opportunity to send and obtain data in real time; but because the devices connected to the multi-master bus When receiving a sending task, it will immediately send a letter to...
