Problems solved by technology

The IPC method realizes information communication based on TCP / IP or shared memory. However, in a multi-core system, this information communication method cannot reflect the advantages of a multi-core system.
With the increase of the number of cores in a multi-core system, the complexity of the mechanism with the core as the basic information communication unit increases greatly. At the same time, this IPC method cannot achieve load balancing for multi-core system processing. When a large amount of information is aggregated to the control plane board to be processed , which may cause the processing capacity of the single board on the control plane to be overloaded, and at the same time, it is impossible to realize efficient communication when there are multiple instances of tasks in a multi-core system

Embodiment Construction

[0032] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0033] see figure 2 , propose an embodiment of the method of information delivery of the present invention, which includes:

[0034] Step S101, receiving the information to be delivered and the name of the target task sent by the source task;

[0035] Step S102, according to the name of the target task, look up the kernel number corresponding to the name of the target task in the preset global relationship table;

[0036] Step S103, searching for the corresponding kernel in the multi-core system according to the kernel number, and sending the information to be delivered to the task corresponding to the target task name in the kernel.

[0037] The task corresponding to the name of the target task in the kernel is the target task.

[0038] Further, in the above-mentioned embodiment of the information delivery method...

Abstract

The invention discloses a method and device for information delivery. The device includes: a receiving module for receiving the information to be delivered and the name of the target task sent by the source task; Find the kernel number corresponding to the target task name; the sending module is used to find the corresponding kernel in the multi-core system according to the kernel number, and send the information to be delivered to the task corresponding to the target task name in the kernel. The method and device for information delivery provided by the present invention can realize the delivery of information in a multi-core system or between multi-core systems, and the reliability of information delivery is high.

Description

technical field [0001] The present invention relates to the field of multi-core technology, in particular to an information delivery method and device. Background technique [0002] In an existing multi-core system, each processor is composed of multiple cores, and each core includes one or more hardware threads. Due to the complexity of the business, the communication equipment consists of various business modules, control modules and switching boards, and each board uses one or more multi-core processors. [0003] Information communication methods in existing multi-core systems such as figure 1 As shown, the information communication method follows the traditional single-core processing system mode, and tasks between boards and within a board realize information communication through IPC. The IPC method implements information communication based on TCP / IP or shared memory. However, in a multi-core system, this information communication method cannot reflect the advantage...
