Embodiment Construction

[0021] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0022] Fig. 1 is the active detection system diagram of a kind of multi-core processor provided by the present invention, and system comprises:

[0023] The liveness detection task is used to construct the liveness detection message, and regularly sends the liveness detection message to each data plane core liveness detection agent task. If the core is abnormal, reset the abnormal data plane core by setting the corresponding hardware register;

[0024] The liveness detection agent task is used to construct the liveness detection response message, and reply the liveness detection task with the liveness detection response message after receiving the liveness detection message.

[0025] Fig. 2 is a diagram of an activity detection method of a multi-core processor provided by the present invention, the method comprising:

Abstract

The present invention aims to provide a liveness detection method for a multi-core processor, the multi-core processor includes a control plane core and a data plane core, the method includes: creating a liveness detection task when the control plane core is running, and constructing an active Detecting messages, creating a liveness detection proxy task when the data plane core is running, the liveness detection proxy task constructs a liveness detection response message; the liveness detection task regularly sends liveness detection messages to the liveness detection proxy tasks on each data plane core, After the liveness detection agent task receives the liveness detection message, it will reply the liveness detection response message to the liveness detection task; If there is an exception, reset the abnormal data plane core by setting the corresponding hardware register. The present invention also provides a liveness detection system of a multi-core processor, which includes a liveness detection task and a liveness detection agent task.

Description

technical field [0001] The present invention relates to the field of processors, and more specifically, to a method for detecting core activity when a multi-core processor is applied in the communication field. Background technique [0002] With the advent of the information age and the emergence of various new technologies and services, users have higher and higher bandwidth requirements for mobile communications and data communications. In order to meet the high bandwidth requirements of individual users, operators require mobile communications equipment and data Communication equipment has large capacity, high access and high processing performance. In order to meet the requirements of large capacity, high access and high processing performance, a large number of multi-core processors with high processing capabilities have been used in mobile communication devices and data communication devices. [0003] A multi-core processor is a processor that integrates multiple core...
