Embodiment Construction

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

[0022] figure 1 It is a diagram of an activity detection system of a multi-core processor provided by the present invention, and the system includes:

[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.

Abstract

The invention provides a detection method for testing the activity of a multi-core processor; wherein, the multi-core processor comprises a control level core and a plurality of data level cores. Themethod comprises the following steps: the control level core creates a activity detection task during operation, which forms a plurality of activity detection messages; each data level core creates aactivity detection proxy task, which forms a activity response message each; the activity detection task regularly transmits activity detection messages to the activity detection proxy tasks on each data level core, and the activity detection proxy tasks, after receiving the activity detection messages, return activity detection response messages to the activity detection task; if the control level core fails to receive the activity detection response messages replied by a data level core, the data level core will be deemed as abnormal, and the abnormal data level core can be reset by settinga corresponding hardware register. The invention also provides a activity detection system for the multi-core processor, which comprises a activity detection task and a plurality of activity detectionproxy tasks.

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...
