Multiprocessor system information acquisition method

Abstract

One embodiment of the invention discloses a multiprocessor system information acquisition method, which comprises the following steps that a multiprocessor information acquisition system is built, and the system comprises a node management module, an information acquisition module, a data storage module, a data interaction module and an information display module; power-on self-test is carried out on the system through the information acquisition module, and a working mode is published by the node management module according to a self-test result; the node management module controls the information acquisition module to perform information acquisition in the working process of the system in each system clock period; the collected information is stored in the data storage module and is sent to the node management module by the data interaction module; collected information is integrated through the node management module, and the integrated information is displayed by the information display module. Excessive system resources do not need to be occupied, and the method is decoupled from the work of the multiprocessor embedded system, so that the problem of information acquisition of the multiprocessor embedded system can be solved.

Description

technical field [0001] The present invention relates to the technical field of multiprocessor embedded systems, and more specifically, to a method for collecting information of a multiprocessor system. Background technique [0002] When the multi-processor embedded system is working, in order to ensure the normal operation of the system, it is necessary to collect the software operation information and hardware operation information of the system. Common collection methods include adding sensors and external information collection devices. The former method can only collect part of the system information, and its use is relatively limited. The latter requires an external device to take up space, which is inconvenient to use or space does not allow. None of the above-mentioned methods are fully suitable for the information collection of a multi-processor embedded system in a specific situation, such as a radar signal processing multi-processor embedded system.
