Abstract

The invention discloses a multi-core microprocessor and a control method thereof. The multi-core microprocessor comprises a plurality of processing cores, each processing core comprises a signal generation module, a signal filter, an edge detection module and a signal execution module, the signal filter is electrically connected with the edge detection modules of the other processing cores, the signal filter is configured to filter an initial control signal through a preset logic operation, and the signal execution module is configured to execute the filtering operation; the control signal set comprises at least one effective control signal and at least one invalid control signal. According to the method and the device, the technical problem that interruption false triggering or false awakening of other cores is easily caused due to lack of a corresponding filtering mechanism for a control signal sent by a certain processing core during control among a plurality of processing cores in the prior art can be solved.

Description

technical field [0001] The application belongs to the technical field of microprocessors, and in particular, relates to a multi-core microprocessor and a control method thereof. Background technique [0002] With the continuous development and improvement of science and technology, the demand for microprocessor functions is also getting higher and higher. Ordinary single-core microprocessors have been unable to meet the application requirements in some places, and multi-core microprocessors have been born. . On the one hand, multi-core microprocessors are slowly being favored by customers due to their advantages in execution efficiency. On the other hand, some problems brought about by the birth of multi-core microprocessors have also attracted widespread attention, especially the problem of how to reduce power consumption on the premise of ensuring efficiency. For this reason, in the prior art, a multi-core microprocessor generally wakes up a certain processing core only ...
