The invention discloses a system power consumption dynamic control method based on a many-core processor, and the method comprises the following steps: S1, setting Pu before a project is submitted, and setting Su to be 0; s2, operating the submitted subject, and automatically recording F0 of a many-core processor used by the subject; s3, judging whether the subject is ended or not, and if the subject is ended, skipping to S11; s4, acquiring Pr through a resource management system; s5, comparing Pr and Pu obtained in the step S4; s6, the Fr is lifted to the first gear, and the step S9 is executed; s7, if Su is 1, directly suspending the project to run, and skipping to S10, otherwise, setting Su to be 1, and skipping to S9; s8, reducing Fr by one gear, and jumping to S9; s9, after waiting for T, skipping to S3; s10, reducing the Fr by two gears, recovering task operation, and skipping to S3; and S11, recovering Fr to F0. According to the method, the problem that the system power consumption is not controlled du
