Abstract
The present disclosure relates to a method for providing clock frequencies for computing cores, a chip and a data processing device. The method includes: causing a main clock frequency unit to provide a first main clock frequency for computing cores; testing the computing cores operating at the first main clock frequency to determine whether a pass rate of the computing cores is greater than an upper threshold or less than a lower threshold; when the pass rate is less than the lower threshold, causing an auxiliary clock frequency unit to provide a lower first auxiliary clock frequency for computing cores abnormally operating, causing the main clock frequency unit to providing the first main clock frequency for the remaining computing cores; when the pass rate is greater than the upper threshold, causing the main clock frequency unit to provide a higher second main clock frequency for the computing cores.
