摘要： A frame rate adjustment method to reduce frame rate jitters in a display process includes: a terminal obtains a computing-access ratio relationship, where the computing-access ratio relationship is used to reflect a ratio between computing tasks and access tasks executed by the terminal; obtains a first working frequency table corresponding to the computing-access ratio relationship, where the first working frequency table includes CPU performance parameters generated when a DDR SDRAM and a CPU work on different working frequency combinations; selects from the first working frequency table based on the CPU performance parameter, a target CPU-DDR SDRAM working frequency combination that meets preset target frame processing duration; and instructs the DDR SDRAM to work on a target DDR SDRAM working frequency in the target CPU-DDR SDRAM working frequency combination, and instructing the CPU to work on a target CPU working frequency in the target CPU-DDR SDRAM working frequency combination.
