METHOD FOR REDUCING POWER CONSUMPTION OF EXTERNALLY CONNECTED DDR OF DATA CHIP AND DATA CHIP SYSTEM

摘要

The present invention relates to a method for reducing the power consumption of an externally connected DDR of a data chip and a data chip system. The method comprises: when the data chip system is lightly loaded or uncongested, storing the data to be written in a cache module added to the data chip; when the data chip system is heavily loaded or congested, starting the externally connected DDR, and after all the data in the externally connected DDR of the data chip system has been read out, shutting down the externally connected DDR. The data chip is capable of shutting down the externally connected DDR as much as possible during normal operation, thereby reducing the power consumption of the externally connected DDR of the data chip.
