Abstract
A data write control method includes detecting a quantity of dirty blocks in a first memory when a write control apparatus is in write-back mode; separately predicting execution progress of a program run by a processor within a danger time period in the two write modes when the quantity of dirty blocks reaches a first preset threshold; when it is predicted that the execution progress of the program run by the processor within the danger time period in write-through mode is faster than the execution progress of the program run by the processor within the danger time period in write-back mode, switching a current data write mode to the write-through mode; and detecting the quantity of dirty blocks when the write control apparatus is in write-through mode and switching the current data write mode to the write-back mode when the quantity of dirty blocks decreases to a second preset threshold.
