Abstract
The invention provides a memory access method for overlapping partial boundary data in order to reduce or eliminate cross-page penalties when reading data. The method includes the step of a determining step to determine the maximum size of prediction blocks; a storing step to overlap partial boundary data from one side page of a page boundary into the other side page of the page boundary; and a reading step to read a prediction block from the page having all the data of the prediction block when the prediction block is at the page boundaries with overlapping data to eliminate cross-page penalties so as to increase the reading speed. Hence, the invention utilizes an overlapping method to eliminate cross-page penalties when reading the block data so as to increase the memory bandwidth as well as the reading speed.
