Abstract:
1. A method comprising: using a memory control unit to divide a buffer comprising a two dimensional array of memory cells into at least first and second blocks, the at least first and second blocks being sized to substantially prevent image tearing where the size of each of the at least first and second blocks is dependent on a copying process and a writing process of sequential ones of the blocks; writing data to a first one of the blocks; copying said data from the first one of the blocks to a corresponding block of a display; displaying an image corresponding to the data from the first one of the blocks; wherein the writing and copying steps are repeated for sequential ones of the blocks such that the writing and copying of the data from the sequential blocks occurs partly simultaneously, and wherein the writing of data to the blocks is in a direction perpendicular to the direction of copying data from the blocks and each block after the first block has a maximum size substantially equal to a size of the immediately preceding block times a ratio of a speed of the copying process and a speed of the writing process of sequential ones of the blocks.
