Abstract
A vehicular device includes multiple CPU modules, multiple cache memories allocated to the CPU modules, respectively, and a memory synchronization unit configured to synchronize multiple surfaces drawn in the multiple cache memories. The memory synchronization unit divides the surfaces to be synchronized into multiple tiles, and sequentially synchronize the divided tiles from tiles for which drawing has been completed.
