<p>A vector graphics data management unit (24) comprises a management table (25) that stores pointers and stores priority ranks for cacheing in a cache unit (23). The management table (25) also stores priority rank pointers existing at a lower level than the priority ranks cached by the cache unit (23). Upon receiving a drawing command, the vector graphics data management unit (24) evaluates whether a pointer included in the drawing command exists in the management table (25), and manages the management table (25) on the basis of a specific insertion rank used when a pointer does not exist.</p> |
