MEMORY ACCESS APPARATUS, GRAPHIC SYSTEM, MEMORY ACCESS METHOD AND GRAPHIC METHOD

摘要

PURPOSE: To improve the memory use rate by mapping a part, which is not written with a first address format, in a memory by memory mapper so that it can be accessed with a second address format. CONSTITUTION: A graphics processor (GPU) 42 reads/writes information with first and second address formats. A memory mapper (PAL) 44 remaps memory pieces which don't include information recorded with the first address format so that the GPU 42 can access them with the second address format. That is, a part of a memory 46 can be linearly accessed as the result of remapping.
