Patent ID: 7652672

Claim:
A method for texture image management, performed by a 3D graphics engine, comprising: receiving information from an application, indicating that a texture image is stored in a first region of a memory device; determining whether the first region of the memory device is a read-only (RO) region or a read-write (RW) region by: acquiring a memory image stored in an executable file corresponding to the application; determining the first region of the memory device is the RO region when detecting an RO attribute of an input or output section comprising the first region from the memory image; and determining the first region of the memory device is the RW region when detecting an RW attribute of an input or output section comprising the first region from the memory image, wherein the read-only (RO) region resides inside a NOR flash memory and the read-write (RW) region resides inside a RAM (Random Access Memory); and generating an RO attribute corresponding to the indicated texture image to indicate that the texture image is stored in the RO region when determining that the first region of the memory device is the RO region, thereby enabling the texture image retrieved from the first region to be applied to a fragment.
