Optimizing read only memory surface accesses
In accordance with some embodiments, a separate pipe is used in graphics processor for handling accesses, namely reads, to read only (RO) surfaces within caches. Moreover, the caches may have defined read only section and defined read write (RW) sections. The read only section may be accessed through a dedicated read only pipe and the read write section may be accessed through a read write pipe for those surfaces that can also be written. Thus, the read only sections are handled in a read only fashion without the need to accommodate writes.
