ABSTRACT:
A graphics device implemented in accordance with one embodiment of the invention includes a first request path to a local memory interface for low-priority read transactions and a second request path to the local memory interface for low-priority write transactions. The second request path is also used for read transactions received over a system bus. The graphics device further includes an arbiter that arbitrates between the first request path and the second request path, with the second request path having a higher priority than the first request path.
