发明名称 Methods and systems for reusing memory addresses in a graphics system
摘要 Methods and systems for reusing memory addresses in a graphics system are disclosed, so that instances of address translation hardware can be reduced. One embodiment of the present invention sets forth a method, which includes mapping a footprint in screen space to a group of contiguous physical memory locations in a memory system, determining a first physical memory address for a first transaction associated with the footprint, wherein the first physical memory address is within the group of contiguous physical memory locations, determining a second transaction that is also associated with the footprint, determining a set of least significant bits associated with the second transaction, and combining a portion of the first physical memory address with the set of least significant bits associated with the second transaction to generate a second physical memory address for the second transaction, thereby avoiding a second full address translation.
