ABSTRACT:
In a unified memory computer system architecture, the unified memory is divided into at least two banks of memory. All but one of the memory banks is reserved for access exclusively by the host memory controller, and only one bank of memory is shared between the host memory controller and the video controller. Host accesses to the non-shared bank of the unified memory can take place concurrently with video controller accesses to the shared bank of memory.
