Abstract
An apparatus includes a unified system/graphics memory and a memory controller. The memory controller is operative to receive client data access requests associated with one or more clients and a central processing unit (CPU) data access request associated with a CPU, to a plurality of memory channels for accessing the unified system/graphics memory. The memory controller is operative to provide access to the plurality of memory channels, in parallel, by the CPU and at least one client of the one or more clients. The memory controller is operative to prioritize the CPU data access request to the unified memory over the client data access requests to the unified memory and control the plurality of memory channels to access, in parallel, data for the CPU and data for the at least one client based on a request of the client data access requests and the CPU data access request.
