摘要： A system and method for efficiently scheduling memory access requests. A semiconductor chip includes a memory controller for controlling accesses to a shared memory and a display controller for processing frame data. In response to detecting an idle state for the system and the supported one or more displays, the display controller aggregates memory requests for a given display pipeline of one or more display pipelines prior to attempting to send any memory requests from the given display pipeline to the memory controller. Arbitration may be performed while the given display pipeline sends the aggregated memory requests. In response to not receiving memory access requests from the functional blocks or the display controller, the memory controller may transition to a low-power mode.
