Abstract: Systems, apparatuses, and methods for implementing a memory fetch granule for real-time agents are described. A computing system includes a plurality of real-time agents coupled to memory via an interconnect fabric and a memory controller. The efficiency of the memory controller is determined by the number of bank groups in the memory devices coupled to the memory controller. A memory fetch granule is defined for the memory controller based on the amount of data that can be accessed in parallel on the memory device in back-to-back access cycles. Each real-time agent accumulates memory requests for sequential physical addresses until the amount of data referenced by the requests reaches the size of the memory fetch granule. Once the memory fetch granule is reached, the real-time agent sends the requests to the memory controller via the fabric. This helps to ensure that the requests will arrive at the memory controller near enough to each other to get grouped together.
