Abstract: In one form, an apparatus includes a memory controller. The memory controller includes a command queue and an arbiter. The command queue receives and stores memory access requests. The arbiter picks the memory access requests from the command queue based on a plurality of criteria, and provides picked memory access requests to a memory channel. The arbiter includes a streak counter for counting a number of consecutive memory access requests of a first type that the arbiter picks from the command queue. When the streak counter reaches a threshold, the arbiter suspends picking requests of the first type and picks at least one memory access request of a second type. The arbiter provides the at least one memory access request of the second type to the memory channel.

Abstract: In one form, a memory controller includes a command queue, an arbiter, and a replay queue. The command queue receives and stores memory access requests. The arbiter is coupled to the command queue for providing a sequence of memory commands to a memory channel. The replay queue stores the sequence of memory commands to the memory channel, and continues to store memory access commands that have not yet received responses from the memory channel. When a response indicates a completion of a corresponding memory command without any error, the replay queue removes the corresponding memory command without taking further action. When a response indicates a completion of the corresponding memory command with an error, the replay queue replays at least the corresponding memory command. In another form, a data processing system includes the memory controller, a memory accessing agent, and a memory system to which the memory controller is coupled.

Abstract: A system and method for efficiently relocating and initializing a block of memory of the computer system. For data initialization and data relocation, multiple registers in a processor are used for intermediate storage of data to be written into the memory. Regardless of whether the amount of data to initialize or relocate is aligned with the register data size, the processor writes the data into the destination buffer with write operations that only utilize the register data size. The write operations utilize the register data size when each of the start and the end of the destination buffer is aligned with the register width, when the start of the destination buffer is unaligned with the register width, when a source buffer and the destination buffer are unaligned with one another for a copy operation, and when the source buffer and the destination buffer overlap.
