Abstract: Systems and methods for dynamic repartitioning of physical memory address mapping involve relocating data stored at one or more physical memory locations of one or more memory devices to another memory device or mass storage device, repartitioning one or more corresponding physical memory maps to include new mappings between physical memory addresses and physical memory locations of the one or more memory devices, then loading the relocated data back onto the one or more memory devices at physical memory locations determined by the new physical address mapping. Such dynamic repartitioning of the physical memory address mapping does not require a processing system to be rebooted and has various applications in connection with interleaving reconfiguration and error correcting code (ECC) reconfiguration of the processing system.

Abstract: A method for hardware management of DMA transfer commands includes accessing, by a first DMA engine, a DMA transfer command and determining a first portion of a data transfer requested by the DMA transfer command. Transfer of a first portion of the data transfer by the first DMA engine is initiated based at least in part on the DMA transfer command. Similarly, a second portion of the data transfer by a second DMA engine is initiated based at least in part on the DMA transfer command. After transferring the first portion and the second portion of the data transfer, an indication is generated that signals completion of the data transfer requested by the DMA transfer command.
