Abstract: A method for software management of DMA transfer commands includes receiving a DMA transfer command instructing a data transfer by a first processor device. Based at least in part on a determination of runtime system resource availability, a device different from the first processor device is assigned to assist in transfer of at least a first portion of the data transfer. In some embodiments, the DMA transfer command instructs the first processor device to write a copy of data to a third processor device. Software analyzes network bus congestion at a shared communications bus and initiates DMA transfer via a multi-hop communications path to bypass the congested network bus.

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.

Abstract: A package device includes a processing device, memory dies and a memory controller. The memory controller die is coupled to the processing device and the memory dies. The memory controller die controls communication from the processing device to the memory dies and to an external memory device. The external memory device is external to the memory dies.

Abstract: Integrated circuits and integrated circuit dies include TSVs laid out in symmetrical patterns. Because of the symmetrical arrangement of the TSVs and associated routing patterns, an integrated circuit is able to support operation of multiple similar dies that are placed in different positions in the integrated circuit. This in turn simplifies the design and production of the multiple similar dies, thus reducing development and manufacturing costs for the corresponding integrated circuits.
