Abstract: Systems and methods for operating a DMA unit with address alignment are disclosed. These may include configuring a bandwidth control setting for a read job that includes a data transfer size corresponding to a first number of bytes. A second number of bytes to reach a read address alignment is determined. In a first data transfer, a third number of bytes substantially equal to the first number of bytes plus the second number of bytes are transferred. In subsequent data transfers of the read job, the first number of bytes are transferred to the data buffer. After the third number of bytes are transferred to the data buffer, a fourth number of bytes from the data buffer are transferred to a destination.

Abstract: A maximum timeout time for a communication between devices is determined. A time period is determined for a plurality of time zones based upon the maximum timeout time. A current time zone is updated every time period. A timeout zone for an outstanding transaction is associated with a first time zone to indicate when the outstanding transaction will timeout if not completed. In one embodiment, the time period for each time zone is approximately equal to the maximum timeout period divided by a predetermined number of time zones, which may be the total number of time zones, e.g. eight or sixteen.
