Zusammenfassung: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.
