A method ( 800, 900, 1800 ) and apparatus ( 100, 1710, 1950 ) for controlling data transfer in a processing system ( 200 ) accomplishes obtaining a set of input stream descriptors ( 505, 605 ), receiving physical parameters, and automatically generating a set of output stream descriptors ( 705 ). The set of input stream descriptors are used for transferring a set of target data embedded in a data stream ( 500, 600 ) to a device such as a memory, wherein locations of data in the set of target data embedded in the data stream are described by the input stream descriptors. The physical parameters that are received are related to transferring target data to the device. The set of output stream descriptors that are automatically generated can be used for transferring the set of target data to a device in a second data stream, wherein the set of output stream descriptors are determined by using at least one of the input stream descriptors or the physical parameters for improving at least one performance metric.
