A device and a method for processing CDMA compliant signals. The method includes receiving input signals; selecting, for each time interval out of multiple evenly length successive time intervals, multiple selected channel processing tasks that are scheduled to be at least partially executed during the time interval; storing input data at a first input buffer and providing data associated with at least one selected processing task from a second input buffer during even time intervals; and storing input data at the second input buffer and providing data associated with at least one selected processing task from the first input buffer during odd time intervals.
