Abstract :
Many multimedia and telecommunications applications are modeled as multi-rate, parallel data flow systems. We present techniques to model and schedule such applications using structured systems of recurrence equations. We show that the schedule can be obtained first by computing the period of each component of the system, then by applying structured scheduling to the entire system. This method is implemented in the MMAlpha software, and it is applied to model a WCDMA uplink receiver.
