Static dataflow with access patterns

Abstract: Signal processing and multimedia applications are commonly modeled using Static/Cyclo-Static Dataflow (SDF/CSDF) models. SDF/CSDF explicitly specifies how much data is produced and consumed per firing during computation. This results in strong compile-time analyzability of many useful execution properties such as deadlock absence, channel boundedness, and throughput. However, SDF/CSDF is limited in its ability to capture how data is accessed in time. Hence, using these models often leads to implementations tha… Show more

“…This leads to a defensive and potentially ineffective design where buffer sizes allocated for channels may be too big or too small [10]. To alleviate this problem, the Static Dataflow with Access Patterns (SDF-AP) model was proposed by [10] and formally presented in [13,14]. SDF-AP model is a big step towards improving the Synchronous Dataflow (SDF) model [12] by incorporating access patterns which describe the precise clock cycles at which data production/consumption occurs, as a result SDF-AP is considered to have moved SDF closer to the hardware.…”

“…The operational semantics of an SDF-AP model is defined by a labelled transition system N [13]. This transition system represents a model for SDF-AP model and its behaviour is easy to analyse and compare with the model for hardware.…”
