Self-timed Periodic Scheduling for a Cyclo-static DataFlow Model
Real-time and time-constrained applications programmed on many-core systems can suffer from unmet timing constraints even with correct-by-construction schedules. Such unexpected results are usually caused by unaccounted for delays due to resource sharing (e.g. the communication medium). In this paper we address the three main sources of unpredictable behaviors: First, we propose to use a determ...
متن کاملA Comparison of Synchronous and Cyclo-Static Dataflow
We compare synchronous dataflow (SDF) and cyclo-static dataflow (CSDF), which are each special cases of a model of computation we call dataflow process networks. In SDF, actors have static firing rules: they consume and produce a fixed number of data tokens in each firing. This model is well suited to multirate signal processing applications and lends itself to efficient, static scheduling, avo...

متن کاملStatic Scheduling for Cyclo Static Data Flow Graphs
There are few processes which display cyclically changing but predefined behavior. These processes can be represented using cyclo static data flow graphs (CSDFG). This capability results in a higher degree of parallelism. In this paper we present the iteration bound for a CSDFG which is used to find the integral static schedule and determine whether a csdf is live or not based on some calculati...
متن کاملMapping Parameterized Cyclo-static Dataflow Graphs onto Configurable Hardware
In recent years, parameterized dataflow has evolved as a useful framework for modeling synchronous and cyclo-static graphs in which arbitrary parameters can be changed dynamically. Parameterized dataflow has proven to have significant expressive power for managing dynamics of DSP applications in important ways. However, efficient hardware synthesis techniques for parameterized datafow represent...
