The MDSDF domain was developed by Mike Chen and is still very experimental. This domain is an extension of the Synchronous Dataflow model to multidimensional streams and is based on the work of Edward Lee [Lee93b]. MDSDF provides the ability to express a greater variety of dataflow schedules in a graphically compact way. It also allows nested resettable loops and delays. Additionally, MDSDF has the potential for revealing data parallelism in algorithms. The current implementation of the MDSDF domain only allows two dimensional streams, although we hope that many of the ideas used in the development of the domain can be generalized to higher dimensions.
