Synchronous data flow
A preliminary SDF software system for automatically generating assembly language code for DSP microcomputers is described, and two new efficiency techniques are introduced, static buffering and an extension to SDF to efficiently implement conditionals.
Static Scheduling of Synchronous Data Flow Programs for Digital Signal Processing
This self-contained paper develops the theory necessary to statically schedule SDF programs on single or multiple processors, and a class of static (compile time) scheduling algorithms is proven valid, and specific algorithms are given for scheduling SDF systems onto single ormultiple processors.

Manipulation and Compositing of MC-DCT Compressed Video
This work proposes algorithms to manipulate compressed video in the compressed domain using the discrete cosine transform with or without motion compensation (MC), and derives a complete set of algorithms for all aforementioned manipulation functions in the transform domain.
Static Rate-Optimal Scheduling of Iterative Data-Flow Programs via Optimum Unfolding
It is shown that recursions or loops in the programs lead to an inherent lower bound on the achievable iteration period, referred to as the iteration bound, and that unfolding any program by an optimum unfolding factor transforms any arbitrary program to an equivalent perfect-rate program, which can then be scheduled rate optimally.
