Automated generation of an efficient MPEG-4 Reconfigurable Video Coding decoder implementation
This paper proposes an automatic design flow from userfriendly design to efficient implementation of video processing systems. This design flow starts with the use of coarsegrain dataflow representations based on the CAL language, which is a complete language for dataflow programming of embedded systems. Our approach integrates previously developed techniques for detecting synchronous dataflow (SDF) regions within larger CAL networks, and exploiting the static structure of such regions using analysis tools in The Dataflow interchange format Package (TDP). Using a new XML format that we have developed to exchange dataflow information between different dataflow tools, we explore systematic implementation of signal processing systems using CAL, SDF-like region detection, TDP-based static scheduling, and CAL-to-C (CAL2C) translation. Our approach, which is a novel integration of three complementary dataflow tools -the CAL parser, TDP, and CAL2C -- is demonstrated on an MPEG Reconfigurable...
