                                Abstract     



An approach to high-level synthesis for high-throughput DSP
applications will be discussed.  Such applications are typically found
in real-time video systems such as HDTV.  The method is capable of
dealing with hierarchical flow graphs containing loops with manifest
boundaries and linear index expressions.  The algorithm is based on
the model of periodic operations which allows optimizations across
loopboundaries.  Processing units and storage units are minimized
simultaneously.  The algorithm is implemented in the PHIDEO system.
The presentation will give an overview of the global system including
processing unit synthesis, scheduling, memory synthesis and address
generation.  Examples will be shown using a first prototype of the
system which is currently operational at the Philips Research Laboratories.
