ABSTRACT:
Currently there is a lack of automated tools for digital filter design.  
The focus of this project is to create a tool which enables a designer 
to rapidly explore the digital filter design space.   This tool allows 
the designer to optimize various design parameters in order to meet 
specific hardware cost and clock frequency constraints.  Starting with a 
design specification consisting of filter coefficients and required 
sample period, this tool automatically synthesizes a dependence graph 
(DG), and allows the user to apply unfolding and cutset retiming 
transformations in order to explore design tradeoffs.  In order to 
create a more user friendly tool, we also plan to utilize existing graph 
drawing programs to allow visualization of possible filter designs.
