POFGEN: a design automation system for VLSI digital filters with invariant transfer function

The structure, methodology and potential of a new design automation tool, POFGEN, for the generation of fixed function VLSI digital filters is described. The system accepts input data in the form of a coefficient vector and uses this to form a pipelined, multiplier-free architecture by employing primitive operator graph synthesis methods. The output from POFGEN is available either in the form of a structure diagram or as hardware description language (HDL) file for direct application specific integrated circuit (ASIC) generation
