combine prior art references. In re Dembiczak, 175 F.3d 994,
1000-01, 50 USPQ2d 1614, 1617-19 (Fed. Cir. 1999).
On pages 11-13 of the brief, Appellants argue that
there is no suggestion in the prior art to combine the
teachings of Hitchcock with the teachings of Chi.
Specifically, Appellants point out that Hitchcock teaches a 5
method of automatically synthesizing data paths from a
behavioral description of a hardware design. The EMUCS
program implementing the method attempts to find a minimum
cost implementation of a hardware design given a dataflow
representation VT (Appellants' emphasis). The program
proceeds by binding abstract data flow elements onto hardware
elements in iterative fashion. Once all the hardware elements
have been bound, the program determines which implementation
would result in the optimum design given the parameter which
is to be optimized.
