Abstract
Evolutionary algorithms (EAs) are regularly used both
for the solution of scheduling problems, and for the cre-
ation of digital circuit designs. This paper describes a uni-
fied approach, which mixes the creation of a sequential cir-
cuit, with the scheduling and binding of operations.
This paper describes how Finite Impulse Response
Primitive Operator Filters (FIR POFs) can be created so
that they operate sequentially, over two cycles. These fil-
ters meet a frequency domain specification, and are also
optimised for area and delay. The circuits that were cre-
ated have a lower area than equivalent, purely combinat-
orial circuits.
The technique described here should be applicable to
