EARP-1 - an evolvable analog research platform

This paper describes a new evolvable analog hardware research platform currently under development. This platform, called EARP-1, differs significantly from previous efforts, in that it has a coarse-grained, signal-flow architecture oriented towards implementing state-variable filters and control systems. This platform has been implemented in SSI CMOS digital and analog integrated circuits on several printed circuit board cards, and is controlled by a Windows/spl trade/-based PC.
