To overcome the inefficiencies in processing fuzzy rules on sequential digital computers and the inflexibility of purely analog processors, we introduce a parallel architecture using analog processors with a digital interface. Our architecture for fuzzy processing supports ISA-based PC platforms. Single or multiple fuzzy units with analog processing cores can operate as stand-alone MISO or MIMO fuzzy logic controllers supporting a digital interface with a master PC (for setup, monitoring, and/or relational MIMO support).
