Mixed-signal VLSI for neural and fuzzy sequential processors

A sequentiality study for mixed-signal VLSI implementations of neuro/fuzzy feedforward algorithms is presented. Implications of sequential processing and mixed-signal operation are derived. Basic building blocks for sequential mixed-signal neural and fuzzy computing are proposed, and two example sequential processors are described. Feedback from designed processors and subcircuits allows consideration of the technology constraints for analysis and extension to different sequentiality degrees.
