A fuzzy processor with an improved architecture. The fuzzy processor includes a fuzzy rule processor, an internal fuzzy instruction memory, an internal knowledge base memory, an arithmetic-logic unit, a control unit that can execute non-fuzzy instructions that are typical of conventional microprocessors, and an internal memory for storing the non-fuzzy instructions. The improved fuzzy processor architecture has an ability to load other knowledge bases and other fuzzy rules from outside the processor concurrently and transparently with respect to instruction processing. The processor can also process both fuzzy instructions and non-fuzzy instructions, can perform conditional and unconditional jumps within a set of fuzzy rules that are being processed, and can conditionally swap the knowledge base or the set of rules that are to be processed.

Fuzzy processor with architecture for non-fuzzy processing

A method and system for processing a plurality of fuzzy logic rules. The system includes a plurality of fuzzy logic lines, each fuzzy logic line corresponding to one of the fuzzy logic rules and including a calculating device. Each calculating device has an input terminal for receiving a series of weights and an output terminal for outputting an overall truth value according to the received series of weights and at least one logical operator of the fuzzy logic rule corresponding to the fuzzy logic line. The system further includes processing circuitry coupled to each fuzzy logic line, for receiving the overall truth value from each line, and outputting a fuzzy logic value according to the received overall truth values.
