In fast prototyping of fuzzy hardware systems, CABs undertake adaptive membership functions, inferences, implications, fuzzy logic connectives, and current memories. The optimal interconnections of CABs then realize fuzzy rules of any input/output scale and in the same time utilize hardware resources in the FPAA. To achieve adaptive signal processing via physical manipulations of FPAA, the parameters of CABs are adapted with serial analog scan-chains, which precisely scan-in and -out current signals according to the error correction schemes. Digital shift registers transport bit-streams from the host to configure all PSBs in the FPAA and therefore interconnections of CABs are adaptively formed. Consequently, fuzzy rules are adapted. In addition, we also propose a simplification method for calculation of fuzzy operations including fuzzy arithmetic, matching degree calculation, and defuzzification. By operating the LR parameters, the simplication method efectively reduces the complexity of the fuzzy operations and thus the method is very useful for hardware implementation. 陳朝烈 2005 學位論文 ; thesis 74 |
