Abstract :
The design of a 50×106 fuzzy inferences per second (FIPS) controller is presented. Based on a 1.2-μm CMOS technology, the controller supports 64 rules, four inputs, and two outputs. An appropriate number of copies can be cascaded for extensions beyond these specifications. The design uses no custom-designed blocks. Performance is obtained through a streamlined architecture, particularly in performing defuzzification. As a result, the amount of work involved in retargeting it to a different technology is expected to be minimal
