Defination:-Fuzzy Logic can be viewed as a super set of Boolean logic, as a
multi-valued logic. It adds degrees between the absolute truth and absolute false to cover partial truth in between. In simple terms, fuzzy logic involves classifying objects and functions into fuzzy sets which could be given linguistic phrases. It is a form of reasoning that is neither exact, nor absolutely inexact. First generation of fuzzy hardware was of analogue type and came from Japan in 1980’s. These processors used fuzzy gates in computation having switching times in nanoseconds with accuracy within 0.1%. However, they never found their way out of the research mainly due to lack of programmability. Second generation was Digital Fuzzy Processors. The name can be considered to be a misnomer as something can either be digital, two valued or fuzzy which is continuous. These digital processors however worked on fuzzy instruction sets utilizing multilayered structure in interfacing. An interface layer fetched the fuzzy inputs which were then written onto the fuzzy processor via the host MCU communicating with the fuzzy processor through a Dual Port Ram (DPRAM). This however had a disadvantage of increased latency, complexity of code and overhead for communication between the two processors. These successfully made into the market in 1990’s but were soon to be succeeded by the third generation of Integrated Fuzzy Processors. It can be achieved by two techniques, by integrating the two co-processors on the same chip thus increasing the speed and reducing communication overhead. This however leads to increase in chip size.Another approach is to enhance the existing instruction set. Read More About :- Introduction to Fuzzy Logic
