Abstract
A device having a calculation part and memory part which can directly deal with a word of a fuzzy set data type, that is, which can deal with a combination of an element and a grade corresponding to the element, to thereby obtain high speed general calculating ability for fuzzy sets. The calculation part has a grade operating unit and an element operating unit, and the data is input and output in a word type such that it has an element field and a grade field which are processed by the corresponding operating unit. The memory part is an associative type memory in which a search can be executed using an element as a key, and which, at a data writing, compares new data and stored data and stores the result of the comparison. Alternatively, the memory part can realize fuzzy set calculation under the same procedure as data transfer by using a function to execute fuzzy logical calculations on the memory module in addition to data transfer, to thereby obtain very high speed calculating ability for fuzzy sets.
