Ring-structured adaptable logic circuit for the classification of binary vectors

A ring structure made of 8 bit random-access memory (r.a.m.) elements is described. The r.a.m.s. are used as variable-function logic devices. Several results are presented relating the stored functions to the overall system function. These include the detection of unique, isolated `1¿ bits (uniqueness) and unique strings of `1¿ bits (connectedness) in a binary vector.
