Abstract
In a longest coincidence data detecting apparatus, a control section distributes an external data to the N M-bit associative memory units to satisfy a relation of X.sub.ij =Y.sub.Nj+i where each of N and M is an integer more than 1, 0.ltoreq.i<N, 0.ltoreq.j<M, i and j are integers, X.sub.ij is a j-th bit of the i-th one of the N associative memory units, and Y.sub.k is a k-th bit of the external data. Each of the N associative memory units compares a distributed portion of the external data and a corresponding portion of an internal data in a designated bit region from a most significant bit of the distributed portion, and outputs a matching signal when the distributed portion of the external data portion and the corresponding portion of the internal data are coincident with each other in the designated bit region.
