Address generating circuit of a two-dimensional coding table

摘要

An address generating circuit having a two-dimensional coding table which has respective coded words corresponding to a combination of x and y where the value of event A is determined as x and the value of event B as y (x and y are positive integers) between two events A and B, and stores the coded words in an address corresponding to each combination of x and y; coincidence detectors which input the values x and y of the events A and B and detect whether these values coincide with the integer of 1 to S (S is the maximum number among the integers satisfying S+log2S
