Abstract

PURPOSE: To secure the detection for the trace start point in a short time as well as realize the detection for the start point of the loop element which cannot be detected with the mask, by extracting one point every element while detecting the connection of patterns.
CONSTITUTION: The detector consists of binary pattern memory 1, address generation circuit 6, partial element connection related process part 7, element process part 8, connection related memory part 9, partial element start point coordinates memory 10 and run-length detection part 11 each. Circuit 6 consists of counters 610 and 620 and generates the address to give access to memory 1 and then set the memory value of the designated address to register 110. Process part 7 examines the partial element in terms of the connection relation to the partial element which is ahead by one row and in the order of the detection, and then gives the label for memorization based on the connection relation. Process part 8 extracts the partial element connection relation and the start point of the partial element. Memory 9 consists of connection related memory 5 which memorizes the connection relation among labels, selection circuit 510 plus reading and writing registers 520 and 530 each. And detection part 11 memorizes the position addresses which change from 0 to 1 and vice versa in the form of a set of the run-length data.
