PURPOSE:To enable cascade connection by controlling a cascade output terminal and a coincidence signal output terminal so as to be active/inactive according to which an input terminal for the cascade connection is active/inactive. CONSTITUTION:The system is constituted of the input terminal 19 and the output terminal 25 for the cascade connection and a controlling means 20. Data synchronizing with an external clock from the input terminal 12 is inputted from the input terminal 11, and is compared with a pattern string registered in a shift register 13 and an associative memory 14 in real time, and a comparison result signal 26 is outputted. As for an address in which coincidence occurs, the output from an encoder 15 enters the controlling means 20, and when the input terminal 19 is active, the output terminal 16 turns to be inactive independently of an all coincidence signal from the memory 14. A multiple coincidence signal output terminal 17 turns to be inactive only while the coincidence does not occur in the memory 14. |
