Abstract

PURPOSE:To secure the test-and-set order of the memory bit correspondence by combining the bit position decoder and the transfer logic sum gate. CONSTITUTION:When test-and-set T.S order of the EXC bit is executed within central process unit 1, the SPAB information is produced within arithmetic circuit ALU300 to be sent out to signal reception distributor SRD204. Then the identification No. of the SPAB information is compared with the contents of register 305 to secure the decision for its own SDR through the comparison coincidence. Thus decoder 309 is operated to send out the information to interface circuit INF205 to secure the identification for the T.S order. In case no coincidence is obtained through the comparison, SDR204 stops its operation.
