Abstract

PURPOSE: To secure the collection of the fault information without stopping the entire operation by memorzing the effective and ineffective states of the logic block action and making the ineffective and effective blocks carry out the shift action and the logic action respectively.

CONSTITUTION: The fault occurring, for example, in block 1a among logic blocks 1aW1n is informed to higher-rank control part 7 via fault signal 131a. Part 7 memorizes through register 71a the fact that control signal 122a is ineffective, and then sends fault information signal 701 including the information of block 1a to shift control part 5. Part 5 sends such coded signal 301 as to turn designation signal 302a to logic 1 and then stops transmission of distrubution clock 602a to stop the logic action of block 1a. After this part 5 turns shift mode signal 603 to logic 1 to make block 1a perform the shift action, and then transmits shift-out signal 101a to part 5. Meanwhile signals 302bW302n feature logic O, and blocks 1bW1n perform the original logic actions.
