摘要： In a synchronization system adopted in a synchronous-multisystem control apparatus comprising a plurality of systems operating synchronously with each other at a fixed control period, the synchronous-multisystem control apparatus can be operated in a single-system mode in the event of failures occurring simultaneously in some of the systems.The synchronous-multisystem control apparatus employs a plurality of control circuits each provided for one of the systems. Any particular one of the control circuits comprises: a period-signal generating circuit for generating a period signal indicating a start point of a control period; a synchronization-reference selecting circuit for outputting a synchronization-reference signal by referring to period signals generated by the systems; and a control-period correcting circuit for correcting a control period of the particular system by forming a judgment on a synchronization shift of the period signal generated by the particular system from the synchronization-reference signal and keeping the control period as it is in case the synchronization-reference signal is not generated.

摘要： A microprocessor has N processing units, a detector for detecting a branch instruction (k-th instruction) which comes first in the instruction sequence of N instructions, function logic for effecting control such that the first to the k-th instructions are executed with the (N-k+1)-th through the N-th processing units. However, when parallel processing is possible, the function logic operates such that the first through the N-th instructions are executed in sequential order by the first through the N-th processing units. On the other hand, wherein a branch instruction (k-th instruction) is included in the N sequential instructions, the function logic operates such that the first through the k-th instructions are parallelly executed by the (N-p+1)-th through the N-th processing units.
