Abstract

PURPOSE:To realize the processing with high availability for a ring-shaped network device by releasing a stop mode of the data transfer in response to the end of an output. CONSTITUTION:When an input inhibition state occurs at a processing module 1PM1 and a ring-shaped bus RB is filled with the data whose input is inhibited, a processing module 2PM2 request an output on the bus RB. Thus said output it kept waiting at an interface circuit IF and a conflict signal C is outputted. A control circuit CNT receives the signal C and stops the read-out of an FIFO memory QM. Thus this memory QM works as a queue formed on the bus RB and an idle state of data is transmitted on the bus RB to the processing module PM from the output part of the memory QM. When the data idle state reaches the module MP2, the output data is outputted to the idle data and the signal C is released.
