Abstract
A data processing apparatus which circulates a packet on a ring bus by connecting a plurality of communication modules to the ring bus and causing each communication module to send the packet to an adjacent communication module in synchronism with a predetermined periodical signal includes a plurality of data process modules each connected to a corresponding one of the plurality of communication modules to process data held in the packet, and an input/output module connected to at least one of the plurality of communication modules to receive/output data from/to the communication module. The number of circulations of data through the ring bus, which is input from the input/output module to one of the communication modules, until the data completes a predetermined processing and is received by the input/output module is acquired. The frequency of the periodical signal is changed in accordance with the number of circulations.
