Abstract: A computer of a first node executes primary communication and secondary communication between a first node group and a second node group provided with nodes. On the basis of the transmission capabilities of a network, the computer computes the required time required to transmit data that has been designated as outgoing data since the start time of a periodically executed transmission process up until the current time, wherein the designated data is data from among the received data that has been successively designated as outgoing data. The computer determines whether or not the time equal to the current time plus the required time matches the start time of the primary communication periodically conducted between the nodes. On the basis of the determined results, the computer decides which data from among the received data to designate as outgoing data.

Abstract: Each of a plurality of master devices outputs a speed grade signal indicating a data transfer speed with a data transfer request. An arbiter arbitrates transfer requests and speed grade signals from the plurality of master devices. A clock enable generation circuit generates a clock enable signal with a varying ratio of a valid level according to the speed grade signal arbitrated by the arbiter. A slave device operates upon receiving a clock signal when the clock enable signal is at the valid level, and transfers data according to the transfer request arbitrated by the arbiter. Accordingly, the frequency of the clock signal which causes the slave device to operate may be changed for each transfer request, and a fine control of the power of the slave device may be easily performed. As a result, power consumption of the data processing system may be finely controlled.
