摘要： PROBLEM TO BE SOLVED: To avoid reduction in the throughput of an NoC system.SOLUTION: An input switching device 200 is disposed between a specific one of a plurality of NoC routers of the NoC system and a plurality of functional blocks (NoC routers or IP) connected to the specific router. The specific router has a plurality of first buffers (FIFOs 311-315) for temporarily storing flits from the input switching device 200. A plurality of second buffers (FIFOs 211-215) in the input switching device 200 correspond to the plurality of functional blocks, respectively, to temporarily store the flits from the functional blocks. A control section 220 selectively sets one of the plurality of first buffers as the destination of the flit stored in each second buffer on the basis of free spaces of the plurality of first buffers. A distributor 230 outputs the flit stored in each second buffer to the destination set for the flit by the control section 220.

摘要： PROBLEM TO BE SOLVED: To raise transfer efficiency of a NoC system by simple control.SOLUTION: A NoC router supports a frit group in which destination information indicates a plurality of destinations. In the NoC router, a destination group dividing unit 132 divides the plurality of destinations indicated by frit group destination information into one or more destination groups. Specifically, the plurality of destinations are divided in such a way that each destination which can share part of transfer paths for destination to be reached starting from the NoC router will be included in a destination group for which a direction in which output to the part of transfer paths is made the direction of group transfer. A transfer execution unit 134 removes destinations which are not included in the destination group from the destination information for each destination group obtained by the destination group dividing unit 132 before it transfers each frit in the frit group successively in the group transfer direction of each destination group.

摘要： PROBLEM TO BE SOLVED: To reduce the number of times of packet communication between routers without increasing the number of FIFOs in routing in NoC. SOLUTION: This route determination circuit determines a route between IP cores in the Noc, and includes: a route candidate calculation part which calculates a plurality of route candidates from a first IP core to a second IP core at a destination on the basis of destination information outputted from the first IP core which transmits a request; and a route selection part which selects a route candidate with the lowest degree of congestion among the plurality of route candidates as a route on the basis of degrees of congestion of routers on the respective route candidates of the plurality of route candidates.
