Claim Text:
1. An optical arbiter device between conflicting access requests to a shared resource sent by a plurality of N processing nodes of a network-on-chip system, for selecting a processing node from the plurality of N processing nodes seeking to access the shared resource, comprising: at least one primary optical arbiter bus; at least one optical source for transmitting a first optical signal in said at least one primary optical arbiter bus; and a sequence of N optical arbiter cells coupled with said at least one primary optical arbiter bus, each of these optical arbiter cells being associated with a processing node from the plurality of N processing nodes and each having means for selecting the processing node with which said each optical arbiter cell is associated by re-routing the first optical signal, wherein: said at least one optical source is designed to transmit a second optical signal propagated in an opposite direction to the first optical signal in relation to said sequence of N optical arbiter cells along said at least one primary optical arbiter bus; and the selection means of each optical arbiter cell are designed to select the processing node with which said each optical arbiter cell is associated by re-routing the first and second optical signals.
