An asynchronous communication network in an integrated circuit is described. The asynchronous communication network comprises a plurality of circuit elements enabling the transmission of tokens, each circuit element having a component interface comprising: a routing network coupled to a first adjacent circuit element of the plurality of circuit elements; and a control circuit coupled to the routing network, the control circuit having a first input coupled to receive a first command requesting a detection of a token received at a second input of the control circuit, and a first acknowledgement output coupling a first acknowledgement signal indicating whether the first command is received at the first input. Methods of enabling asynchronous communication in an integrated circuit are also disclosed.
