Abstract

Interconnect circuitry (10) is configured to respond to a barrier transaction request to maintain an ordering of at least some transaction requests with respect to said barrier transaction request within a stream of transaction requests by not allow­ing reordering of at least some of said transactions request that occur before said barrier transaction request in said stream of trans­action requests with respect to at least some of said transaction requests that occur after said barrier transaction request in said stream of transaction requests; it also comprises a response signal generator, said response signal generator being responsive to re­ceipt of said barrier transaction request to issue a response signal, said response signal indicating to upstream blocking circuitry (90) that any transaction requests delayed in response to said barrier transaction request can be transmitted further.
