Abstract: Upon receiving a request (203) in an initiator interface protocol identifying information to be returned in-order, an integrated circuit protocol bridge circuit device (200) allocates, to the ordered request, entries in a first ordered queue (e.g., 211) and a first static queue (e.g., 213) for the initiator interface protocol, generates a plurality of split target requests in a target interface protocol from the ordered request, and allocates the plurality of split target requests to entries in a second ordered queue (e.g., 217) and a second static queue (e.g., 218) for the target interface protocol, so that, upon receiving a plurality of out-of-order target responses, an allocated entry in the first ordered queue (211) for the first ordered initiator request is deleted only after a plurality of counter fields in the first static queue indicate that target responses have been received for all of the plurality of split target requests.
