Abstract:
1. An apparatus, comprising: an initiator agent coupled to a first Intellectual Property (IP) core within a device; two or more target agents, each target agent coupled to its own IP core within the device; and an interconnect coupled to the initiator agent and the two or more target agents, the interconnect, which includes an end-to-end width conversion mechanism, the conversion mechanism to convert data widths between the initiator agent and a first target agent of the two or more target agents, wherein one or more branches of pathways in the interconnect exist between the initiator agent and the two or more target agents, the conversion mechanism to access data width information of the initiator agent and the one or more branches of pathways to the one or more target agents to concurrently pre-compute width conversion signals for each of the target agent branches while an address decoder generates an address decode for the first target agent, wherein the end-to-end width conversion mechanism to compute target-dependent width support and burst type support information across multiple groups of potential targets at the same time, and then selects a correct target-dependent information based upon the address decode result for the first target supplied by the address decoder.
