Method and apparatus for agent interfacing with pipeline backbone to locally handle transactions while obeying ordering rule

Abstract

In accordance with embodiments disclosed herein, there are provided methods, systems, and apparatuses for enabling an agent interfacing with a pipelined backbone to locally handle transactions while obeying an ordering rule including, for example, receiving a transaction which requests access to a backbone; decoding routing destination information from the transaction received, in which the decoded routing destination information designates the transaction to be processed either locally or processed via the backbone; storing the decoded routing destination information and the transaction into a First-In-First-Out (FIFO) buffer; retrieving the decoded routing destination information and the transaction from the FIFO buffer; and processing the transaction locally or via the backbone based on the decoded routing destination information retrieved from the FIFO buffer with the transaction.
