MITIGATING MAIN CROSSBAR LOAD USING DEDICATED CONNECTIONS FOR CERTAIN TRAFFIC TYPES

One embodiment of the invention sets forth a control crossbar unit that is designed to transmit control information from control information generators to destination components within the computer system. The control information may belong to various traffic paradigms, such as short-latency data traffic, narrow-width data traffic or broadcast data traffic. The physical connections within the control crossbar unit are categorized based on the different types of control information being transmitted through the control crossbar unit. The physical connections belong to the following categories: one-to-one (OTO) connections, one-to-many (OTM) connections, valid-to-one (VTO) connections, valid-to-many (VTM) connections wire-to-one (WTO) connections and wire-to-many (WTM) connections.
