ABSTRACT:
An apparatus for implementing bus request routing to allow functionality with 2 way or 4 way processors, includes a bus configured to provide bus request routing; and a bus request route switching stage coupled to the bus and configured to select a first route configuration if two processors are coupled to the bus. The switching stage is also configured to select a second route configuration if more that two processors are coupled to the bus. The switching stage determines if two or more processors are coupled to the bus. A logic block may be used to determine the required configuration based on the detected processor population. A method of changing bus request routing to allow functionality with 2 way or 4 way processors, includes: detecting if a dual processor arrangement or a multi-processor arrangement is coupled to a bus; and selecting a first route configuration if a dual processor arrangement is coupled to the bus and selecting a second route configuration if a multi-processor arrangement is coupled to the bus.
