Abstract
An access arbitration module includes a plurality of active component communication ports for communicating with a plurality of active components, and includes a passive component communication port for communicating with a passive component. The access arbitration module also includes switching logic defined to control transmission of access communication protocol signals between each of the plurality of active component communication ports and the passive component communication port, such that an authorized one of the plurality of active component communication ports is connected in communication with the passive component communication port at a given time, and such that non-authorized ones of the plurality of active component communication ports are prevented from communication with the passive component communication port at the given time.
