摘要
An apparatus for managing communication within a computing system which includes a processing unit and a plurality of peripheral units. The processing unit receives information from a plurality of loci within the computing system and determines an enablement profile in response to such information according to predetermined criteria. The processing unit responds to the enablement profile to selectively enable specified peripheral units. The apparatus comprises a monitoring circuit for monitoring the enablement profile; a logic circuit for logically treating the enablement profile and generating a feedback signal representative of the enablement profile; and a transmission circuit for communicating the feedback signal from the logic circuit to the processing unit. The processing unit responds to the feedback signal to determine whether to employ a transfer trapping discipline whereby transfers destined for a non-enabled peripheral unit are stored until the non-enabled unit is enabled. The invention further comprises a method for managing communications within such a computing system comprising the steps of monitoring the enablement profile; generating a feedback signal representative of the enablement profile; communicating the feedback signal to the processing unit; and configuring the processing unit to respond to the feedback signal to determine whether to employ a transfer trapping discipline.
