1. A method comprising:

  • receiving a request for isochronous communication resources within a general input/output (GIO) fabric of an electronic appliance, wherein the isochronous communication resources include one or more virtual channels of the GIO fabric dedicated to isochronous communications with guaranteed bandwidth and service latency;

    determining whether one or more operating requirements associated with the received request can be accommodated by an appropriate subset of the GIO fabric to support an isochronous communication associated with the received request; and

    if the one or more operating requirements can be accommodated, generating an isochronous contract between a requester/completer pair of the isochronous communication and the GIO fabric, the isochronous contract to enforce one or more operating parameters under which the GIO fabric supports the isochronous communication.
