HIGH DEFINITION AUDIO ARCHITECTURE

摘要

In a preferred embodiment, there is provided apparatus locatable between a host interface on the upstream side of the apparatus and one or more non-High Definition Audio (HDA)-compatible Coder/Decoders (CODECs) on the downstream side of the apparatus. The apparatus comprises a High Definition Audio (HDA) controller connectable to the host interface on the upstream side of the apparatus, and a logic circuit on the downstream side of the HDA controller. The logic circuit is connectable to the one or more non-HDA-compatible CODECs on the downstream side of the apparatus and is compatible with the HDA controller on the upstream side of the logic circuit. The logic circuit is also arranged to be able to send responses to the HDA controller, during start up and during normal operation, which emulate the responses of HDA-compatible CODECs.
