Abstract

An example apparatus includes: a host controller offload capability detector to determine that a media stream offload capability is available in the peripheral interface host controller; a media stream offload arbiter to send a media stream offload request to a media processor manager based on the media stream offload capability and based on a peripheral device being connected to the peripheral interface host controller; and an endpoint mapper to generate an endpoint table entry corresponding to the peripheral device, the endpoint table entry to assign a first communication interface of the peripheral interface host controller to transfer a media stream corresponding to the peripheral device between the media processor and the peripheral interface host controller without the media stream being routed to an application processor that is in circuit with the peripheral interface host controller and in circuit with the media processor.
