This disclosure provides systems, methods, and devices for wireless communication that support improved routing of image sensors that share a PHY within different secure domains. In a first aspect, a device may receive a packet from an image sensor along a physical data connection. The device may determine a virtual channel associated with the packet and may determining a secure domain for the packet based on the virtual channel. The first secure domain may be selected from a plurality of secure domains accessible via the physical data connection, such as based on a mapping maintained by the device. The device may then route the packet within the first secure domain such that further processing and storage of the packet occurs within the first secure domain, such as within a context base associated with the first secure domain. Other aspects and features are also claimed and described.

Image signal processor supporting multiple security domains on a shared physical link

A computing device includes a hardware resource, a component to send a transaction signal including a target address of the hardware resource, a security data associated with an initiator of the transaction signal, and a safety data associated with the initiator, and an access control unit coupled to the component and the hardware resource, the access control unit to receive the transaction signal, determine whether security access is granted based on the transaction signal, determine whether safety access is granted based on the transaction signal, and allow access to the hardware resource based on both the security access and the safety access being granted.

Computing device to provide access control to a hardware resource

Systems, methods, devices, and non-transitory media of the various embodiments facilitate real time playback of a digital broadcast by enabling reduction of the amount of time a receiver device's low power mode interface with a separate computing device operates in an operational/high power mode. The receiver device may associate a stream of media packets of a digital broadcast with system time clock timestamps indicating when the media packets were received, and store the media packets in a temporary packet buffer. Periodically, a media packet burst stored in the temporary packet buffer may be sent to the separate computing device via a low power mode interface operating in an operational/high-power mode different than a low power mode. The low power mode interface may be returned to the low-power mode until the next burst of packets is sent to the separate computing device.
