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

Aspects relate to an image signal processor that processes frames at changing frame rates. An example method includes receiving, by an image signal processor, a first sequence of image frames from an image sensor at a first frame rate, processing each image frame of the first sequence of image frames at the first frame rate, and receiving from the image sensor an indication of a frame rate change from the first frame rate to a second frame rate. The method also includes configuring one or more filters of the image signal processor to process image frames from the image sensor in response to receiving the indication of the frame rate change from the image sensor, receiving a second sequence of image frames from the image sensor at the second frame rate, and processing each image frame of the second sequence of image frames at the second frame rate.

Image signal processor resource management

Techniques and systems are provided for processing image data. For example, an image signal processor can obtain (e.g., from a host processor) a first setting change indicator value indicating a change in parameter settings of the image signal processor. The image signal processor can obtain an image frame from an image sensor, and can determine a second setting change indicator value from the image frame. The second setting change indicator value can be provided to the image sensor from the host processor. The second setting change indicator value indicates a change in parameter settings of the image sensor. The image signal processor can compare the first setting change indicator value to the second setting change indicator value, and can determine whether to process the image frame or to drop the image frame based on comparing the first setting change indicator value to the second setting change indicator value.
