Abstract: Aspects of the disclosure are directed to error recovery. In accordance with one aspect, an apparatus includes a plurality of sensors configured to generate a plurality of sensor data; a plurality of sensor interfaces, wherein each one of the plurality of sensor interfaces is coupled to each one of the plurality of sensors; and an aggregator, coupled to the plurality of sensor interfaces, the aggregator configured a) to multiplex the plurality of sensor data into a single aggregator output stream, b) to detect a transmission error in the plurality of sensor data, and c) to recover the transmission error using an aggregator hardware without software involvement.

Abstract: An image processing system includes an image sensor configured to generate a video frame, the video frame having a data portion and a test portion, an inline front end (IFE) having at least one processing module, a first memory, a functional software register, and a test software register, the IFE configured to receive the video frame, process the video frame and store the processed video frame to a second memory, a test pattern generator configured to generate test data that is provided to the IFE during the test portion of the video frame, a multiple input signature register (MISR) test function configured to compute a MISR signature from the test data, and a comparison function configured to compare a verified version of the test data to the computed MISR signature in the IFE to determine whether a system interrupt should be generated.

Abstract: Systems and techniques are provided for generating an HDR image. An example method can include obtaining a first image and a second image that has an exposure that is greater than an exposure of the first image; setting pixels of the first image that are below a minimum threshold to a minimum value and pixels of the second image that are above a maximum threshold to a maximum value; retrieving, from memory, a compressed version of the first image with the pixels set to the minimum value and a compressed version of the second image with the pixels set to the maximum value; generating a first decompressed image including the first image with the pixels set to the minimum value and a second decompressed image including the second image with the pixels set to the maximum value; and generating an HDR image based on the first and second decompressed images.
