Abstract: Techniques are described for interrupt handling. A device can obtain, at a first context buffer associated with a first interrupt handler, first processing configuration data associated with a first sensor; obtain, at a second context buffer associated with a second interrupt handler, second processing configuration data associated with a second sensor; obtain, at the first interrupt handler, an error indication associated with the first sensor; perform, by the first interrupt handler, based on the error indication, an error handling operation (where the error handling operation comprises flushing the first context buffer and/or invalidating the first processing configuration data in the first context buffer); obtain, at the second interrupt handler, during a time window interval between obtaining the error indication and a completion time of the error handling operation, from the second sensor, an interrupt request (IRQ); and output, based on the IRQ, the second processing configuration data to a processor.

Abstract: Aspects relate to an image signal processor that processes frames from different image sensors. An example device includes a memory and an image signal processor coupled to the memory. The image signal processor is configured to provide a first trigger to a first image sensor (the first image sensor being coupled to the image signal processor), receive a first frame from the first image sensor at a first time in response to the first trigger being received by the first image sensor, process the first frame, provide a second trigger to the second image sensor (the second image sensor being coupled to the image signal processor), receive a second frame from the second image sensor at a second time in response to the second trigger being received by the second image sensor (with the second time subsequent to the first time), and process the second frame.
