US 12,526,376 B2 · Sensor interrupt handling

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.

Dependent claims

A method for interrupt handling comprising:

obtaining, at a first context buffer associated with a first interrupt handler, first image processing configuration data associated with a first image sensor;
obtaining, at a second context buffer associated with a second interrupt handler, second image processing configuration data associated with a second image sensor, different from the first image sensor;
obtaining, at the first interrupt handler, an error indication associated with the first image sensor;
performing, by the first interrupt handler, based on the error indication associated with the first image sensor, an error handling operation, wherein the error handling operation comprises at least one of flushing the first context buffer or invalidating the first image processing configuration data in the first context buffer;
obtaining, at the second interrupt handler, during a time window interval between obtaining the error indication associated with the first image sensor and a completion time of the error handling operation, from the second image sensor, an interrupt request (IRQ);
and
outputting, based on obtaining the IRQ, the second image processing configuration data to an image processor.
