Workload scheduler for computing devices with camera

A non-transient computer-readable medium having a plurality of instructions encoded thereon that when executed by at least one processor cause a process to be carried out, the process being configured to:

• initiate image capture by a camera subsystem based on input from a user-application to perform a first media task and a second media task;
• receive a plurality of event signals from a clock source at a predefined rate;
• and
• in response to receiving a first event signal of the plurality of event signals, dispatch a captured image frame from the camera subsystem to one of the first media task and the second media task;
• and
• in response to receiving a second event signal of the plurality of event signals, dispatch a captured image frame from the camera subsystem to the other of the first media task or the second media task.

A computer-implemented method for applying a workload scheduling policy in a camera hardware abstraction layer (HAL), the method comprising:

• receiving a set of media tasks associated with image frames captured by a camera subsystem at an identified resolution and framerate;
• determining if available memory bandwidth to perform the set of media tasks is sufficient to avoid power consumption above a given target consumption threshold during performance of the set of media tasks;
• and
• in response to the available memory bandwidth being sufficient, applying a legacy workload scheduler policy;
• and
• in response to the available memory bandwidth being insufficient, applying an optimized workload scheduler policy such that image frames are dispatched by the camera HAL to each media task of the set of media tasks in an alternating manner.
