Method and system of display object pre-generation on windows of idle time available after each frame buffer fill tasks

One or more computer-readable non-transitory storage media embodying software that is operable when executed to:

• identify a start point and a yield point of a window of idle time that is available after each frame buffer fill task for a displayable region;
• determine that the window of idle time that is available after each frame buffer fill task is more than a predetermined minimum time period required for executing a pre-generation process comprising pre-generating one or more display elements for a requested content that is currently not visible and is outside of the displayable region;
• determine a first number indicating a number of display elements of the requested content that fit into the displayable region;
• determine an increment based on an application-specific rule;
• determine a second number indicating a number of display elements to pre-generate based on the first number and the increment;
• select one or more pre-generation tasks for pre-generating content for the second number of display elements of the requested content;
• in response to the determination that the window of idle time that is available after each frame buffer fill task is more than the predetermined minimum time period required for pre-generating the one or more display elements of the requested content, start, at the start point of the window of idle time, the pregeneration process for executing the one or more pre-generation tasks, wherein a pre-generation task for pre-generating content during the window of idle time is different from the frame buffer fill task;
• execute, during the pre-generation process, a subset of the one or more pre-generation tasks to pre-generate content for a corresponding subset of the display elements;
• stop, at the yield point, the pre-generation process before completing the one or more pre-generation tasks in response to the pre-generation process taking longer than the window of idle time, wherein one or more stopped pre-generation tasks are added to a queue to continue execution in the window of idle time after a next frame buffer fill task;
• and
• store the pre-generated subset of the display elements in an application-tailored recycler.

A system comprising:

• one or more processors;
• and
• one or more computer-readable non-transitory storage media coupled to one or more of the processors and comprising instructions operable when executed by one or more of the processors to cause the system to:
• identify a start point and a yield point of a window of idle time that is available after each frame buffer fill task for a displayable region;
• determine that the window of idle time that is available after each frame buffer fill task is more than a predetermined minimum time period required for executing a pre-generation process comprising pre-generating one or more display elements for a requested content that is currently not visible and is outside of the displayable region;
• determine a first number indicating a number of display elements of the requested content that fit into the displayable region;
• determine an increment based on an application-specific rule;
• determine a second number indicating a number of display elements to pre-generate based on the first number and the increment;
• select one or more pre-generation tasks for pre-generating content for the second number of display elements of the requested content;
• in response to the determination that the window of idle time that is available after each frame buffer fill task is more than the predetermined minimum time period required for pre-generating the one or more display elements of the requested content, start, at the start point of the window of idle time, the pregeneration process for executing the one or more pre-generation tasks, wherein a pre-generation task for pre-generating content during the window of idle time is different from the frame buffer fill task;
• execute, during the pre-generation process, a subset of the one or more pre-generation tasks to pre-generate content for a corresponding subset of the display elements;
• stop, at the yield point, the pre-generation process before completing the one or more pre-generation tasks in response to the pre-generation process taking longer than the window of idle time, wherein one or more stopped pre-generation tasks are added to a queue to continue execution in the window of idle time after a next frame buffer fill task;
• and
• store the pre-generated subset of the display elements in an application-tailored recycler.
