Dynamic priority control based on latency tolerance

摘要

A dynamic priority controller monitors a level of data in a display engine buffer and compares the level of data in the display engine buffer to a plurality of thresholds including a first threshold and a second threshold. When the level of data in the display engine buffer is less than or equal to the first threshold, the dynamic priority controller increases a priority for processing display engine data in a communication channel. When the level of data in the display engine buffer is greater than or equal to the second threshold, the dynamic priority controller decreases the priority for processing the display engine data in the communication channel.

1. An apparatus comprising:
a data buffer; and dynamic priority controller coupled to the data buffer, the dynamic priority controller to:
monitor a level of data in the data buffer;compare the level of data in the data buffer to a plurality of thresholds, the plurality of thresholds comprising a first threshold and a second threshold;when the level of data in the data buffer satisfies a condition pertaining to the first threshold, increase a priority for processing data associated with the data buffer in a communication channel;when the level of data in the data buffer satisfies a condition pertaining to the second threshold, decrease the priority for processing data associated with the data buffer in the communication channel; andwhen the level of data in the data buffer does not satisfy the condition pertaining to the first threshold and does not satisfy the condition pertaining to the second threshold, maintain a current priority for processing data associated with the data buffer in the communication channel.
