Method and device for executing a time-critical process in non-real-time operating system

Abstract

Method and device for executing time critical processing in a non-real-time operating system. The method includes capturing a message by a packet capturing tool; analyzing whether the message is a sample value message associated with the time critical processing, and when the message is a sample value message associated with the time critical processing, writing a data unit included in the sample value message into a first buffer; preprocessing the data unit, the preprocessing includes arranging and combining bytes of the data unit so that the bytes indicate sample value is located at specific position; writing the preprocessed data unit from the first buffer into a second buffer and triggering a real-time dedicated thread at the same time, in response to the preprocessed data unit in the first buffer reaching the predetermined number; and executing the time critical processing by reading the preprocessed data unit from the second buffer.
