Communication appartus and method for priority control

摘要

The device has receiving messages storing units including receiving messages storing stacks (25A-25C) for storing messages of predefined priority level. Network tasks processing modules (26A-26C) and application tasks processing modules (27A-27C) interrupt a task that is in course of execution and execute a high priority task when a new receiving message has high priority information than the message that is in processing. An independent claim is also included for a communication method.
