STATIC TIMING ANALYSIS APPARATUS FOR DISTRIBUTED REAL-TIME EMBEDDED SOFTWARE AND METHOD THEREFOR

摘要

A static timing analysis apparatus and method for distributed real-time embedded software is provided. The static timing analysis apparatus includes: a task analyzer analyzing tasks per processor from a source code of real-time embedded software if the source code exists or a design model of a corresponding piece of the real-time embedded software if the source code does not exist; a message analyzer analyzing messages per network from the source code or the design model; a task worst-case response time analyzer analyzing a worst-case response time of each task, which is taken account of a scheduling policy of a corresponding operating system at which said each task is operated, based on the task analysis result for each processor and the message analysis result for each network; and a task real-time analyzer analyzing whether the analyzed worst-case response time of each task exceeds a deadline of the corresponding task.
