Embodiment Construction

[0047] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0048] This embodiment provides a static schedulability analysis method based on the AADL model in a multi-processor DIMA architecture system. DIMA is a distributed intelligent modular system. There are multiple processors in the system that can process multiple tasks in parallel. In a distributed system, each module in the system may need to send information to each other, and threads in partitions under different processors in the system may communicate with each other, so when calculating the schedulability of the entire...

Abstract

The invention discloses a schedulability analysis method based on a multiprocessor-based AADL model, which comprises the following steps: extracting the relevant information of each partition in the AADL system architecture and the binding relationship between each partition and a processor component; analyzing the relationship between each partition and the processing bind each thread component in each partition to a unique processor component; determine the execution timing of thread components in each partition, and calculate the response time of each thread component; Response time and deadline, calculate the schedulability of each thread component in the system; according to the schedulability of each thread component, the system schedulability is obtained. Through the above steps to analyze and calculate the schedulability of the multiprocessor-based AADL model, the schedulability analysis results of the system model are obtained, which provides a more accurate schedulability analysis method for the schedulability analysis method of the multiprocessor AADL model evaluation method.

Description

technical field [0001] The invention relates to a schedulability analysis method based on a multiprocessor-based AADL model. Background technique [0002] Structural Analysis and Design Language AADL (Architecture Analysis And Design Language) is a character drawing and graphical modeling language used to design and analyze performance-critical real-time systems. It is widely used in the aerospace industry for the construction of safety-critical application system models. Model, which can be used to describe the functional interface between components, and also describe the timing requirements of components. It can also describe the interactive relationship between components, such as data input and output, binding relationship between software components and hardware components, etc. Therefore, the designer may analyze and evaluate the model from various aspects. The following briefly describes the AADL model elements: [0003] Component is the main modeling unit of AADL...
