Development Automation of Real-Time Java

Abstract

Many applications in emerging scenarios, such as autonomous vehicles, intelligent robots, and industrial automation, are safety-critical with strict timing requirements. However, the development of real-time systems is error-prone and highly dependent on sophisticated domain expertise, making it a costly process. This paper utilises the principles of model-driven engineering (MDE) and proposes two methodologies to automate the development of real-time Java applications. The irst one automatically converts standard time-sharing Java applications to real-time Java applications, using a series of transformations. It is in line with the observed industrial trend, such as for the big data technology, of redeveloping existing software without the real-time notion to realise the real-time features. The second one allows users to automatically generate real-time Java application templates with a lightweight modelling language, which can be used to deine the real-time properties Ð essentially a synthesis process. This paper opens up a new research direction on development automation of real-time programming languages and inspires many research questions that can be jointly investigated by the embedded systems, programming languages as well as MDE communities. CCS Concepts: • Computer systems organization → Real-time systems; • Software and its engineering → Software notations and tools.

“…For both sides of the differential: Judgment formula (9) for the low value of the braking differential ratio, and judgment formula (10) for the high value of the braking differential ratio.…”

“…However, in the actual application process, the use of the mode and system needs to be further improved and can not give full play to the advantages of the application of PLC technology. How to integrate embedded PLC technology in electrical automation has become the focus of the modern electrical field and related units [8][9][10]. To this end, this paper focuses on analyzing the concept and characteristics of embedded PLC.…”
