Objetivo AJACS will specify, develop and demonstrate an open technology allowing the use of Java in deeply embedded automotive electronic control units such as engine control systems. Existing work on small foot-print Java platforms and on real-time Java will be included in OSEK/VDX (Open Systems and the corresponding interfaces for automotive electronics/Vehicle Distributed eXecutive) technology. Native code approach will be investigated. Two automotive control units will be developed for validation. The resulting technology specification will be promoted in the OSEK/VDX and Java community for standardization.OBJECTIVESThe objective of AJACS is to specify, develop and demonstrate and open technology allowing the use of Java in deeply embedded automotive electronic control units (ECU) such as engine control systems. From an industrial viewpoint, the objective is to have an open technology which - relies on existing standards of the automotive industry, in particular OSEK/VDX - fully retains the benefits expected from object oriented language programming in terms of software structuring, reusability, dependability - full retains the WORA (Write Once Run Anywhere) attribute associated with Java - supports the same kind of real-time constraints which today Java based ECU are managing today - targets the type of electronic configurations that are in use in the industry: 16 tit microcontrollers and memory footprint ranging from 64 Kbyte to several hundred Kbytes ROM for the whole system.DESCRIPTION OF WORKAJACS will specify mechanisms and APIs which in particular - supports automotive control systems typical standards (e.g. coexistence with OSEK/VDX based applications written in C) - conforms to future Java deeply embedded standards and Java real-time standards - address automotive control systems typical timing constraints issues - address programming language issues such as memory management issues (garbage collection, persistent objects), synchronization issues (e.g. priority inversion), support of asynchronous external events (e.g. support of interrupt handlers in Java), support of asynchronous thread notification - address distributed communication or multiplexing needs (e.g. use of CAN, subsystem management). - allow for the right level of CPU performance (e.g. native code generation), allow the development in Java of device drivers The approach is to start from existing work in the area concerning small foot-print Java platforms, existing work concerning real-time Java, existing work concerning software infrastructure for automotive control systems in terms of RTOS (Real-Time Operating System) and control bus communication i.e. OSEK/VDX and to combine them into one single platform. Because of the need to support both real-time and small footprint, the benefit of native code approach will be investigated. The resulting platform will be validated by implementing two automotive control units. AJACS will disseminate and promote the results of the project as open technology through two channels: - the Java standardization channel- the OSEK standardization channel.
