Implementation of time petri nets in real-time Java
Proceedings of the 4th international workshop on Java technologies for real-time and embedded systems - JTRES '06, 2006In this paper, we propose the use of the Java Real-Time extension as a target language in the automatic code generation from Time Petri Net models of Real-Time Systems. To support the classic centralized implementation techniques of Time Petri Nets, the temporal and concurrency Java primitives were analyzed. Performance analyses determined the overhead

On Real-Time Performance of Ahead-of-Time Compiled Java
Eighth IEEE International Symposium on Object-Oriented Real-Time Distributed Computing (ISORC'05), 2005One of the main challenges in getting acceptance for safe object-oriented languages in hard real-time systems is to combine automatic memory management with hard real-time constraints, while providing adequate general execution performance. An approach to real-time Java based on ahead-of-time compilation is presented, and real-time properties and ...

Blocking time monitoring in the real-time specification for Java
Proceedings of the 6th international workshop on Java technologies for real-time and embedded systems, 2008Blocking for resource accesses can have a crucial impact on a real-time system's ability to meet its deadlines. In priority-based systems, uncontrolled blocking can lead to potentially unbounded priority inversion. To counteract this, basic priority inheritance and priority ceiling protocols have been defined.

Enhancing OSGi with real‐time Java support
Software: Practice and Experience, 2012SUMMARYOSGi was designed with embedded systems in mind, its current support is insufficient for coping with one main characteristic of many embedded systems: real‐time performance. This article analyzes different key issues in providing OSGi with real‐time Java performance covering motivational issues, and different integration ways and challenges ...

Implementation and evaluation of real-time Java threads
Proceedings Real-Time Systems Symposium, 2002Java has many benefits such as security in distributed environments, reusability of code, and portability because it is architecture neutral. From those characteristics, Java is beginning to be used in many new environments. Even though Java provides various advantages, it still has problems which must be solved.

Embedded and real-time system design are properly separate concerns. Many embedded systems lack strict timeliness requirements, while many real-time systems (e.g., telephone central office switches) are not embedded. However, a number of embedded systems do have real-time requirements, including a number of products that fall under the I&M umbrella ...

Preemptible Atomic Regions for Real-Time Java
26th IEEE International Real-Time Systems Symposium (RTSS'05), 2006We present a new concurrency control abstraction for real-time systems called preemptible atomic regions (PARs). PARs a transactional mechanism that improves upon lock-based mutual exclusion in several ways. First, and foremost, PARs provide strong correctness guarantees.

jUAV: A Real-Time Java UAV Autopilot
2018 Second IEEE International Conference on Robotic Computing (IRC), 2018Recent developments in computing, sensing, and control have enabled the development of complex robot autonomy systems. Most such stacks involve time-critical tasks such as aerial vehicle control/collision avoidance and several noncritical tasks such as sensor processing and estimation.

The design and performance of real-time java middleware
IEEE Transactions on Parallel and Distributed Systems, 2003More than 90 percent of all microprocessors are now used for real-time and embedded applications. The behavior of these applications is often constrained by the physical world. It is therefore important to devise higher-level languages and middleware that meet conventional functional requirements, as well as dependably and productively enforce real ...
