A real-time Java chip-multiprocessor [PDF]
ACM Transactions on Embedded Computing Systems, 2010 Chip-multiprocessors are an emerging trend for embedded systems. In this article, we introduce a real-time Java multiprocessor called JopCMP. It is a symmetric shared-memory multiprocessor, and consists of up to eight Java Optimized Processor (JOP) cores, an arbitration control device, and a shared memory. All components are interconnected via a system

Overview of Real-Time Java Computing [PDF]
Journal of Computing Science and Engineering, 2013 This paper presents a complete survey of recent techniques that are applied in the field of real-time Java computing. It focuses on the issues that are especially important for hard real-time applications, which include time predictable garbage collection, worst-case execution time analysis of Java programs, real-time Java threads scheduling and ...

Model Checking Real Time Java Using Java PathFinder [PDF]
, 2005 The Real Time Specification for Java (RTSJ) is an augmentation of Java for real time applications of various degrees of hardness. The central features of RTSJ are real time threads; user defined schedulers; asynchronous events, handlers, and control transfers; a priority inheritance based default scheduler; non-heap memory areas such as immortal and ...

Fault tolerance with real-time Java [PDF]
Proceedings 20th IEEE International Parallel & Distributed Processing Symposium, 2006 After having drawn up a state of the art on the theoretical feasibility of a system of periodic tasks scheduled by a preemptive algorithm at fixed priorities, we show in this article that temporal faults can occur all the same within a theoretically feasible system, that these faults can lead to a failure of the system and that we can use the data ...

Toward Libraries for Real-Time Java [PDF]
2008 11th IEEE International Symposium on Object and Component-Oriented Real-Time Distributed Computing (ISORC), 2008 Reusable libraries are problematic for real-time software in Java. Using Java's standard class library, for example, demands meticulous coding and testing to avoid response time spikes and garbage collection. We propose two design requirements for reusable libraries in real-time systems: worst-case execution time (WCET) bounds and worst- case memory ...

Scoped Types for Real-Time Java [PDF]
25th IEEE International Real-Time Systems Symposium, 2005 A memory model based on scoped areas is one of the distinctive features of the Real-Time Specification for Java (RTSJ). Scoped types ensure timely reclamation of memory and predictable performance. The price to pay for these benefits is an unfamiliar programming model that, at the same time, is complex, requires checking all memory accesses, and ...

A distributed Real-Time Java system based on CSP [PDF]
, 1999 CSP is a fundamental concept for developing software for distributed real time systems. The CSP paradigm constitutes a natural addition to object orientation and offers higher order multithreading constructs.

A family of real‐time Java benchmarks [PDF]
Concurrency and Computation: Practice and Experience, 2010 AbstractJava is becoming a viable platform for real‐time computing. There are production and research real‐time Java VMs, as well as applications in both the military and civil sectors. Technological advances and increased adoption of real‐time Java contrast significantly with the lack of benchmarks.

Developing interest management techniques in distributed interactive simulation using Java [PDF]
, 1999 Bandwidth consumption in distributed real time simulation, or networked real time simulation, is a major problem as the number of participants and the sophistication of joint simulation exercises grow in size.

A Real-Time Java Component Model
2008 11th IEEE International Symposium on Object and Component-Oriented Real-Time Distributed Computing (ISORC), 2008 Real-Time Specification for Java (RTSJ) is becoming a popular choice in the world of real-time programming. However, the complexities introduced by RTSJ bring needs for an extensive framework comprising all the aspects of RTSJ development. As the first contribution of this paper we present a real-time component model directly fitting the needs of RTSJ.
