    This paper illustrates how the real-time specification for Java (RTSJ) can be modified to allow applications to implement more flexible scheduling. The proposed approach is a two-level scheduling mechanism where the first level is the RTSJ priority scheduler and the second level is under application control. Minimum, backward-compatible changes to the RTSJ specification are discussed to motivate t... View full abstract»

    Convenience, reliability, and effectiveness of automatic memory management have long been established in modern systems and programming languages such as Java. The timeliness requirements of real-time systems, however, impose specific demands on the operational parameters of the garbage collector. The memory requirements of real-time tasks must be accommodated with a predictable impact on the time... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (258 KB) | HTML iconHTML

    This paper proposes a hybrid scheduling scheme for hard, soft and non-real-time tasks. The scheme creates a constant utilization server for each real-time scheduling policy and a total bandwidth server for all the non-real-time tasks with time sharing scheduling policy. Each server has a scheduler, called server scheduler, which is responsible for executing the ready-to-run tasks with the same sch... View full abstract»

    Many scheduling algorithms have been studied to guarantee the time constraints of real-time processes. Scheduling decision of these algorithms is usually based on parameters which are assumed to be crisp. However, in many circumstances the values of these parameters are vague. The vagueness of parameters suggests that we make use of fuzzy logic to decide in what order the requests should be execut... View full abstract»

    Service overlays that support distributed stream processing applications are increasingly being deployed in wide-area environments. The inherent heterogeneous, dynamic and large-scale nature of these systems makes it difficult to meet the quality of service (QoS) requirements of the distributed stream processing applications. In this paper we address the load balancing problem for distributed stre... View full abstract»

    Reduced time-to-market in spite of increasing the system's functionality, reuse of software on different hardware platforms, and the demand for performing validation activities earlier in the development phase raise the need for revising the state-of-the-art development methodologies for distributed embedded systems. The model driven architecture is a design methodology addressing these emerging r... View full abstract»

    Open multithreaded transactions constitute building blocks that allow a developer to design and structure the execution of complex distributed systems featuring cooperative and competitive concurrency in a reliable way. In this paper we describe an optimization to the standard open multithreaded transaction model that does not impose any participant synchronization when committing a transaction, b...

    While flash memory has been widely adopted for various embedded systems, space efficiency with reasonable performance has become a critical issue for the design of the flash-memory translation layer. The target of this paper is to improve the performance of existing designs by proposing a search-tree-like caching mechanism for efficient address translation. A replacement strategy with a low time c... View full abstract»

    Automated code synthesis is a constructive process that can be used to generate programs from specifications. It can, thus, greatly reduce the software development cost and time. The use of formal code synthesis approach for software generation further increases the dependability of the system. Though code synthesis has many potential benefits, the synthesis techniques are still limited. Meanwhile... View full abstract»
