ROAFTS: a middleware architecture for real-time object-oriented adaptive fault tolerance support

Abstract: A middleware architecture named ROAFTS (Real-time Object-oriented Adaptive Fault Tolerance Support) is presented. ROAFTS is designed to support adaptive fault-tolerant execution of not only conventional process-structured distributed real-time (RT) application software but also new-style object-structured distributed RT application software. While ROAFTS contains fault tolerance schemes devised for quantitatively guaranteed RT fault tolerance, it is also designed to relax that characteristic while the application is in a soft RT phase in order to reduce resource use. Through three different prototype implementation experiences using both commercial operating system kernels and home-grown RT kernels, the middleware architecture has been refined and its basic capabilities and effectiveness have been validated. The fault tolerance schemes supported and the integrating architecture are discussed in this paper. Implementation experiences and some future tasks are also discussed.

Microprocessor support system

Abstract: The disclosed microprocessor support system provides a total "laboratory" environment for developing and testing application software as well as for debugging the microprocessor-based application machine itself. The microprocessor support system contains a time shared minicomputer equipped with a full set of peripherals which functions as the main or operating system. A data link connects this operating system with test equipment located at the site of the application machine. This test equipment consists of a field test unit which provides an interface between the application machine, a local keyboard terminal and the operating system such that an engineer at the site of the application machine has access through the field test unit to both the microprocessor-based application machine and the operating system with its sophisticated hardware and software resources to assist in developing and testing application software, as well as debugging the application machine itself.

ABE: an environment for engineering intelligent systems

Abstract: The ABE multilevel architecture for developing intelligent systems addresses the key problems of intelligent systems engineering: large-scale applications and the reuse and integration of software components. ABE defines a virtual machine for module-oriented programming and a cooperative operating system that provides access to the capabilities of that virtual machine. On top of the virtual machine, ABE provides a number of system design and development frameworks, which embody such programming metaphors as control flow, blackboards, and dataflow. These frameworks support the construction of capabilities, including knowledge processing tools, which span a range from primitive modules to skeletal systems. Finally, applications can be built on skeletal systems. In addition, ABE supports the importation of existing software, including both conventional and knowledge processing tools. >

Services to the Field: An Approach for Resource Constrained Sensor/Actor Networks

Abstract: More and more devices become network enabled and are integrated within one large, distributed system. The serviceoriented paradigm is the main concept to implement this approachand to cope with the heterogeneity of the underlying network. However, resource constraints imposed by the underlying hardware, such as 8-Bit micro controllers, require efficient protocols and often prohibit the use of technologies known from the Web service domain, the major implementation of the service-oriented paradigm. Nevertheless, a quick and seamless information flow between embedded devices and Web services is an important requirement for many application scenarios, e.g., real-time aware production management or the Internet of Things. Within this paper, we present an approach that allows to profit from the benefits of traditional SOA implementations, such as Web service interfaces and an IP compatible addressing scheme, and on the other hand can be implemented on resource constraint devices. The main idea is to use a data-centric processing paradigm at the device level and a gateway that mediates between the Web service and the embedded device world.

Managing a Reconfigurable Processor in a General Purpose Workstation Environment

Abstract: Reconfigurable processor hybrids are becoming an accepted solution in the embedded systems domain, but have yet to gain acceptance in the general purpose workstation domain. One problem with current solutions is their lack of support for the dynamic workloads and resource demands of a general purpose workstation. In this paper we describe and demonstrate a reconfigurable processor architecture that lets the operating system dynamically share the Field Programmable Logic (FPL) resource between a set of applications without the management overheads negating the benefit of having the extra resource.
