TL;DR: It is argued that real-time COM should provide a policy specification interface between the application and the underlying (real-time) operating systems that is as declarative as possible, and it is concluded that COM can be extended to provide various real- time support services through this interface.

Abstract: While there has been substantial work on real-time CORBA-to offer real-time support in a distributed heterogeneous environment with standard real-time middle-ware, comparatively less work has been done to investigate support for real-time applications in COM, the direct competitor of CORBA. In this paper, we examine the COM technology and explore the possibility of providing real-time support in COM. We argue that real-time COM should provide a policy specification interface between the application and the underlying (real-time) operating systems that is as declarative as possible, and we conclude that COM can be extended to provide various real-time support services through this interface. We shall discuss an experimental prototype targeted for real applications along the line of our proposal.

Methods for Reliable Simulation-Based PLC Code Verification
TL;DR: Four major problems with the OPC interface are described, and two possible solutions to the problems are presented: a general IEC 61131-3-based software solution, and a new OPC standard solution.

Jun Wang,Jianbo Su,Yugeng Xi +2 more
TL;DR: A framework for constructing flexible, robust and efficient software applications for multisensor fusion system (MFS) is described, which consists of four levels from bottom to top: sensor driver level, logical sensor level, fusion unit level and task unit level.

Adopting a software component model in real-time systems development
Frank Lüders
- 03 Dec 2003
TL;DR: The analysis considers both real-time systems in general, and a real-life industrial control system where some aspects the COM model have been adopted, and concludes that adopting Microsoft's COM, DCOM, and .NET models makes it possible to meet real- time requirements, but that some overhead must be expected and that special precautions may have to be taken to prevent loss ofreal-time predictability.

Real-time database: semantics and resource scheduling
Tei-Wei Kuo
- 20 Nov 1995
TL;DR: A rigorous semantic basis for the correctness of concurrency control of real-time data accesses is provided, a framework and algorithms for load adjustment to accommodate dynamic real- time systems are discussed, and efficient data-access policies are described which exploit a similarity relation over data objects.
