Real-Time Characteristics Analysis and Improvement for OPRoS Component Scheduler on Windows NT Operating System

Abstract: The OPRoS (Open Platform for Robotic Service) framework provides uniform operating environment for service robots. As an OPRoS-based service robot has to support real-time as well as non-real-time applications, application of Windows NT kernel based operating system can be restrictive. On the other hand, various benefits such as rich library and device support and abundant developer pool can be enjoyed when service robots are built on Windows NT. The paper presents a user-mode component scheduler of OPRoS, which can provide near real-time scheduling service on Windows NT based on the restricted real-time features of Windows NT kernel. The component scheduler thread with the highest real-time priority in Windows NT system acquires CPU control. And then the component scheduler suspends and resumes each periodic component executors based on its priority and precedence dependency so that the component executors are scheduled in the preemptive manner. We show experiment analysis on the performance limitations of the proposed scheduling technique. The analysis and experimental results show that the proposed scheduler guarantees highly reliable timing down to the resolution of 10ms.

RTiK: Real-time implant kernel on microsoft windows

Abstract: In this paper, we propose a real-time implant kernel(RTiK) which will provides real-time capabilities on Microsoft Windows based on x86 platforms. The kernel-extension software provided in this research project will be developed by implanting expanded HAL(Hardware Abstraction Layer) to provide real-time capabilities in the kernel of Windows on x86 platforms. To Uniquely control timer interrupts, our product will facilitate the Local APIC(Advanced Programmable Interrupt Controller) of the x86 CPU. Experimental results show that RTiK guarantees a minimum response time of 0.1ms for each real-time task.
