چکیده

Dissertation to receive the academical degree " Doktoringenieur (Dr.-Ing.) " submitted to Acknowledgments I would like to thank my supervisor, Prof. Hermann Härtig, for his continuous support and all members of the Operating Systems Chair at the Dresden University of Technology for the pleasant working environment. I would like to thank my reviewers, Prof. Gernot Heiser and Prof. Gerhard Fettweis for their support and extremely quick response time. Special thanks for many helpful comments and discussions to Rich Uhlig and his team at the Intel Microprocessor Research Lab in Hillsboro (Oregon), where I spent two fantastic internships, especially Gil Neiger for proof reading and adding many helpful comments. Furthermore, I would like to thank Claude-Joachim Hamann for his persistent help in getting my formulas right, Marc Shand from Compaq SRC for his support and the opportunity to get access to the Pamette Board, and many others for helpful discussions and their valuable input. Last but not least, I would like to thank my parents for all their support and love during this time.

Controlling the Influence of PCI DMA Transfers on Worst Case Execution Times of Real–Time Software

The PCI Local Bus is used in all general purpose computer systems. Peripheral devices connected to this bus may perform transactions autonomously. If a processor accesses the main memory or performs an I/O instruction, the execution time of these operations depends on the working load of the PCI bus and of the communication protocols being used by the chip set. In this paper the influence of th...

Performance and Bus Transfer Influences

Introduction Real-time systems which offer guaranteed response times need to schedule all resources, including CPU cycles, caches and bandwidths of buses. In this review we present a methodology how to schedule real-time requests for SCSI bus based IO and show measurements about the influences between SCSI, ATM and CPU traffic on the PCI bus and the local memory bus. We propose a slowdown facto...

Impact of PCI-Bus Load on Applications in a PC Architecture

Any data exchanged between the processor and main memory uses the memory bus, sharing it with data exchanged between I/O devices and main memory. If the processor and a device try to transfer data at the same time, an impact can be seen on the processor as well as on the device. As a result, the execution time of an application on the processor may increase due to the memory-bus load generated ...

Designing and Testing a PCI-based Interconnect With Support for Real-Time Data Streams

Computer systems based on the popular Peripheral Component Interconnect (PCI) desktop bus are being used ever more frequently for the manipulation of real-time data. This paper presents the work done by the authors to adapt the PCI bus to meet the strict timing requirements for the transmission of real-time data through the provision of Quality of Service (QoS) guarantees.

A statistical analysis framework for bus reliability evaluation based on AVL data: A case study of Qazvin, Iran

Reliability is a fundamental factor in the operation of bus transportation systems for the reason that it signifies a straight indicator of the quality of service and operator’s costs. Todays, the application of GPS technology in bus systems provides big data availability, though it brings the difficulties of data preprocessing in a methodical approach. In this study, the principal component an...

MDSP: a modular DSP architecture for a real-time 3D laser range sensor

By combining a number of embedded digital signal processors (DSPs) within a desktop PC, we have developed a system that offers not only the mass storage, network utilities, user interface and presentation graphics of a regular PC, but also the real-time response rates normally associated only with embedded systems. In this paper we outline the design of such a system that has been built to demo...
