Abstract

The newest versions of the most ubiquitous USB interface are 3.0/3.1. USB 3.0 improves utilization of bus throughput through the changing of system architecture and introduction a new scheduling algorithm. In some applications using USB ports (e.g. vision system), the quality of service (QoS) is required. This paper presents proposal of model of USB system based on theory of scheduling and definition of QoS for communication interfaces (in particular USB 3.0). Some experiments (using prepared USB 3.0 application) were performed to verify compliance with QoS and their results are shown in this article.

Notes

  1. 1.

    The symbols associated with \(i\)th transfer are tagged by transfer number in superscript.

  2. 2.

    This assumption simplifies further reasoning. In fact, the last transaction of a transfer may consist of less number of packets. Additionally, last transmitted packet may have smaller payload than previous packets.

  3. 3.

    In the particular case, it is permitted for isochronous write operation.
