Exercise

• Assigning priorities to tasks
• DescriptionConsider the application main of the
  multi-media consumer terminal (see, e.g. slide 17
  of the examples), and the following two
  situations.
• (a)   All tasks only block on their input or
  output, but never on any other hardware resource.
• (b)  As a refinement of (a), the video decoder
  may block on a VLD (variable length decoder). It
  typically blocks multiple times on the VLD during
  the processing of a single frame.
• Assume RMS of the tasks of main.
• Questions
• Propose an assignment of (relative) priorities to
  the tasks of main for situation (a), and motivate
  it.
• Similar for situation (b).
