Detailed Description

Framework (FCF) The Frame Configuration Framework offers a set of functional units to easily configure the frame layout. The central element of the framework is the FrameBuilder.

The FrameBuilder is configured by a list of PhaseDescriptors. For each phase a CompoundCollector handles the compounds that are to be sent during the phase. Building the frame is done in three steps:

• The FrameBuilder activates the CompoundCollectors depending on the activations, listed in
• The FrameBuilder calls startCollection() of each compound collector. Compounds are collected dependend on the type of the collector.
• If all collectors have finished thier collection the have a chance to fine tune ther collection though their method: finishCollection(). Here dependencies to other compound collectors may be resolved.
• The frame builder triggers the first compound collector to start transmitting the compounds of the first phase. When the phase is finished the timing control starts the next timing node.

The CompoundCollector catches compounds from upper functional units. When the TimingControl starts the frame. All CompoundCollectors are finished by finishCollection(). The CompoundCollectors may do final configurations to their collected compounds. The TimingControl activates the TimingNode of the first Phase, which starts the compound transmission of the corresponding CompoundCollector. The TimingNode itself informs the TimingControl when its transmission has finished.

For an overview of the participating elements of the frame setup have a look at the following concept graph.
