The idea is to identify the concepts that simplify the ... requirement from the picture size and minimum frame rate requirements. The overall functionality requirement defines the pro- tocol between IP blocks in the system and their combined functionality. This ... is refined by a UML sequence diagram that shows the control and data transfers between IP blocks in the active mode of the system. In addition, the requirement is further refined by the functional...
