Chapter 5: Functional Descriptions
Frame Reader

Other Frame Reader parameters affect only resources and performance, or both. For
more information, refer to
Figure 5–25. Frame Reader Output Pattern and Memory Organization
The Avalon Slave control port allows the specification of up to two memory locations,
each containing a video frame. Switching between these memory locations is
performed with a single register. This allows the Frame Reader MegaCore function to
read a series of frames from different memory addresses without having to set
multiple registers within the period of a single frame. This feature is useful when
reading very small frames, and helps to simplify control timing. To aid the timing of
control instructions and to monitor the core, the Frame Reader MegaCore function
also has an interrupt that fires once per video data packet output, which is the “frame
completed” interrupt.
