Function
The MegaCore functions in the Video and Image Processing Suite use standard
interfaces for data input and output, control input, and access to external memory.
These standard interfaces ensure that video systems can be quickly and easily
assembled by connecting MegaCore functions together.
The functions use the following types of interfaces:

Avalon-MM interfaces. This abstracted view is similar to that provided in the SOPC
Builder tool, where interface wires are grouped together as single connections.

MegaCore functions can connect between the function’s Avalon-ST interfaces and
functions using clocked video standards such as BT.656.
Avalon-ST interface—a streaming interface that supports backpressure. The
Avalon-ST Video protocol transmits video and configuration data. This interface
type allows the simple creation of video processing data paths, where MegaCore
functions can be connected together to perform a series of video processing
functions.
Avalon-MM slave interface—provides a means to monitor and control the
properties of the MegaCore functions.
Avalon-MM master interface—when the MegaCore functions require access to a
slave interface, for example an external memory controller.
Controller MegaCore
shows an example of video processing data paths using the Avalon-ST and
also have external interfaces that support clocked video standards. These
