The
not be exhibited by any Avalon-MM interface. Together with the list of supported
signals, these properties fully define an interface type.
The control interfaces of the Video and Image Processing Suite MegaCore functions
that do not use a waitrequest signal, exhibit the following transfer properties:
■
■
The Video and Image Processing Suite MegaCore functions use a common type of
Avalon-MM master interface for access to external memory. These master interfaces
should be connected to external memory resources via arbitration logic such as that
provided by the system interconnect fabric.

Table 4–11. Avalon-MM Master Interface Signal Types
The clock and reset signal types are optional. The Avalon-MM master interfaces can
operate on a different clock from the MegaCore function and its other interfaces by
selecting the relevant option in the parameter editor when and if it is available.
Some of the signals in
which only performs write transactions.
Some other signals are write-only and not required by a master interface which only
performs read transactions. To simplify the Avalon-MM master interfaces and
improve efficiency, read-only ports are not present in write-only masters, and write-
only ports are not present in read-only masters.
