The Scaler MegaCore function can process streams of pixel data of the types shown in
Table
The features and functionality of the Scaler II MegaCore function are largely the same
as those of the
using less area while delivering higher performance.
The Switch MegaCore function allows the connection of up to twelve input video
streams to twelve output video streams. For example, 1 to 2, 4 to 1, 6 to 6, and so on.
The connections can be reconfigured at run time via a control input.
shows an example 3 to 2 Switch with the possible connections for each input and
output.
The Switch MegaCore function does not support duplication or combining of streams.
(If these functions are required, use the Color Plane Sequencer MegaCore function.)
Each output from the Switch can be driven by only one input and each input to the
Switch can drive only one output. Any input can be disabled that is not routed to an
output, which stalls the input by pulling it's ready signal low.
Maximum frame width is specified in the parameter editor, the actual value is read from control
packets.
Maximum frame height is specified in the parameter editor, the actual value is read from control
packets.
