Pixel Converter
This section describes the hardware structure and functionality of the pixel converter core.
Functional Description
The pixel converter core receives pixel data on its Avalon-ST input interface and transforms the pixel data
to the format required by the video sync generator. The least significant byte of the 32-bit wide pixel data
is removed and the remaining 24 bits are wired directly to the core's Avalon-ST output interface.
Parameters
You can configure the following parameter:
• Source symbols per beat—The number of symbols per beat on the Avalon-ST source interface.
