Metadata Insertor

ENTITY METADATA_INSERTOR IS

Takes items from input MVB stream and inserts them to MFB stream as metadata without affecting the MFB flow in any other way.

Generics

Generic	Type	Default	Description
=====	MVB characteristics	=====	=====
MVB_ITEMS	integer	2
MVB_ITEM_WIDTH	integer	128
=====	MFB characteristics	=====	=====
MFB_REGIONS	integer	2
MFB_REGION_SIZE	integer	1
MFB_BLOCK_SIZE	integer	8
MFB_ITEM_WIDTH	integer	32
MFB_META_WIDTH	integer	0	Width of default MFB metadata
=====	Others	=====	=====
INSERT_MODE	integer	0	Metadata insertion mode options: 0 - Insert in SOF Region 1 - Insert in EOF Region 2 - Insert for valid all regions of the frame. Leads to a slight increase of logic paths. When two frames are present in one region, Metadata will be inserted for the one with SOP.
MVB_FIFO_SIZE	natural	0	Input MVB FIFO size. Set to 0 for no FIFO at all
MVB_FIFOX_MULTI	boolean	False	Enable FIFOX Multi for better effectivity MVB_FIFO_SIZE must be >= 16
DEVICE	string	“ULTRASCALE”	Target device: “ULTRASCALE”, “7SERIES”
