Lookup table (LUT)
Matrox Meteor-II /Multi-Channel has three 256x8-bit input
lookup tables (LUTs), allowing independent re-mapping of
three 8-bit input streams.
The LUTs support RGB 8:8:8, RGB 5:6:5, and RGB 5:5:5 output
pixel formats. LUTs are programmed using the MIL-Lite
command, MdigLut().
User bits
Matrox Meteor-II /Multi-Channel supports four auxiliary TTL
user bits through the video input connector: two input and two
output. These are available for controlling external events such
as a strobe light or PLC. User bits are programmed using the
MIL-Lite command MdigControl().
Matrox Video Interface ASIC (VIA)
Each Matrox Meteor-II frame grabber for PC/104-Plus has a
Matrox Video Interface ASIC (VIA). The VIA acts mainly as a
bridge to the PCI bus. It uses 4 Mbytes of on-board SGRAM to
store data until the PCI bus is ready to receive it.
Matrox VIA can manage up to two simultaneous data streams.
For example:
It can grab into SGRAM, and concurrently transfer data
between SGRAM and another PCI device.
It can perform PCI data transfers and concurrently permit
the Host processor to access SGRAM.
Matrox VIA is capable of color plane separation of image input
on two, three, or four 8-bit or 16-bit components (for example,
RGB packed to RGB planar). This mechanism can be used to
merge line segments from monochrome multi-tap cameras,
connected to a Matrox Meteor-II /Multi-Channel frame grabber.
