• CoaXPress.
An asymmetric high-speed communication standard used primarily for video and
image data transfer. CoaXPress supports the transmission of video data, control
signals, triggers, and power all on the same coaxial line. CoaXPress supports
downlink data rates of up to 6.25 Gbits/sec (1.25, 2.5, 3.125, 5.0, and
6.25 Gbits/s) and an uplink data rate of 20.83 Mbits/sec.
• Contiguous memory.
A block of memory occupying a single, unbroken series of addresses.
• CXP.
See CoaXPress .
• DCF.
Digitizer configuration format . A format that defines how the video source and the
frame grabber are configured. The video source and the frame grabber are set to
the specified camera mode, which defines the format of transferred data. The DCF
can also configure the triggers, timers, and quadrature decoders.
DCF files have a . dcf extension.
• DDR3 SDRAM.
Double-data-rate type 3 synchronous dynamic random-access memory . A type of
general purpose consumer RAM. DDR3 SDRAM allows for data transfer at very
high speeds, which is important for I/O-bound functions. This type of memory
is inexpensive, high density, and very efficient as long as the data is accessed
contiguously.
• Digitizer configuration format.
