• 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. For each connection,
CoaXPress supports downlink data rates of up to 12.5 Gbits/sec (1.25, 2.5, 3.125,
5.0, 6.25, and 12.5 Gbits/s) and an uplink data rate from0.02 Gbits/s
(21.33 Mbits/sec) to 0.4 Gbits/s (42.67 Mbits/sec).
• Contiguous memory.
A block of memory occupying a single, unbroken series of addresses.
• CXP.
See CoaXPress.
• DCF.
Digitizer configuration format. A file format that defines the input data format and,
for example, how to accept or generate video timing signals, such as horizontal
sync, vertical sync, and pixel clock.
DCF files have a .dcf extension.
• DDR4 SDRAM.
Double-data-rate type 4 synchronous dynamic random-access memory. A type of
general purpose consumer RAM. DDR4 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.
See DCF.
