NI PCIe-8255R User Manual
Field-programmable gate array. An FPGA is a semi-conductor device
which contains a large quantity of gates (logic devices), which are not
interconnected, and whose function is determined by a wiring list, which is
downloaded to the FPGA. The wiring list determines how the gates are
interconnected, and this interconnection is performed dynamically by
turning semiconductor switches on or off to enable the different
connections.
Hardware description language. An example of an HDL is VHDL—a
language used to design digital circuitry.
The act of removing or swapping a device when power is applied to it.
Institute of Electrical and Electronics Engineers.
IEEE 1394 Trade Association Instrumentation and Industrial Control
Working Group, Digital Camera Sub Working Group.
A signal which has no electrical connection to the overall system power.
Driver software for National Instruments IEEE 1394 and Gigabit Ethernet
interface devices.
The fundamental picture element in a digital image. The smallest
resolvable rectangular area of an image, either on a screen or stored in
memory. Each pixel has its own brightness and color, usually represented
as red, green, and blue intensities.
Programmable Logic Controller. An industrial computer used for factory
automation, process control, and manufacturing systems.
