Glossary
• Acquisition path.
A path that has the components to, for example, digitize or capture a video input
signal.
•ASPM.
Active State Power Management. A hardware PCIe mechanism that autonomously
controls power consumption of the PCIe connectors in a computer. The actual
power consumed by a PCIe device depends on the PCIe traffic and on the
power-saving level to which the PCIe slot is configured. The power-saving level
of the PCIe slot is initialized by the operating system.
• Auxiliary I/O.
Auxiliary input/output. Auxiliary, multi-purpose signals that can be configured as
user-defined signals, or to some other functionality depending on the auxiliary
signal (for example, as trigger input or exposure output signals).
•Bandwidth.
A term describing the capacity to transfer data. Greater bandwidth is needed to
sustain a higher transfer rate. Greater bandwidth can be achieved, for example, by
using a wider bus or by increasing the clock frequency at which an interface or a
processing core operates (for example, increasing the DDR3 SDRAM clock
frequency).
• BNC connector.
Bayonet Neill-Concelman connector. A common connector used for 75 Ω coaxial
cables. Its fastener uses L-shaped slots to ensure that the coaxial cable is secured
to the Matrox Radient eV-CXP.
