Glossary
• Acquisition path.
A path that has the components to, for example, digitize or capture a video input
signal. Some video sources require multiple acquisition paths.
• 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
. Non-video digital signals that can support one or more
functionalities depending on the auxiliary signal (for example, trigger input or
timer output).
• 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).
