Intel® PXA270 Processor
Glossary
End User: The user of a host.
Endpoint: See device endpoint.
Endpoint Address: The combination of an endpoint number and an endpoint direction on a USB device. Each
endpoint address supports data transfer in one direction.
Endpoint Direction: The direction of data transfer on the USB. The direction can be either IN or OUT. IN refers to
transfers to the host; OUT refers to transfers from the host.
Endpoint Number: A four-bit value between 0H and FH, inclusive, associated with an endpoint on a USB device.
Envelope detector: An electronic circuit inside a USB device that monitors the USB data lines and detects certain
voltage related signal characteristics.
EOF: End-of-(micro)Frame.
EOP: End-of-Packet.
EOTD: Enhanced Observed Time Difference
ETM: Embedded Trace Macrocell, the ARM* real-time trace capability
External Port: See port.
Eye pattern: A representation of USB signaling that provides minimum and maximum voltage levels as well as
signal jitter.
FAR: Fault Address Register, part of the ARM* architecture.
False EOP: A spurious, usually noise-induced event that is interpreted by a packet receiver as an EOP.
FDD: The Mobile Station transmits on one frequency; the Base Station transmits on another frequency
FDM: Frequency Division Multiplexing. Each Mobile station transmits on a different frequency (within a cell).
FDMA: Frequency Division Multiple Access. An analog standard that lets multiple users access a group of radio
frequency bands and eliminates interference of message traffic.
FHSS: See Frequency Hopping Spread Spectrum.
FIQ: Fast Interrupt Request. See Interrupt Request.
Frame: A 1 millisecond time base established on full-/low-speed buses.
Frame Pattern: A sequence of frames that exhibit a repeating pattern in the number of samples transmitted per
frame. For a 44.1 kHz audio transfer, the frame pattern could be nine frames containing 44 samples followed by one
frame containing 45 samples.
Frequency Hopping Spread Spectrum: A method by which a carrier spreads out packets of information (voice or
data) over different frequencies. For example, a phone call is carried on several different frequencies so that when
one frequency is lost another picks up the call without breaking the connection.
Fs: See sample rate.
FSR: Fault Status Register, part of the ARM* architecture.
