Glossary-10
Electrical, Mechanical, and Thermal Specification
Intel PXA270 Processor
Glossary
Port:
Point of access to or from a system or circuit. For the USB, the point where a USB device is attached.
Power On Reset (POR):
Restoring a storage device, register, or memory to a predetermined state when power is
applied.
Process ID
: Process identifier
Programmable Data Rate:
Either a fixed data rate (single-frequency endpoints), a limited number of data rates
(32 kHz, 44.1 kHz, 48 kHz, …), or a continuously programmable data rate. The exact programming capabilities of
an endpoint must be reported in the appropriate class-specific endpoint descriptors.
Protocol:
A specific set of rules, procedures, or conventions relating to format and timing of data transmission
between two devices.
PSP:
Programmable Serial Protocol
PWM:
Pulse Width Modulator
QBS:
Qualification By Similarity. A technique allowed by JEDEC for part qualification when target parameters are
fully understood and data exist to warrant omitting a specific test.
QAM:
quadrature amplitude modulation. A coding scheme for digital data.
QPSK:
quadrature phase shift keying. A convention for encoding digital data into a signal using phase-modulated
communications.
RA:
See rate adaptation.
Radio Frequency Device:
These devices use radio frequencies to transmit data. One typical use is for bar code
scanning of products in a warehouse or distribution center, and sending that information to an ERP database.
Rate Adaptation:
The process by which an incoming data stream, sampled at Fs i, is converted to an outgoing data
stream, sampled at Fs o, with a certain loss of quality, determined by the rate adaptation algorithm. Error control
mechanisms are required for the process. Fs i and Fs o can be different and asynchronous. Fs i is the input data rate
of the RA; Fs o is the output data rate of the RA.
Request:
A request made to a USB device contained within the data portion of a SETUP packet.
Retire:
The action of completing service for a transfer and notifying the appropriate software client of the
completion.
RGBT:
Red, Green, Blue, Transparency
ROM:
Read Only Memory.
Root Hub:
A USB hub directly attached to the Host controller. This hub (tier 1) is attached to the host.
Root Port:
The downstream port on a Root Hub.
RTC:
Real-Time Clock
SA-1110:
StrongARM
*
based applications processor for handheld products
Intel StrongARM* SA-1111:
Companion chip for the Intel SA-1110 processor
SAD:
Sum of absolute differences
