Intel PXA270 Processor
Glossary
Sample:
The smallest unit of data on which an endpoint operates; a property of an endpoint.
Sample Rate (Fs):
The number of samples per second, expressed in Hertz (Hz).
Sample Rate Conversion (SRC):
A dedicated implementation of the RA process for use on sampled analog data
streams. The error control mechanism is replaced by interpolating techniques. Service A procedure provided by a
System Programming Interface (SPI).
Satellite Phone:
Phones that connect callers by satellite. Users have a world-wide alternative to terrestrial
connections. Typical use is for isolated users, such as crews of deep-see oil rigs with phones configured to connect
to a satellite service.
SAV:
Start of active video
SAW:
Surface Acoustic Wave filter
SDRAM:
Synchronous Dynamic Random Access Memory.
Service Interval:
The period between consecutive requests to a USB endpoint to send or receive data.
Service Jitter:
The deviation of service delivery from its scheduled delivery time.
Service Rate:
The number of services to a given endpoint per unit time.
SIMD:
Single Instruction Multiple Data (a parallel processing architecture).
Smart Phone:
A combination of a mobile phone and a PDA, which allow users to communicate as well as perform
tasks; such as, accessing the Internet and storing contacts in a database. Smart phones have a PDA-like screen.
SMROM:
Synchronous Mask ROM
SMS:
Short Messaging Service. A service through which users can send text-based messages from one device to
another. The message can be up to 160 characters and appears on the screen of the receiving device. SMS works
with GSM networks.
SOC:
System On Chip
SOF:
See Start-of-Frame.
SOP:
Start-of-Packet.
SPI:
See System Programming Interface. Also, “Serial Peripheral Interface protocol.
SPI:
Serial Peripheral Interface
Split transaction:
A transaction type supported by host controllers and hubs. This transaction type allows full- and
low-speed devices to be attached to hubs operating at high-speed.
Spread Spectrum:
An encoding technique patented by actress Hedy Lamarr and composer George Antheil, which
broadcasts a signal over a range of frequencies.
SRAM:
Static Random Access Memory.
SRC:
See Sample Rate Conversion.
SSE:
Streaming SIMD Extensions
