Electrical, Mechanical, and Thermal Specification
Intel PXA270 Processor
Glossary
Full-duplex:
Computer data transmission occurring in both directions simultaneously.
Full-speed:
USB operation at 12 Mb/s. See also
low-speed and high-speed
.
Function:
A USB device that provides a capability to the host, such as an ISDN connection, a digital microphone,
or speakers.
GMSK:
Gaussian Minimum Shift Keying. A modulation scheme used in GSM.
GPRS:
General Packet Radio Service A technology that sends packets of data across a wireless network at speeds
up to 114 Kbps. Unlike circuit-switched networks, wireless users do not have to dial in to networks to download
information; GPRS wireless devices are “always on” in that they can send and receive data without dial-ins. GPRS
works with GSM.
GPS:
Global Positioning Systems
GSM:
Global System for Mobile Communications. A standard for how data is coded and transferred through the
wireless spectrum. The European wireless standard, also used in parts of Asia, GSM is an alternative to CDMA.
GSM digitizes and compresses data and sends it across a channel with two other streams of user data. GSM is based
on TDMA technology.
Hamming Distance:
The distance (number of bits) between encoded values that can change without causing a
decode into the wrong value.
Handshake Packet:
A packet that acknowledges or rejects a specific condition. For examples, see ACK and NAK.
HDML:
Handheld Device Markup Language. HDML uses hypertext transfer protocol (HTTP) to display text
versions of web pages on wireless devices. Unlike WML, HDML is not based on XML. HDML does not allow
scripts, while WML uses a variant of JavaScript. Web site developers using HDML must re-code their web pages in
HDML to be viewed on the smaller screen sizes of handheld devices.
HARP:
Windows CE standard development platform spec (Hardware Adaptation Reference Platform)
High-bandwidth endpoint:
A high-speed device endpoint that transfers more than 1024 bytes and less than 3073
bytes per microframe.
High-speed:
USB operation at 480 Mb/s. See also
low-speed and full-speed
.
Host :
The host computer system where the USB Host controller is installed. This includes the host hardware
platform (CPU, bus, and so forth.) and the operating system in use.
Host Controller:
The host’s USB interface.
Host Controller Driver (HCD):
The USB software layer that abstracts the Host controller hardware. The Host
controller driver provides an SPI for interaction with a Host controller. The Host controller driver hides the
specifics of the Host controller hardware implementation.
Host Resources:
Resources provided by the host, such as buffer space and interrupts. See also
Device Resources
and Universal Serial Bus Resources
.
HSTL:
High-speed transceiver logic
Hub:
A USB device that provides additional connections to the USB.
Hub Tier:
One plus the number of USB links in a communication path between the host and a function.
