Specifications

EPC-3305 Hardware Reference
112
FPGA
(Field Programmable Gate Array) A large, general-purpose logic device that is
programmed at power-up to perform specific logic functions.
FBD
(Flash Boot Device) A flash memory device containing the computer’s BIOS. In the
NY1210, a 1 MByte Intel 28F800B5 semiconductor flash memory containing the
system and video BIOS images, the BIOS initializing code and the recovery code
which allows self hosted reflashing.
Flash
Memory
A fast EEPROM semiconductor memory typically used to store firmware such as the
computer BIOS. Flash memory also finds general application where a semiconductor
non-volatile storage device is required.
Flash
Recovery
See BIOS Recovery.
Flash
Update
See BIOS Update.
Force
Update
See BIOS Recovery.
GB or GByte
(Gigabyte) Approximately one billion (US) or one thousand million (Great Britain)
bytes. 2^30 = 1,073,741,824 bytes exactly.
Hang
A condition where the system microprocessor suspends processing operations due to
an anomaly in the data or an illegal instruction.
Header
A mechanical pin and sleeve style connector on a circuit board. The header may exist
in either a male or female configuration. For example, a male header has a number
and pattern of pins which corresponds to the number and pattern of sleeves on a
female header plug.
h
(Hexadecimal) A base-16 numbering system using numeric symbols 0 through 9 plus
alpha characters A, B, C, D, E, and F as the 16 digit symbols. Digits A through F are
equivalent to the decimal values 10 through 15.
Host Bus
The address/data bus that connects the CPU and the chipset.
ISA
(Industry Standard Architecture) A popular microcomputer expansion bus
architecture standard. The ISA standard originated with the IBM PC when the
system bus was expanded to accept peripheral cards.
I/O
(Input/Output) The communication interface between system components and
between the system and connected peripherals.
IDE
(Integrated Drive Electronics) A hard disk drive/controller interface standard. IDE
drives contain the controller circuitry at the drive itself, as compared to the location
of this circuitry on the computer motherboard in non-IDE systems. IDE drives
typically connect to the system bus with a simple adapter card containing a minimum
of on-board logic.
IRDA or
IrDA
(Infra-red Data Association) A specification for high-speed data communication
using infrared drivers and receivers for short-range wireless data transmission.
INT
(Interrupt Request) A software-generated interrupt request.
IRQ
(Interrupt Request) In ISAbus systems, a microprocessor input from the control bus
used by I/O devices to interrupt execution of the current program and cause the
