GLOSSARY
Copyright 2001 GLOSSARY-1 DAC128V HARDWARE REFERENCE
[x:y] ---------------------------------- Nomenclature designating a bit-range, where “x” is the left-most bit and
“y” is the right-most bit. (e.g. Data bus [7:0] refers to the Least
Significant eight bits).
ATE ---------------------------------- automatic test equipment.
byte-lane ---------------------------- 8-bits of a data bus on octal boundaries.
CAE---------------------------------- Computer Aided Engineering.
DAC --------------------------------- Digital-to-Analog Converter.
doublewide ------------------------- An IP Module that is twice the size of the singlewide board.
EPLD -------------------------------- Erasable Programmable Logic Device.
ID PROM --------------------------- The circuitry that presents the proper data patterns to the low 8-bits of
the IPDbus, with upper-byte zero fills, during the ID (read) transfers.
IP Module--------------------------- Business-card size mezzanine-type subsystems designed with a common
digital interface known as the IP bus. An open industry standard defines
the mechanical and electrical interface to the carrier board.
I/O ------------------------------------ Input/Output.
IP Module logic bus -------------- A synchronous, 8 MB/sec, 16-bit wide bus that includes I/O, memory, ID
PROM, interrupts. The address bus is 6-bit wide, except in memory
mode. Then the data bus is multiplexed for the upper portion of the
address bus, resulting in 22 bits of address. This results in up to
4 Mwords of memory space per IP Module.
IPDbus------------------------------- IP Module Data Bus.
LRU---------------------------------- Line-replaceable units.
MTBF ------------------------------- Mean Time Between Failures.
ns,
µ
s, ms --------------------------- Nanoseconds, Microseconds, and Milliseconds, respectively.
singlewide -------------------------- An IP Module printed circuit board (3.9" by 1.8"). Each module has two
50-pin connectors.
VHDL ------------------------------- Very high speed integrated circuit Hardware Description Language.
