Chapter 7: Glossary
Advanced Dynamic Execution
Part of the Xeon processor's Intel® NetBurst® micro-architecture. Improved branch prediction
algorithm accelerates the flow of work to the processor and helps overcome the deeper
pipeline. Very deep, out-of-order speculative execution allows the processor to view 126
instructions in flight and handle up to 48 loads and 24 stores in the pipeline. A 4 KB branch
target buffer stores more detail on the history of past branches, reducing inaccurate branch
predictions by roughly 33% (when compared to P6 micro-architecture).
Advance Transfer Cache (Level 2 Advance Transfer Cache)
The 256 KB Level 2 Advance Transfer Cache (ATC) delivers a much higher data throughput
channel between the Level 2 cache and the processor core. 512 KB L2 Advance Transfer
Cache is available on 0.13 micron technology Pentium® 4 processors, while 0.18 micron
technology Pentium 4 processors utilise a 256 KB L2 Advance Transfer Cache. Features of the
ATC include: Non-Blocking, full speed, on-die level 2 cache, 8-way set association, 512-bit or
256-bit data bus to the level 2 cache, data clocked into and out of the cache every clock cycle.
BIOS
(Basic Input Output System) This is software stored on a chip and consists of the instructions
necessary for the computer to function. The System BIOS contains the instructions for the
keyboard, disk drives etc., and the VGA BIOS controls the VGA graphics card.
CPU
Central Processing Unit. This is the main piece of equipment on the Motherboard. The CPU
processes data, tells memory what to store and the video card what to display.
Default
The configuration of the system when it is switched on or the standard settings before any
changes are made.
DIMM
Dual In-Line Memory Module, a type of memory module used for the systems main memory.
Driver
A piece of software which is used by application software to control some special features. Each
graphics board and printer requires its own driver.
D-Type
A common type of connector used for connecting printers, serial ports, game port, and many
other types of interface.
DRAM
Dynamic Ram used for main system memory, providing a moderately fast but cheap storage
solution.
