Chapter 6: Glossary
Advanced Dynamic Execution
Part of the Pentium® 4 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.
