1.1.1 Processor Packaging Terminology
Commonly used terms are explained here for clarification:
• Intel Celeron Processor 200 Sequence — Single core processor in the FC-BGA6
package with a 512 KB L2 cache.
• Processor — For this document, the term processor is the generic form of the Intel
Celeron processor 200 sequence. The processor is a single package that contains
one exectution unit.
• Keep-out zone — The area on or near the processor that system design can not
use.
• Processor core — Processor core die with integrated L2 cache.
• FSB (Front Side Bus) — The electrical interface that connects the processor to
the chipset. Also referred to as the processor system bus or the system bus. All
memory and I/O transactions as well as interrupt messages pass between the
processor and chipset over the FSB.
• Storage conditions — Refers to a non-operational state. The processor may be
installed in a platform, in a tray, or loose. Processors may be sealed in packaging or
exposed to free air. Under these conditions, processor pins should not be connected
to any supply voltages, have any I/Os biased, or receive any clocks. Upon exposure
to “free air”(i.e., unsealed packaging or a device removed from packaging material)
the processor must be handled in accordance with moisture sensitivity labeling
(MSL) as indicated on the packaging material.
• Functional operation — Refers to normal operating conditions in which all
processor specifications, including DC, AC, system bus, signal quality, mechanical
and thermal are satisfied.
• Execute Disable Bit — The Execute Disable bit allows memory to be marked as
executable or non-executable, when combined with a supporting operating system.
If code attempts to run in non-executable memory the processor raises an error to
the operating system. This feature can prevent some classes of viruses or worms
that exploit buffer over run vulnerabilities and can, thus, help improve the overall
security of the system. See the Intel
®
Architecture Software Developer's Manual
for more detailed information.
• Intel
®
64 Architecture — An enhancement to Intel's IA-32 architecture, allowing
the processor to execute operating systems and applications written to take
advantage of the Intel
®
64 architecture. Further details on Intel
®
64 architecture
