Introduction
1.7 Terminology
Table 1-1. Terminology (Sheet 1 of 3)
Term Description
ASPM Active State Power Management
Cbo
Caching Agent (also referred to as CA). It is a term used for the internal logic
providing ring interface to LLC and Core. The Cbo is a functional unit in the
processor.
DDR4 Fourth generation Double Data Rate SDRAM memory technology.
DMA Direct Memory Access
DMI3 Direct Media Interface Gen2 operating at PCI Express 3.0 speed.
DSB Data Stream Buffer. Part of the processor core architecture.
DTLB Data Translation Look-aside Buffer. Part of the processor core architecture.
DTS Digital Thermal Sensor
Enhanced Intel
SpeedStep
®
Tech n olog y
Allows the operating system to reduce power consumption when performance is
not needed.
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 overrun vulnerabilities and can thus help improve the overall
security of the system. See the Intel
®
64 and IA-32 Architectures Software
Developer's Manuals for more detailed information.
Functional Operation
Refers to the normal operating conditions in which all processor specifications,
including DC, AC, system bus, signal quality, mechanical, and thermal, are
satisfied.
GSSE
Extension of the SSE/SSE2 (Streaming SIMD Extensions) floating point
instruction set to 256b operands.
HA Home Agent (HA)
ICU Instruction Cache Unit. Part of the processor core architecture.
IFU Instruction Fetch Unit. Part of the processor core.
IIO
The Integrated I/O Controller. An I/O controller that is integrated in the
processor die.
IMC
The Integrated Memory Controller. A Memory Controller that is integrated in the
processor die.
Integrated Heat Spreader
(IHS)
A component of the processor package used to enhance the thermal
performance of the package. Component thermal solutions interface with the
processor at the IHS surface.
Intel
®
64 Technology
64-bit memory extensions to the IA-32 architecture. Further details on Intel 64
