| Battery life
and specifically power management of the Intel®
Centrino™ system can be optimized via
hardware, software, or firmware. These elements
work together to balance power usage and
performance for a notebook system.
Many elements required to
extend battery life are implemented directly
into the processor, chipset, and wireless
components of Intel® Centrino™ Mobile
Technology. Power is conserved through the
following hardware features and technologies:
 | Micro-Ops Fusion:
10% fewer Micro-Ops resulting in faster
execution at lower power. |
| Dedicated Stack
Manager:
Greater than 5% fewer Micro-Ops. The processor
employs sophisticated hardware control for
stack management and implements a
synchronization mechanism to eliminate power
hungry micro-ops. |
| Power-Optimized
Processor System Bus:
The Intel Pentium® M processor has the lowest
PSB voltage ever! Lower power from low voltage
and fewer pins results in more de-powering
capability. |
| Dynamic core
frequency switching (100/133/200 MHz ): |
| Optimized internal
clock gating for 3D and display engines:
Another low
power feature where we do not clock the 3D or
display engines unless they are required. This
lowers chipset power. |
| Dynamic I/O buffer
disabling for Intel Centrino Mobile Technology
PSB/Mem:
Dynamic Buffer disabling for both Processor
System Bus and memory intelligently reduces
signaling on these interfaces resulting in
lower chipset power consumption. |
