May 2004 –To meet customer
demands for even lower power dissipation Concurrent
Technologies now support Enhanced Intel® SpeedStep® Technology
on their range of VME (VP 305/01x) and CompactPCI® (PP
310/01x) single board computers, including extended operating
temperatures. By utilizing the Intel® Pentium® M processor
they allow a system designer to have greater control over the
thermal and power characteristics of the board. Tests on
Concurrent Technologies boards show benefits, when stepping a
1.6 GHz board down to 600 MHz, of up to four times less +5V
current. Therefore, depending on the application requirements,
the processor frequency operating point of a Concurrent
Technologies Intel Pentium M processor board can be pre-set in
the BIOS, or controlled dynamically via the application’s
operating system.
Enhanced Intel SpeedStep
Technology enables the system software to control the
processor’s operating frequency and input voltage. For
example, the 1.6 GHz processor has 6 different frequency
points ranging from 1.6 GHz down to 600 MHz. Unlike legacy
versions of Intel SpeedStep Technology, which required
hardware support through the chipset, the software model now
provides a centralized implementation that enables the
software to access the processor and its voltage regulator
without using the chipset. This reduction in hardware and
improved software interface has reduced the processor core
unavailability time from 250μs to 10μs; the software can
perform a frequency/voltage state transition by simply writing
to one register.
Concurrent Technologies VME and
CompactPCI single board computers, utilizing the Intel Pentium
M processor, can support a variety of operating systems that
utilize the software model behind Enhanced Intel SpeedStep
Technology.
Concurrent Technologies single board computers currently
utilizing a 1.6 GHz or 1.1 GHz Intel Pentium M processor are…
