SBCs cut speed to save power
To meet customer demands for even lower power dissipation Concurrent Technologies now supports Enhanced Intel SpeedStep Technology on its range of VME and CompactPCI single-board computers.
To meet customer demands for even lower power dissipation Concurrent Technologies now supports Enhanced Intel SpeedStep Technology on its range of VME (VP 305/01x) and CompactPCI (PP 310/01x) single board computers, including extended operating temperatures By using the Intel Pentium M processor they allow a system designer to have greater control over the thermal and power characteristics of the board

Concurrent Technologies has brought out a Gigabit Ethernet switch board, the FP 210/024, to operate alongside its range of VMEbus-based single board computers.
CompactPCI storage mixes HDDs and CompactFlash
Enables the integration of SATA300 mass storage drives into a 3U CompactPCI system, where performance, functionality, power, space and cost are key elements.
Tests on Concurrent Technologies boards show benefits, when stepping a 1.6GHz board down to 600MHz, 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 preset 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 1.6GHz processor has six different frequency points ranging from 1.6GHz down to 600MHz.
Unlike legacy versions of Intel SpeedStep Technology, which required hardware support through the chipset, the software model now provides a centralised 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 250 to 10us; the software can perform a frequency/voltage state transition by simply writing to one register.
Concurrent Technologies VME and CompactPCI single board computers, using the Intel Pentium M processor, can support a variety of operating systems that use the software model behind Enhanced Intel SpeedStep Technology.
Concurrent Technologies single board computers currently using a 1.6 or 1.1GHz Intel Pentium M processor are: the PP 310/01x family - a dual PMC CompactPCI SBC; and the VP 305/01x family - a single PMC VME SBC.
