PFU Systems Inc. has announced a full suite of power management and thermal protection controls on its Plug-N-Run G3 System-on-Modules based on the Intel Pentium M processor and Intel 855GME chipset.

The suite of controls allows OEMs to build sophisticated and intelligent power management and thermal protection schemes for extended time-between-recharging in mobile equipment and for careful management of performance versus dissipation in high-density systems.

The controls are implemented in the latest release of the BIOS that is shipping on the 1.1GHz and 1.6GHz Plug-N-Run G3 production units, and will also ship with future speed grades of the Plug-N-Run G3 modules. The products are accessible through the BIOS setup and are used to configure operating ranges and behavior at different dissipation and performance levels of the Plug-N-Run G3 modules.

The BIOS setup provides control over CPU, graphics processor, memory and system I/O dissipation and performance. Latent Enhanced Intel SpeedStep technology available on the Pentium M processor can be selectively masked to meet a variety of criteria, and can be combined with dynamic CPU clock throttling to further lower the total power dissipation in power sensitive applications.

High and low frequencies can be selected for the operation of the graphics processor core as a function of DDR SDRAM memory speeds. Lower DDR SDRAM speeds can be selected to limit current consumption and dissipation. The suite of controls also allows the graphics core integrated in the 855GME chipset to be disabled for power-sensitive, deeply embedded applications. And I/O subsystems can be selectively switched off, such as LVDS transmitters, USB and IDE controllers, serial and parallel ports, and LAN controller.

The Plug-N-Run G3 BIOS also implements the thermal protection controls available on the Pentium M processors and 855GME chipset. These include the Intel Thermal Monitor Modes to automatically protect the CPU from thermal damage.
