CPU Board

Microprocessor

The PC1-GROOVE is designed for use with Intel® Core

i7 processors (code name Arrandale). These

processors integrate the graphics and memory controller within one chip that up to now were located

in an external part of the chipset (GMCH). As a result the platform core is reduced from the known

three chip solution (CPU, GMCH, ICH) to only two devices (CPU, PCH).

The Core

i7 family includes beside the Standard-Voltage (SV) also several Ultra Low-Voltage (ULV)

and Low-Voltage (LV) processors as listed below. The processors are housed in a Micro FC-BGA

package for direct soldering to the PCB, i.e. the chip cannot be removed or changed by the user.

The processors supported by the PC1-GROOVE are running at core clock speeds up to 2.53GHz. Due

to Enhanced Intel® SpeedStep® and Intel® Turbo Boost Technology each core can decrease or

increase its nominal operating frequency. The internal Core

i7 processor speed is achieved by

multiplying the host base frequency of 133MHz by a variable value. The multiplier is chosen

depending on the power states of the processor cores/graphics engine, the currently required

performance, and the actual core temperature.

Power is applied across the CompactPCI connectors J1 (3.3V, 5V). The processor core voltage is

generated by a switched voltage regulator, sourced from the 5V plane. The processor signals its

required core voltage by 7 dedicated pins according to Intels IMVP-6.5 voltage regulator specification.
