Microprocessor
The PC3-ALLEGRO is equipped with Intel® Core
TM
i7 or i5 3
rd
generation mobile ECC processor (code
name Ivy Bridge). These low power processors provide integrated graphics and memory controller,
which results in a very efficient platform design. The Core
TM
processors almost can be considered as
a single-chip solution, since all functions of a typical north-bridge have been moved to the CPU.
The Core
TM
i7 and i5 processor 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 PC3-ALLEGRO are running at core clock speeds up to 2.1GHz for
quad core and up to 2.5GHz on dual core devices. Due to Enhanced Intel® SpeedStep® and Intel®
Turbo Boost Technology each core can decrease or increase its nominal operating frequency. The
clock speed 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-7 voltage regulator specification.
