3 Functional Description
The following sections describe the cPCI-3920 main functions and
board interfaces.
3.1 CPU, Memory and Chipset
CPU: Intel® Core™ Duo and Intel® Core™2 Duo
The cPCI-3920 supports the latest Intel® Core™ Duo and Intel®
Core™2 Duo processor family up to speeds of 1.5 GHz with up to
667 MHz FSB. The Intel® Core™ Duo consists of two cores and
up to 2 MB L2 cache shared by both cores. The Intel® Core™2
Duo consists of two cores, up to 4 MB L2 cache shared by both
cores, Intel Extended Memory 64 Technology (Intel EM64T), and
enhanced address range for up to 64 GB memory. The Intel®
Core™ Duo and the Intel® Core™2 Duo processors deliver opti-
mized power-efficient computing and outstanding dual-core perfor-
mance with low power consumption.
The Intel® Core™ Duo and the Intel® Core™2 Duo support the
latest Intel’s Virtualization Technology (VT), which allows a plat-
form to run multiple operating systems and applications in inde-
pendent partitions, such as performing system upgrades and
maintenance without interrupting the system or the application,
keeping software loads and virus attacks separate, combining
multiple servers in one system, etc. With processor and I/O
enhancements to Intel’s various platforms, Intel Virtualization
Technology improves the performance and robustness of today’s
software-only virtual machine solutions.
Furthermore, the Intel® Core™ Duo and the Intel® Core™2 Duo
also support the Intel SpeedStep technology which enables real-
time dynamic switching of the voltage and frequency between sev-
eral modes. This is achieved by switching the bus ratios, core
operating voltage, and core processor speeds without resetting
the system.
