2.1.1
CPU
The CP307 supports the latest Intel® Core™ Duo and Intel® Core™2 Duo processor family up
to speeds of 2.16 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, In-
tel® 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 performance with low power con-
sumption.
The Intel® Core™ Duo and the Intel® Core™2 Duo support the latest Intel’s Virtualization
Technology (VT), which allows a platform to run multiple operating systems and applications in
independent partitions, such as performing system upgrades and maintenance without inter-
rupting the system or the application, keeping software loads and virus attacks separate, com-
bining 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 fre-
quency between several modes. This is achieved by switching the bus ratios, core operating
voltage, and core processor speeds without resetting the system. The frequency for the pro-
cessor may also be selected in the BIOS or via the operating system.
The following list sets out some of the key features of the Intel® Core™ Duo and the Intel®
Core™2 Duo processors:
• Two mobile execution cores in one single processor
• Support of Intel’s Virtualization Technology (Vanderpool)
• Support of Intel Architecture with Dynamic Execution
• Outstanding dual-core performance with low power consumption
• On-die, primary 32 kB instruction cache and 32 kB write-back data cache
• On-die, L1 and L2 cache with Advanced Transfer Cache Architecture
• Intel® Core™ Duo processor U2500 (ULV), 1.2 GHz, 533 MHz FSB, 2 MB L2 cache
• Intel® Core™ Duo processor L2400 (LV), 1.66 GHz, 667 MHz FSB, 2 MB L2 cache
• Intel® Core™ Duo processor T2500 (SV), 2.0 GHz, 667 MHz FSB, 2 MB L2 cache
• Intel® Core™2 Duo processor L7400 (LV), 1.5 GHz, 667 MHz FSB, 4 MB L2 cache
• Intel® Core™2 Duo processor T7400 (SV), 2.16 GHz, 667 MHz FSB, 4 MB L2 cache
• Advanced Branch Prediction and Data Prefetch Logic
• Streaming SIMD Extensions 3 (SSE3)
• Up to 667 MHz, Source-Synchronous Front Side Bus (FSB)
• Advanced Power Management features including Enhanced Intel® SpeedStep® tech-
nology
• Intel® Extended Memory 64 Technology for 64-bit computing (only with the Intel®
Core™2 Duo)
