The Intel Core 2 Duo Ultra Low Voltage Processors are part of Intel's Core 2 Duo Mobile series. These processors limit its processing power even more than the Low Voltage Series to reduce the power used, but still it is in no way only a basic version of the Core 2 Duo series. These processors feature everything from Execute Disable Bit, to Enhanced Intel SpeedStep Technology. It uses new 64-bit architecture which enables twice the amount of information that the CPU can process at a time. The Core 2 Duo Ultra Low Voltage series also have Wide Dynamic Execution which improves the execution speed and efficiency of the processor, and Virtualization Technology which allows one computer to operate as multiple “virtual” platforms.
