Execute Disabled Bit
Execute Disable Bit (EDB) is a hardware-based security feature that introduced to its new generation
CPU by Intel, which can help reduce system exposure to viruses and malicious code. EDB allows
the processor to classify areas in memory where application code can or cannot execute. To use
Execute Disable Bit you must have Windows XP SP2 operating system to support this function.
Intel Virtualization Technology
Intel virtualization technology enables to run multiple O/S of the same kind or different kind by using
the same physical platform so as to realize the management and allocation of computer resources,
maximizing the resource utilization.
Hardware Prefetcher
Whether the processor allows the Intel hardware prefetcher to fetch streams of data and instruction
from memory into the unified second-level cache when necessary. This can be one of the following:
Disabled—The hardware prefetcher is not used.
Enabled—The processor uses the hardware prefetcher when cache issues are detected.
Adjacent Cache Line Prefetch
Whether the processor fetches cache lines in even/odd pairs instead of fetching just the required line.
This can be one of the following:
Disabled—The processor only fetches the required line.
Enabled— The processor fetches both the required line and its paired.
