64-bit technology

Intel believes that the four Nocona technologies included in DBS, PCI-E, EM64T, and DDR2 are the real entry barriers to 64-bit.

EM64T technology includes CPU and memory 2 technology, is Intel's EM64T technology CPU is an extended, 32-bit compatible 64-bit processor. Currently, only Intel Xeon processors with an 800MHz front-side bus support EM64T. Because operating systems and application software are not yet fully transitioning to 64-bit, the hardware platforms offered today are not only 64-bit but also 32-bit compatible. In the near future, users will enjoy this true 64-bit application when the operating system and application software are both 64-bit. Memory for Intel's EM64T technology is a new technology that enhances servers and workstations with 64-bit addressing and associated instructions.

Under the following conditions, 32-bit and 64-bit modes are available, and 32-bit applications can still be run on Intel processors with Intel Extended Memory 64 Technology!

In fact, the realization of true 64-bit technology is not only dependent on the hardware manufacturers, but also requires the synchronization of the operating system vendors; operating system manufacturers are ready, but also need the 64-bit ISV (independent software developers). Only these three parties are ready to implement true 64-bit applications. Now a large number of applications are still on the 32-bit, Intel introduced EM64T, it can be said is a smooth transitional platform. The current situation is that the operating system and application software that users run are mostly 32-bit, which can exert its limits on the EM64T and show the best level; when the operating system and applications have 32-bit and 64-bit coexistence, It can also break the 32-bit limit and run both software on one machine; when the operating system and applications all transition to 64-bit, users can enjoy all 64-bit applications.

DBS technology
DBS technology is Demand-Based Switching on-demand technology. The DBS technology on-demand switching technology will flexibly adjust the CPU operating frequency and voltage according to the CPU load. When the load is relatively small can be adjusted to a relatively low voltage, such as the frequency of 1.2 volts, when the requirements are relatively high, you can work at a more voltage. This mode of on-demand CPU switching also makes the entire platform flexible and adjustable. At the same time, more storage technologies will be applied to the new generation of platforms. Both SATA and SCSI storage modules can support hot-swappable SATA RAID 5 and hot-swappable SCSI RAID 5. Both storage modules can be flexibly swapped. Easy to choose. The flexible and replaceable memory module also brings more flexibility and convenience to the user's application.
