on), the linear address space is divided into a series of pages and mapped to virtual addresses, and subsequent pages of the virtual memory map the corresponding physical memory as needed. The paging mechanism is transparent to the application when the page is used by the operating system or an executable program. All applications look at the linear address space.In addition, the paging mechanism of IA-32 includes some extension functions:

architecture processors is enormous, and a new L3 cache design will make k8l architecture processors more than twice times faster than the K8 architecture processor, and will be more than 40% higher than the core architecture, making a significant contribution to the overall performance of the CPU.
On the other hand, the memory system of the K8L architecture will support DDR3 memory and FB-DIMM standards,
and expansion, but now the price of this machine is also relaxed, and now it is only 13500 yuan. If you are interested, you can consider it.
HP ProLiant DL380 G5 (470064-635) uses a dual-circuit design. The motherboard has two CPU slots, but the standard quantity is one. It uses a quad-core Intel Xeon E5405 processor, which uses a 45nm process, the performance

In fact, it is not original. The materials are mostly from the Internet through Google.
Some time ago I bought a hp-dv1702 laptop, core Single Core CPU, 5400 turn hard disk, watch a movie very good. the core
Many people in the process of using a notebook, often pay attention to their CPU performance, we will see the notebook CPU model behind the usual "U", "M" and other words, and "u" is the meaning of low pressure, "M" is the meaning of the standard pressure. Recently, a lot of net users of notebook CPU low-voltage and high-pressure difference is not very understand
types, the common is HQ, MQ, XM and so on. The specific meaning is as follows:
HQ represents the four-core processor directly welded to the motherboard and cannot be replaced;
MQ represents the BGA package four core processor, and desktop processor card in the CPU slot, if the user found a suitable replacement, you can replace, but pay attention to the heat co
Heat dissipation problem that's one of the biggest drawbacks of laptops. The ideal temperature of the notebook is higher than the ambient temperature of about 30 degrees, so we can use the environment to judge according to their own computer.
But in fact, notebook temperature is not ideal, at this time you should pay attention to control the notebook CPU temperature within 75 degrees----75 degrees is the CPU
Interactive, a market research firm, shows that 48% of PC users are still at a loss about what the dual-core is after AMD has announced its Opteron plan for nearly three years. (Of course, within the industry is another case.) Data center managers and corporate CIOs are well aware of the capabilities that dual-core computing can bring to the enterprise. )
In a survey of home users, 42% of personal-compute

A recent study of virtualization technology inevitably encountered a problem: how to evaluate the capacity of virtual hosts on physical hosts? The ideas in the following article are enlightening.
How to determine the number of virtual machines deployed on a CPU core?
Abstract:This article describes the ideal number of virtual machines deployed on a CPU
example, No. 0, 1: mask=0x031th, 2: mask=0x06And so onIf the number of CPUs is insufficient, a modulo operation is performed. For example, a total of 4 CPUs, then mask=0x0010 and 0x01 the same.The advantage of this method is that multi-threading does not have to manually select the CPU each time, the disadvantage is that in the event of a high CPU load, then the program execution speed is slow (think alike
Dual core or qua core is very popular now, so everyone should understand the Cortex-A9 in the end. Cortex-A8 is a bit past in smartphone, Cortex-A9 is very popular now, but the real blockbuster application, expert prediction in 2013 ~ 2014. This articleArticleIs I reprint a cattle people abroad on the Cortex-A9 new feature summary, very useful.
