words and concepts
Before proceeding, it is necessary and important to define a common "term. Therefore, at the beginning of this article, the author will first describe the VMware term used in this article. This does not help you compile this article, but is also the first step for you to understand VMware. In addition, in order to make it easy for you to provide a clear description of VMware software and its English language (including information and explanatory documents), the author will c
7.2 hardware prefetch of data
Pentium M, Intel Core solo, Intel Core Duo processors, and Intel Core micro-architecture-based intel netburst processors provide hardware data prefetch mechanisms, this mechanism monitors the application data access mode and automatically fetches data. This action is automatic and does not require programmer intervention.
For intel netburst-based processors, the features of the hardware data prefetch include:
1. It needs
Note: The following are the first generations of Pentium 4 series products: Willamette core launched in 1.3, nm, clock speed ~ 2.0 GHz, pins 423 or 478,Supported chipset: Intel i845 (478)/i850 (423), via p4x266, and other second generation: The Northwood core launched in 02 years, with a clock speed of 1.8-nm ~ 3.06 GHz, pin 478,Supported chipsets include Intel i845, 848/865, 875, and other third generations: The Prescott core launched in 2.4, with a

When we use-O9 to compile programs, the number of file bytes may be the largest, but the speed is usually the fastest. Depending on the machine architecture, you can add the following statement to/etc/profile.

implemented, each processor by sniffing the data propagated on the bus to check whether the value of its cache is expired, when the processor found its own cache line corresponding memory address is modified, The cache line of the current processor is set to an invalid state, and when the processor modifies the data, it will re-read the data from the system memory into the processor cache. The two implementation principles of volatile:1) The lock prefix instruction causes the processor cache t
VMware Virtual Machine vxwoks5.5 entire process2011-06-22 10:06:51| Category: VMware related | Report | Font size Subscription Recently in the study of VxWorks, to run on the VMware virtual Pentium processor on the VxWorks, so on the reference online Daniel's documents, but in some key place to pass, so extensive search information, cost a lot of effort finally put VxWorks entreat to the virtual machine. In order to avoid the first entry into t
, so when everyone installed, the most encountered or Intel platform. Because of Intel's different generation of CPUs, often because of the changes in the interface, and the use of different series of motherboards, so in the CPU and the motherboard to match, be sure to be aware of compatibility.
Intel's CPU and motherboard introduction
Intel processor product models are numerous, usually by generation with the motherboard, here This article does not discuss those who have been eliminated the o
® Pentium G3258
Spec.: 2 processor cores, power consumption 53W, integrated Intel HD Graphics graphics control chip, clock frequency 3.2GHz, processor slot LGA 1150, two cache 2 x 256KB.
Advantages: overclocking potential is amazing, low power consumption
Disadvantage: A new motherboard may be required.
There are also inexpensive Intel processors on the market, such as Celeron G1840. But in the low-end market,
than a single core processor. If you want only the original clock speed, you should buy the fastest processor you can find. Intel's fastest single core boxed processor is the 3.8GHz Pentium 4 model 670 and 3.6GHZ Pentium 4 model 660. The current fastest dual-core processor is 3.2GHz Pentium D 840. (a 3.6GHz dual-core Pentium
Once high cost performance G620 processor +h61 Motherboard became a classic entry-level platform, but with the advent of the G620 processor upgrade G630, it seems to be breaking the situation, G630 processors have better performance, and the price is equivalent to the increase of no increase in products, Therefore, the current installation of the author think that the introduction of cost-effective G630 platform is worth recommending, the following computer technology for everyone to recommend d

The 3D gaming performance of entry-level computers is limited, AMD and Intel's set contrast is 50-step laugh 100 Steps, so this level of configuration more value computing power and stability. To be comprehensive, the entry-level configuration is a good choice based on the Intel-proven Pentium G620 processor and the H61 motherboard. In addition APU highly integrated configuration is also a good choice. Today, the editor first recommended a 2800-yuan u
