When it comes to chip giants Intel, every Internet user should not be unfamiliar, Intel's CPU manufacturing technology is global, but do you know how the giant company made its fortune?
As of June 8, 1978, Intel has released a new microprocessor, "8086". The processor didn't get much attention w
first from Microsoft, although the previous Microsoft has launched the Surface Book, but only the i5 processor version, this time Microsoft formally for surface to add i7 processor version, appears to be a comprehensive performance upgrade.
And just after Microsoft released Surface Book i7 one day, Apple also launched 2016 MacBook Pro, and the new MacBook Pro release has been the focus of global users. Be
no interest in hardware technology know the microprocessor, at least the name of the processor. On the other hand, with the development of science and technology, the processor becomes extremely complex, and its construction and usage skills are difficult to be widely recognized.
However, is to understand the structure of the processor and operating principle, or to use it as a black box and do not know why, the use of the effect is no different. Lik
Recently developed on the Linux QT, found that the program exception crash, with the core dump file also did not record the useful information, the following figure:
Locator abnormal crash process of pain, although the final is to use the core dump file size limit cancellation, complete logging program crash stack information with GDB to locate the problem, but found that users share without core-dump location bug, so record down, for future trial.

technology to contend with AMD, but also add some new elements. The Nehalem architecture was launched last November for high-end desktops, with the first chips named Core i7 priced at $999. But Intel introduced a cheaper product for mainstream users in Monday, at a price ranging from 284 to 562 dollars, with a product priced at only $196. The introduction of these products has led to a further increase in the pressure on AMD.
At the same time, Intel
be as accurate as possible, in order to ensure easy to understand, may not reach the academic level of accuracy.3) This post emphasizes knowledge and understanding. And in reality, is to spend six hundred or seven hundred to buy a i3, or 1000 buy a i5, the specific situation of the specific analysis, there is no fixed answer.4) If it is local tyrants, just a ' cool ' word. Do not seek cost-effective, only the most expensive. This post is not recommended to read, because all the theory can not e

It is a "device" that can work independently ".Embedded systems include almost all electrical equipment in life, such as PDAs, mobile computing devices, TV set-top boxes, mobile Internet access, digital TVs, multimedia, automobiles, microwave ovens, digital cameras, home automation systems, elevators, air conditioners, security systems, vending machines, cellular phones, consumer electronic devices, industrial automation instruments, and med

Let's take a picture of the Architecture first.
ARM microprocessor Series
ARM microprocessor currently includes the following series, as well as other manufacturers based on the ARM architecture of the processor, in addition
In addition to the common features of the ARM architecture, each series of ARM
dominated by 32-bit CPU cores. The CPU cores designed by arm are commonly known as "ARM chips ", however, strictly speaking, an ARM chip should be a single-chip microcomputer designed with the CPU core of the arm. An SoC chip made with the CPU core of the arm is generally not called an ARM chip.Therefore, the ARM chip mentioned by the landlord is an advanced general-purpose microcontroller.DSP = digital signal processing, that is, digital signal processing. Like "Arm chip", "DSP chip" is common

One:CISC (Complex instruction Set computer) complex instruction computer CISC is the basic processing part of a desktop computer system, and the core of each microprocessor is the circuit that runs the instruction. A command consists of multiple steps to complete a task, transferring the value into a register, or adding an operation. CISC is a microprocessor that executes a complete set of computer instruct
[From: an in-depth understanding of Linux kernel]
Linux tries to keep a clear line between hardware-independent source code and hardware-related source code. To achieve this, the arch and include directories contain 23 sub-directories to correspond to different hardware platforms supported by Linux. The standard names of these platforms are as follows:
Alpha
HP's Alpha workstation was first owned by digital, and later belongs to Compaq, which is no longer produced.
Arm, arm26

In microcomputer, also known as microprocessor, all the operation of computer is controlled by CPU, the performance index of CPU directly determines the performance index of microcomputer system, what is the difference between Intel Core i3 and I5CPU?
Intel Core i3 can be seen as a further lite version of the Core i5, and will have a version of the 32NM process version (developed with Code Clarkdale, based on Westmere architecture). The biggest featu

According to the microprocessor (CPU) Word length classification by the microprocessor, the microcomputer is generally divided into 4-bit, 8-bit, 16-bit, 32-bit and 64-bit machine.(1) 4-bit microcomputer; 4-bit word-length microprocessor is a CPU, its data bus width is 4 bits, and one byte is divided two t
competitive in this rapidly growing market. However, users benefit from low prices. Many of the structural features of early PCs remain in modern PC systems. For example, Intel's most advanced Pentium Pro processor retains the Intel 8086 addressing model. When Linus Torvalds started to write Linux, he chose Intel 80386 PC, which was the most widely used and reasonably priced at the time.. 1 typical PC motherboard. From the outside of the PC, the most striking is the chassis, keyboard, mouse and
, it consists of analog signal conditioning circuit, A/D conversion circuit, display circuit and 485 communication circuit. The signal must be processed before it enters the/D converter. analog signal processing is one of the important factors affecting the system performance. signal quality should be taken into consideration during design to improve the signal-to-noise ratio and minimize distortion. In the design, the potentiometer is used in the conditioning circuit for fine-tuning, and the vo

Generally speaking, measuring a two-in-one equipment is good or bad, mainly to look at the design and specifications. After all, if you don't like the way they are deformed, then what is the meaning of the two oneness? So want to know Lenovo Yoga 910 and Microsoft Surface Book i7 who is better, we might as well

Both Microsoft and Lenovo have recently updated their new two-in-all-in-one hybrid notebook, which also shows that the hybrid device is currently in the market with very high popularity. While Microsoft Surface Book i7 and Lenovo Yoga 9,102 new products are mixed devices, but the two in the form of "mixed" is completely different. Lenovo Yoga 910 uses a more traditional 360-degree flip screen hinge d
