Like mathematicians in solving the famous Goldbach conjecture, although there is no final solution to the problem, but in the course of the birth of many famous books related to number theory.Recommended reference BooksAlthough the compilation theory has developed to today, has already had the relatively mature part, but as a university student, must write a kind of compiler like Turboc C,java is still too difficult. Not only is it difficult to write compilers,

is that the school teachers speak more, the basic work is not used, and the teacher did not speak, or speak relatively little, the work is often used more. For example, in C language, the pointers, the structure of these, the school has little or no depth, we do not pay attention to, but to deal with the exam, but the work we need to always deal with them. Did you say you were a good study?
This, in part, reflects the fact that there is a serious disconnect between school education and social

Marvell, this semiconductor company has developed too fast over the past few years. It has acquired an Intel hardware department and a wireless chip Department of UT. By the way, the founder of Marvell is a ** Chinese and a Shanghai girl, a strong man. It really gives a long face to t
microcomputer, it is internationally referred to as Microcontroller (MCU, UC), is the central processor CPU, Random Access to Memory RAM (usually store random data ), read-only memory Rom (usually solidified to store user programs), input/output port I/O and other major computer functional components, are integrated into a chip (chip also known as integrated into IC, integrated circuit ), thus forming a conceptual and complete microcomputer.

, tools are far behind platforms. We are currently using the latest platform technologies (for example, by using music to write services, we can now automate processes among multiple enterprises located anywhere on this planet ), but we are still writing every application manually, as if this is the preferred method. We start with a small concept (such as loop, string, and integer) to create a large abstract concept (such as insurance claims and securities trading ). We work diligently and metic
inverter is called "torque boost" (* 1 ).The torque increase function is to increase the output voltage of the inverter. However, even if a lot of output voltage is increased, the motor torque cannot be correspondingly increased with its current. Because the motor current contains the torque and other components (such as the excitation component) produced by the motor )."Vector Control" allocates the current value of the motor to determine the current component of the motor generating torque an
Power Management (or energy consumption management) is a research topic for chip design, manufacturing process, system design, and software, we strive to minimize static and dynamic power consumption in each phase. The traditional voltage control and management standby modes are still being adopted by most electronic devices and will continue. However, with smart phones, navigation devices, and wireless sensor network devices, with the rapid increase in the market scale of devices that consume a
The MoS tube name comes from the English name Metal (metal), OXID (oxide), semiconductor (semiconductor), is a field-effect transistor, or a semiconductor called a metal insulator. Usually the FET (field effect tube) is generally used as a thin layer of silica as the insulator under the gate, so the usual MOS tube size is smaller than the ordinary bipolar trans

The fast, powerful, and accurate algorithms of this software are suitable for the demanding applications of the semiconductor and electronics manufacturing industries.General Features• User-selectable algorithms (region-base
Read-Only Memory (ROM) is a kind of semiconductor Memory, which features that it cannot be changed or deleted once data is stored. It is usually used in electronic or computer systems that do not need to change data frequently. The data will not disappear because the power supply is off. For example, early PCs such as Apple II or ibm pc xt/AT boot programs (operating systems) or Firmware in various other microcomputer systems ). Only Solid-state
Chip on board (COB)
Thermal conductive epoxy resin (Generally, silver-doped epoxy resin is used) to cover the placement point of the silicon wafer. Then, the silicon wafer is directly placed on the substrate surface and heat treated until the silicon wafer is firmly fixed to the substrate, then, the SI welding method is used to directly establish an electrical connection between the silicon wafer and the substrate. The bare chip technology has two main forms: COB technology and flip chip ). On-

When the computer is powered on, the BIOS will check all its internal devices for self-check, including testing of CPU, memory, read-only memory, system motherboard, CMOS memory, parallel and serial communication subsystem, floppy disk and hard disk subsystem, and keyboard. After the self-check test is completed, the system searches for the operating system in the specified drive and installs the operating system into the memory. What is binary CMOS? BIOS is stored in C

Arm dared to be the first in the world. 12 years ago, It pioneered the chipless production model. That is, the company neither produces nor designs chips, but designs an efficient IP core and authorizes semiconductor companies to use it, semiconductor companies add their own design and launch chip produc
