Circuit bridge-chip contact with wire to the pin of the package shell, These pins also connect to other devices through the wires on the printed circuit board. As a result, encapsulation technology is a critical part of many integrated circuit products.At present, the CPU is packaged with insulating plastic or ceramic material, can play the role of sealing and improving the electric performance of the chip. As the processor chip's internal frequency
JAVA design pattern-abstract factory pattern
The previous chapter describes the factory method model. We know that there is only one abstract Product role in the factory method model, and the specific factory role corresponds to the specific product role one by one.
The difference between Abstract Factory roles and specific factory roles today is that abstract factory roles can have multiple abstract product roles, and each abstract Product role can have multiple specific product roles,

B. The ram resource is 400K-3888Kbit. Note that the size of the ram block is 9 Kbit. Some modules, such as fifo, actually do not use 9 K resources. However, no matter how much you use, you have to use one ram (in some cases, 0.5 ram is used ). Therefore, consider whether the number of ram instances is sufficient.
C. The number of multiplier numbers is 23. Note that it is a 18*18 bit multiplier. In actual use, it depends on the multiplier precision required by the application.

1. Scenario Simulation
Take a common example in our daily life: when assembling a computer, we usually need to select a series of accessories. For example, when selecting a CPU, pay attention to the brand, model, and number of pins, clock speed. Only when these values are determined can a CPU be determined. The same is true for the motherboard. For the installation engineer, he only knows that the relevant accessories are required to install a compute
1. Dip dual-row direct insert Encapsulation
Dip (dualin-line package) is an integrated circuit chip encapsulated in the form of Dual-row direct insertion. Most small-and medium-sized Integrated Circuits (IC) use this encapsulation form, generally, the number of pins cannot exceed 100. The CPU chip in dip package has two pins and needs to be inserted into the chip socket with dip structure. Of course, it c

Chapter 2 plug-in Analysis
Plug-ins are actually a collection of files. These files are stored on the client and loaded and run on the client. The available World of Warcraft custom plug-ins are already very rich. This chapter focuses on how the plug-ins are made up and explains each part.

Before writing a piece about the game engine design article, today uses the game engine to implement a small game (actually is not the strict meaning game), mainly is in order to feel the game engine to the game design to bring the convenience, but is not the game itself, after using the game engine you will discover, the game design will be much simpler. It gives you a framework, and all you need to do is fill in the content.Much to say, the following is the game engine in the game specific use

The CPU pins are the type of interface, and we know that the CPU needs to be connected to the motherboard through an interface to work. After so many years of development of the CPU, the use of the interface has a PIN type, cassette, touch-type, such as pin-type. The current CPU interface is a pin-type interface, corresponding to the motherboard on the corresponding slot type. CPU interface type is different, in the number of Jacks, volume, shape chan
Scenario Problems
A common example in our daily life is assembling a computer. When assembling a computer, we usually need to select a series of accessories, such as CPU, hard disk, memory, motherboard, power supply, and chassis. For the sake of simplicity, we only need to consider the choice of CPU and motherboard.
In fact, when selecting a CPU, there are a series of problems, such as the brand, model, number of pins, and clock speed. Only by determi

A 04031 error may occur in the share pool. Gets: when attempting to parse an SQL statement, oracle must first obtain a handle and load a lock on the handle. gets indicates handle request times. Pin: After handle is obtained, locate lco and pin lco so that it is not flushed out when executed. Since we understand
