Introduction to the classic architecture model of the software architecture and design model Source: recommended by netizens 　　RootAccording to Linda Rising's patternAlmanac has over 70 known architecture models. This is only a lot of statistics, including many models that are generally considered as

correspond with the group tour/free line, showing the group tour/free line products.3. Set the main page of the part you want to test independently as a plate. This doesn't have to be explained too much.What are the benefits of this design? That is, no matter how the page changes, as long as the function point of this data processing is good, you can use the fas

For you illustrator software users to detailed analysis of the vector design software to share the experience of using skills. Skill Sharing: How does the font of the illustrator become curved and the path The Text tool on the toolbar is a tool group, and the left-click Text Tool does not put the tool in his group, which has a path te

Developed by filter solutionsnuhertz, nuhertz is an industry leader in filter design software.The trial version is only available for download on the Internet, and the trial period is only 20 days. After the software is used, the software is basically paralyzed. Of course, you can find the serial number if you are careful.The function is very complete. It is wort

performance is inversely proportional to the set of all waiting times for the entire system, any operation that increases the wait time faster than the load will become a problem. Despite all this, I would like to point out that if you find it difficult to meet performance and scalability goals, it's important to wonder if you've chosen the right architecture. Still, look at the big picture and make sure someone is taking the architect's responsibility.SummarizeThis article puts forward some pr

approximately constant during the demodulation process. Step 3 Update the loop intermediate variable s_pll (n ), F0 is a fixed NCO center frequency. So far, a complete SPLL computing is complete. In step 3 and Step 4 calculation, the ring filter coefficients C1 and C2 can pass the loop sampling interval T (or the loop update interval) determine the free loop frequency ω n and the damping coefficient of the loop, as shown in [2]: KD is the gain of t

Fritzing is a set of software designed for PrintedCircuitBoard printed circuit boards. It is a tool especially intended for designers, artists, researchers, and amateurs. Like Processing and Arduino, Fritzing developers design this software in the spirit of openness, simplicity, and sharing. Fritzing is a simple and easy-to-use

style, instead of other styles.3. Then, change the stroke in the font to none. On this basis, you can apply the gradient and edit the font.You can also: After the words are typed, make another gradient and define the gradient fill as a graphic style,Select the text to fill in the gradient, and then apply the graphic style just defined.Another way is to fill the gradient with the appearance of the character. The method is to add the character, click the triangle drop-down menu on the appearance

Software and Hardware Design and Implementation of DSP-based Internet Access Solution [Date:] Source: Electronic Technology Application by fan Qing Han Chong Zhao Wei Hua [Font:Large Medium Small] 　 With the development of modern network technology, embedded systems, such as single-chip microcomputer and DSP, require more and more access networks, for example, an electric meter system w

, It should be better designed in advance, and you do not need to do too much, but there must be. Better than none. Projects generally involve a larger flow of people, because the long-term return is low. In addition, because of the low individual output, the staff's salary and level will be lower. Therefore, we should have a backbone staff to help you confirm the needs and design of the entire project, rather than making everyone feel

Install the Open Source PCB printed circuit board design software Fritzing in Ubuntu Fritzing is a set of software for designing Printed Circuit boards (Printed Circuit Board), especially for designers, artists, researchers and amateur players. Like Processing and Arduino, Fritzing developers design this

Those prototype images that are refined and easy to use are always very attractive to me. However, so far I have not drawn a decent prototype. After I tried Visio and axure, I felt unsatisfied with ease of use. Prototype DesignAs the basis for communication between members of the product team, the diagram should clearly express the intent of the designer. For this purpose, the prototype map produced by a pen and a piece of paper is more original. However, due to the inconvenience of retaining an

Machine State Migration Table". Handle events and transfer status.Such a way is not flexible. Because each state is added, add a heap of If. else's decision.2. Switch...case ..... There is no switch syntax in Python, can be replaced with dict, here I use the General C language to describe the narrative. The following code can be directly compiled execution, in Dispather, nested 2 layer switch. Similar to the above if: Else's structure, just replaced by switch. #include 3. function pointer metho
