most used architecture software

Hardware and software are two parts of a chip system that are mutually dependent. This article summarizes the hardware and software components of a chip.(1) Hardware Master CPU: computing and control core. The basic architecture of the Baseband Chip adopts the structure of microprocessor + Digital Signal Processor (DSP). The microprocessor is the control center o

I personally think that there are too many concepts in this book. The architecture and development of software are not a combination of concepts. Just use the appropriate words to describe some empirical things. The so-called risk-driven model selects the appropriate design strength based on the project situation to avoid over-design. For complex software systems

Content: Simple law (subtraction design) Subtraction design is a strategy, and creation is a strategy to win What is EIT Software creation? Use of EIT Creation Features of EIT Creation EIT-shaped internal elements Conclusion The complexity of software design and future changes are essential and cannot be deleted (because deletion is no longer a complete and life-saving system ). The subtract

the enterprise access the webserver/application server via the Internet? b/S structure;? Users are not directly interviewed for data, data security.§ "Internal and external" model is the disadvantage of the enterprise external users to change and maintain data, slow, more complex lock. The dynamic interactivity of data is not strong§ Mixing principle Two: the principle of "the search and Change is different":– no matter where the user is located inside or outside the enterprise (local area netw

: Data and operations. In C language, struct is only a collection of data. We can use a function pointer to simulate struct as a "class" that contains data and operations ". The following C program simulates the simplest "class ": # Ifndef c_class# Define c_class struct# EndifC_class{C_class A * a_this;/* This pointer */Void (* Foo) (c_class A * a_this);/* behavior: function pointer */Int A;/* Data */Int B;}; We can use the C language to simulate three features of the forward Obje

this field, and architects will have the opportunity to re-engineer the front-end architecture, or even the development process, to make the entire software production more efficient.This article will explore the changes it brings to this field.Text: Features of enterprise application front-endEnterprise Application System is a very common software system, the c

servers are used, when one server goes down, only part of the data in the system is unavailable, not all. Therefore, database splitting can not only use multiple servers to share the load pressure on the database, but also improve the overall availability of the system. There are two ways to split data::Vertical Split and horizontal split.1.1 Vertical Split Vertical splitting refers to splitting the data tables accessed by each module into different

-slave backupAnd so on, the specific cache strategy needs you to combine the project consideration, the personal comparison recommendation Memcached, enough on the line.WCF,WCF Restful,webservice,webapi?For. NET system, these technologies are able to decouple resources and services, and which technology needs to depend on your application scenario.Personally, I prefer to use the WCF TCP pattern for enterprise intranet applications, which is highly efficient and supports duplex communication.When

perspective of the entire hierarchy, development tools and applications belong to the same level, because they all use an interface, that isOperating System Application Programming Interface (API). The application interface provider isRuntime Library, What kind of Runtime Library provides what kind of API, such as the posix api provided by the glibc library in Linux; Windows API provided by the Windows Runtime Library. The Runtime library usesSystem Call Interface(System Call Interface), system

An excellent architect always has a good balance between the merits of various solutions and the corresponding cost, which is the architect's rich experience and broad knowledge system. The message-based software construction model is the architect's necessary knowledge point, this article will describe the model's evolution process in detail. Remember the first time I was dealing with the company's software
