udemy software architecture

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

release it explicitly when exiting the critical section. 2) inflexible and inefficient. Depending on the context in which the application is running, different lock types are required for implementing the critical section. However, if the lock primitive is hard-coded to the software in every place in use, it is completely unnecessary and time-consuming to change the primitive. These modes can alleviate the above problems to simplify serialization

environment.Typical single-task program architecture (1) starting from the specified address when the CPU is reset; (2) Jump to the assembly code startup for execution; (3) Jump to the main program of the user owner and execute it in main: A. testing various hardware devices; B. initialize each software module; C. Enter an infinite loop and call the processing functions of each module. The user's main prog

There are no software development companies that do not use a three-tier architecture or higher-level architecture. For example, if your project team has three people. If a layer-3 structure is used, the job can be split into one person as the UI Layer, one person as the data access layer, and one person as the business logic layer. Everyone is responsible for

Wheat College is an online video learning website, mainly about it development related content, interested students can pay attention to. Another site I think is a good one is geek college. Of course, these are off-topic.A few days ago, just a former colleague

http://blog.csdn.net/horkychen/article/details/46612899From the point of view of architecture design (so-called composition theory), software systems are modules and interfaces.The module (Hierarchy/component) determines the division of labor, and the interface determines interaction.An API is the definition of an interface. The modules do not need to be concerned with the implementation of other modules, o

Successful software architecture design is of high quality, and the time and technical decision-making can meet specific requirements.The sending method must have the following qualities: Good modularization: Each module has clear responsibilities, loose coupling between modules, high cohesion in the module, and reasonable information hiding. Adapt to functional requirements and technical changes: in

Difficulties in designing motion control system software architecture: 1. The customer's requirements are constantly increasing according to actual needs. Due to the needs of industrial production, the demand is constantly raised, and the domestic motion control system software started late, is still in constant exploration, in more cases, the development is ba

Agility can solve the bureaucratic problem of the development model and respond to changes in users' business needs from the perspective of action; The architecture can respond to changes in business requirements from the design perspective, and even solve the collection and validation of requirements in the Demand Survey phase. Changes in requirements can generally take place in three fields: interfaces, processes and rules, organizational str

the subsequent article in-depth analysis, extraction design structure and design skills of the essence, for the vast number of software industry colleagues to share. 2. Basic knowledge of SCA specification The SCA programming model is highly extensible and language neutral, and it is easy to be extended to various implementations of language technology java,c++,bpel,php, spring, and many other remote access bindings including Web SERVICE,JMS, Ejb,j

The purpose of software architecture design is simply to break down the software system and reduce the complexity of software system development under the premise of keeping the software internal connection, and the basic methods of decomposition

Common web development software architecture 1. view requirement analysis and product PRD: Product Requirement document 2. Create a database table based on the PRD and product prototype. Pay attention to the requirements of the three paradigm, use tools to access the relational database, and quickly clear the Database concept. 3. Build a project architecture
