good architecture software

Architecture of object-oriented software requirements Here, we need a specific way of thinking and a unique methodology. It is necessary to correctly understand and properly use the classical demand analysis theory.1. establish a system's overall framework as soon as possible in terms of ideological methods, and generally locate the positions of various specific targets in the system framework and their rol

name. After successful matching, the offset of the file in SD is obtained. The 9-bit offset (512 bytes, one sector) is the position of the file. Fopen returns a handle that corresponds to a data structure. The structure generally includes the start position, length, and current read pointer position of the file. The record start position and length are used to prevent cross-border reading. 6. fread The read operation is performed based on the current read pointer of the handle, and the cu

class, where each terminator in the expression produces a Varexpression object in the stack.Nonterminalexpression Non-Terminator expressionEach rule in the grammar corresponds to a non-terminating expression, and our example is that the addition and subtraction rules correspond to the two classes of addexpression and subexpression respectively. The non-terminator expression increases according to the complexity of the logic, in principle each grammar rule corresponds to a non-terminator express

pointer array fops is registered in the system's API management array.6. The system is classified management of the drive, it has a record of each driver interface function pointer array Base address array, each driver in advance in order to contract, such as the first element of the group is the key driver Key_fops, and the second is the LCD driver lcd_fops, and so on. When a driver is loaded, the driver logs the corresponding FoPs through the API-managed interface to the corresponding locatio

Inversion of control inversion controls: The applied process is not controlled by the application, but is controlled by the framework. Default Behavior: The framework defines a series of default behaviors. Extensibility Extensibility: Apps can extend the functionality of the framework, or you can modify the default behavior of the framework. The Non-modifiable Framework code framework itself cannot be changed: When the framework is expanded, its own code does not need to be changed.

Module Division Module Partition "Zoned" is the meaning of planning, meaning how reasonable to divide a large software into a series of functional independent part of the cooperation to complete the system needs. C language as a structured programming language, in the division of modules mainly based on functions (according to the function of the division in the object-oriented design to become a mistake, Newton's law encountered relativity), C-langu
