Preface: Robert C. martin summarizes the principles that should be followed in Object-Oriented Design (OOD). These principles are called "prinles les of OOD ", for more information about principles of OOD, see object menter. This article introduces the interface separation principle in "Principles of OOD": interface segregation principle (ISP ). You can view the original interface segregation principle (ISP

Generally, based on the different chips of various companies, it generally includes in-chip Flash Boot Mode, In-chip RAM boot mode, and external memory boot. Mode. In addition, many of the 7.7 chips now support in-chip Boot programs in System Programming (

The ISP is an abbreviation for Image Signal processor, the full name is the image processor. In the whole process of camera imaging, it is responsible for receiving the raw signal data of the photosensitive element (sensor), which can be understood as the first step process of photographing and recording the whole camera, which plays an important role in image quality.High-pass 8974 photo display process to clearly see the location of the

ISP -- Interface Segregation Principle, segregation 1. ISP Overview (ISP -- Interface Segregation Principle ): It is better to use multiple dedicated interfaces than to use a single total interface. The dependence of a class on another class should be based on the smallest interface. An interface represents a role and should not assign different roles to an inter

1. Basic Introduction The basic principle and design of the upstream module of Nginx can be referenced by clicking on the Open link. In fact it is a special handler module, the SET function of various xx_proxy instructions, will set the Content_handler of the location, such as Xx_memcached_module ngx_http_memcached_ Handler (), Xx_proxy_module Ngx_http_proxy_handler (). You can simply read the code and find that they are almost 1. First create a
