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 of the entire chip and runs a real-time embedd

Based on the basic functions of Layout View and viewgroup, Android provides an advanced and powerful customization mode for creating its own UI. First, the platform contains various preset view and viewgroup subclasses-widgets and layout. You can use them to construct your own UI. Some widgets that can be used include button, textview, edittext, listview, checkbox, radiobutton, gallery, spinner, autocompletetextview, imageswitcher, and textswitcher. T

Author: Anders James I have written an article "abstract-based hierarchy". Here I add an article "system architecture based on business module components".Some content has been mentioned in "project notes: Dao, web, module boundary and model classification" and "Module Interface Design". I will summarize it here. A system of a certain scale usually breaks down the system to reduce the difficulty of analysi
