Author: Wushan Old Demon Background Writing Android asynchronous tasks in business has always been a challenge. The previous callback and thread management methods were complex and cumbersome, making the code difficult to maintain and read. JavaScript actually faces the same problem in the front-end field, and Promise is one of its more mainstream solutions. Before […]

Table of Contents 1. Introduction to Ajax 1. The concept of asynchronous and synchronized 2. Why is it said that synchronous requests will “reload the entire page”, while asynchronous requests “will only load part of the page”. What does this mean? 3. Functions and advantages of Ajax Function Advantage 4.Why is Ajax called asynchronous javascript […]
Asynchronous FIFO design simulation based on Verilog HDL
1. What is asynchronous FIFO Asynchronous FIFO is one of the FIFO designs (First In First Out, data written first is read out first). Since read and write operations are independent, asynchronous FIFO is often used to transmit multi-bit data across clock domains. Asynchronous FIFO will be referred to as FIFO in the following. Under […]
C++ uses thread pool to simulate asynchronous event processing mechanism
There are asynchronous event processing mechanisms in many C++ frameworks, which makes us often confused and difficult to understand when looking at the source code. The programming routines contained in it may be some mature technologies that we are not familiar with, such as WebRTC. It is similar to Qt’s signal and slot mechanism, thread […]
CompletableFutureBatch asynchronous task processing
When we encounter many businesses being processed at the same time in the project, if it is serial, it will definitely affect the performance. At this time, asynchronous execution is needed. When it comes to asynchronous execution, there must be many solutions. Option 1: For example, using spring’s asynchronous annotations, such as the following code, […]
Asynchronous notifications, the cornerstone of the driver
Asynchronous notification process The key points start from ②: ② APP registers the signal processing function func for the SIGIO signal. Later, the APP receives SIGIO When a signal is generated, this function will be automatically called; ③ Tell the driver the PID (process ID) of the APP. This call does not involve the driver. […]
Refactor Android asynchronous code using promises
Background Writing Android asynchronous tasks in business has always been a challenge. The previous callback and thread management methods were complex and cumbersome, making the code difficult to maintain and read. JavaScript actually faces the same problem in the front-end field, and Promise is one of its more mainstream solutions. Before trying to use Promise, […]

Android: OkHttp synchronous request and asynchronous request
1. Foreword In my previous work on network requests, I used post requests. After learning about them, I found that there are many types of requests. The following focuses on the synchronous requests and asynchronous requests of get and post. 2. Specific content 1. Characteristics of Okhttp: Supports HTTP/2 and allows all requests to the […]
