1. Introduction to PLI functions Verilog PLI(Programming Language Interface) is a mechanism for Verilog code to call C/C++ functions. It enables Verilog to call C/C++ functions written by users like some system calls (e.g. $display/$stop/$random), so that we can start our own system task/function with C/C++ language to realize the inconvenient ...

In modular programming, high cohesion and low coupling are usually the criteria we need to achieve, which is believed to be a problem for producers and consumers. In the study of threads, I have seen this example, so I will learn it here. The problem of producer and consumer is a classical thread synchronization problem. In real life, ...

Multithread Communication - Producer-Consumer Model Producer-consumer pattern is not one of the 23 design patterns proposed by GOF. All the 23 design patterns are based on object-oriented, but there are many efficient programming patterns in process-oriented programming. Producer-consumer pattern is one of them. It is the most commonly used d ...

AOP (Aspect Orient Programming), Aspect Orient Programming, is a supplement to OOP. Object-oriented programming considers the structure of the program from a static point of view, and aspect-oriented programming considers the running process of the program from a dynamic point of view. AOP bottom layer is realized by dynamic proxy mode. There ...

Cellular Automata-Urban Planning 1. Urban Scale Design Xiongan New Area covers an area of about 2,000 square kilometers. It covers Xiongxian, Rongcheng and Anxin counties in Hebei Province and some surrounding areas. It is located in the hinterland of Beijing, Tianjin and Baoding. The area is searched and extrac ...

Because in previous work, single thread can solve the problem, and multi-threading is seldom used, even when used, it is encapsulated in some framework source code, so it has not been too concerned about this problem. But two days ago, I came across a question about synchronization between multi-threads, so I took this opportunity to look at ...

Today, I am immersed in IOC's pursuit of design patterns. I have listened to many lectures and seen many examples. This is a test project of mine. In order to test the code, I first prepared two classes: Car and ICar. These two classes are similar to DAL and IDAL in our usual project. Now let's start! 1. First add a class InitAutofac to our p ...

The decorator and the decorated have a common superclass. The purpose of inheritance is to inherit the type, not the behavior. Decoration mode is to dynamically extend the function of an object without changing the original file and using inheritance. It wraps real objects by creating a wrapping object, that is, decoration. In fact, Java' ...

Swing is an indispensable window tool group in Java and a powerful tool for users to build graphical user interface (GUI) programs. Java Swing components automatically generate events to respond to user behavior. When a user clicks a button or selects a menu item, the Swing component generates an Action Event. Swing components generate many eve ...

IO flow Concept: IO stream is used to process data transmission between devices Java operates on data through streaming Java classes for operation flow are in the IO package Flow is divided into two kinds according to flow direction: input flow and output flow. Flow can be divided into two types according to the type of flow operation: B ...
