C++ Multithreading Basics

by
C++ Multithreading Basics

Basic Concepts of Multithreading In C++, multithreading allows us to split a program into multiple threads that can run simultaneously. Each thread has its own execution path, and they can share resources of the process, such as memory space, file descriptors, etc. This is different from Python’s multithreading, where due to the Global Interpreter Lock … Read more

Mutex Priority Inheritance in Real-Time Systems

by
Mutex Priority Inheritance in Real-Time Systems

1. Introduction The core objective of real-time systems is to ensure that tasks are completed at the correct times and within specified time limits. In the design of real-time systems, not only is functional correctness required, but when to start and when to finish are also important considerations. To achieve this goal, compared to general … Read more

How to Communicate Between Threads in C Language

by
How to Communicate Between Threads in C Language

First, there is no communication issue between threads within the same process. You can access data however you want; thus, we actually need to do something to actively “isolate” different threads to avoid dirty reads and writes. Second, multi-threaded programming (as well as multi-process programming) requires a foundation in operating systems. Without understanding the operating … Read more
