What is GIL GIL (Global Interpreter Lock) is a global lock in the CPython interpreter: At any given time, only one thread can execute Python bytecode; Even if you have many threads in the same process, only one thread can actually run Python code (the others are waiting for the lock). It is important to … Read more
Introduction What is a Thread 1) A thread is the smallest unit of scheduling in an operating system. 2) A thread is the actual executor of a process, consisting of a set of instructions (the owner of process resources). 3) Multiple threads within the same process share the same memory space, allowing for direct data … Read more
Limitations of GIL (Global Interpreter Lock) The GIL in Python is a mechanism in the CPython interpreter that ensures only one thread executes Python bytecode at a time. This is a bottleneck for CPU-bound pure Python programs, as true parallel execution cannot be achieved even with multiple CPU cores. Advantages of Multiprocessing Using multiprocessing can … Read more
Concurrency refers to the ability of a program to handle multiple tasks simultaneously. In Python, the two core methods for achieving concurrency are multithreading and multiprocessing. Although both can execute tasks “in parallel”, their underlying implementations and applicable scenarios are quite different, with the key difference being the memory space isolation between processes and threads.Multithreading … Read more

A common understanding in the automotive industry is that future automotive software will dominate industry competition, hardware will tend to unify, and software will become an important aspect for automakers to build differentiated products, which is known as “software-defined vehicles”. Currently, “software-defined vehicles” have become an unavoidable focal point for automotive manufacturers. In 2016, Tesla … Read more
Quoted from < Design Patterns for Embedded Systems in C > Agile Process in Software Development Introduction Traditional embedded software development often faces numerous challenges, such as frequent changes in customer requirements, long development cycles, difficulties in hardware-software integration, and complex testing and validation. The traditional waterfall development model proves inadequate in addressing these challenges. … Read more
