1. CPU cache The origin of cpu cache In all instruction fetch cycles of the CPU (program calculation), the memory needs to be accessed at least once (that is, what we call data on physical memory) It usually requires multiple accesses to the memory to fetch operands or save results. The speed of CPU processing […]

Linux C++ implements thread binding CPU
Foreword In embedded systems, we will use multi-core CPUs. As the performance of product chips improves, we will also have many functions and many processes running. At this time, when we perform task scheduling and tuning, we will Some processes are bound to a fixed CPU to run. Let’s share the process of CPU binding […]

A small window plug-in used to display the current system time, CPU and memory usage, and network upload and download speeds.
I’ve recently been working on a gadget that aims to generate a widget that displays the current system time, CPU and memory usage, and network upload and download speeds. Initial goals: Generate a pop-up window and keep the window on top You can make settings in the pop-up window, check the corresponding information you want […]
