C ++ code optimization Summary I. Before OptimizationBefore optimization, we should first find the bottleneck of our code (bottleneck. However, when you do this, do not deduce from a debug-version because the debug-version contains a lot of

With its advantages in large capacity and low price, NAND Flash has quickly become a new favorite of embedded system storage. Therefore, its file system research has become increasingly widespread. This article briefly introduces the commonly used

Let's start by pressing the computer power key. (1) first, the motherboard BIOS power-on self-check. According to the textbook "Microcomputer principles", the CS register is set to 0 xFFFF, and other registers are cleared. Therefore, the CPU starts

Create a yaffs2 File System on NAND Flash (1) ByOn2006-07-22 After more than half a month of hard work, we finally completed nandflash's MTD driver and the upper-layer yaffs2 file system. In the past half a month or so, we have to fight against

1> what is a hard disk parameter table? The position of the interrupt vector in the interrupt vector table set by BIOS in PC (4*0x41 = 0x0000: 0x0104) is not the address of the interrupted program, but the basic parameter table of the first hard

Previously, windows to Linux were migrated using the normal exp and IMP methods. Logical backup is used to migrate data across physical structures and operating systems. SuchI believe many of my friends are doing this. Today, we have a 50 GB
