Lab 1 part 1:pc BootstrapWe continue ~Physical address space for PCIn this section we will delve into how the PC starts. First, let's look at how the physical address space of a PC is usually laid out:This diagram shows only a portion of the memory space.　　The first generation of PC processors is a 16-bit word-length Intel 8088 processor that can access only 1MB of address space, or 0X00000000~0X000FFFFF. However, this 1MB is not available to users, o

Your understanding is not necessarily correct. It is for reference only. Do not copy it! The same is the same. Lab 1 [Experiment Name]: concurrent program design (experiment 1) [Objective]: to learn how to create a process in a program, observe and understand the phenomenon of concurrent execution of multiple programs. [Experiment principle]: fork (): Creates a sub-process. The child process obtains a copy of the address space of the parent process. R

Original image effect, early shooting quality is good, thanks to the source material. Figure 1 I believe there are other ways to achieve the same effect using the Lab channel processing effect diagram. But by contrast, lag channel has the most powerful color latitude, in the deployment of color has a greater advantage, this method is quick and easy, the entire process is only three minutes. Figure 2

In lab mode, it is the quickest way to turn a character's complexion red, and you need only one application image. The complexion is rosy and then the whole is bright, the background part is slightly soft and touches the handle can. Original Final effect 1, the original image is relatively dark so we first adjust its bright contrast, preliminary we use camera raw processing, the process of paying special attention to the tra

This tutorial mainly uses Photoshop in lab mode to pull the couple photos to mellow skin effect, lab mode in the production of vivid pictures is very fast, can be replaced by the channel to reduce the noise in the picture, and then increase the color saturation, the color of bright, later fine-tuning the color, add a little complementary. Final effect Original 1, open the material

Technical Solution Based on the requirements of the school's computer lab center and the performance comparison with well-known network equipment manufacturers at home and abroad, in line with the principles of reliability, stability, advancement, adaptability, openness, security and scalability, after many selections and demonstrations, the school finally adopted the products of the US network component company. The network solution topolo

It is hard work and hard work behind every development, and so is IE. To provide accurate, reliable, and sufficient data during IE development, Microsoft has created an IE performance lab. In the IE lab, Microsoft performs at least 200 performance tests on IE every day to collect data for over 57 million measurements and GB of running hours, to ensure that every small change in IE can improve the performanc

DNS master, slave, transfer, subdomain, and delegate lab manuals: before doing the experiment, you must first understand the following concepts 1. what is DNS? DNS stands for the Domain Name System (DomainNameSystem). Simply put, it resolves a domain name into an IP address. 2. what types of DNS are there? Primary Domain Name Server n DNS master, slave, transfer, subdomain and assignment Lab Manual Cutting

Csapp Buffer Lab provides an in-depth understanding of the buffer overflow experiment of the computer System (second edition of the original book), which requires the use of buffer overflow principles to solve 5 difficulty increments, namely smoke (level 0), fizz (Level 1), Bang (level 2), Boom (Level 3), KaBOOM (level 4). Deepen the understanding of function calls and buffer overflow mechanisms in practice (for IA-32 architectures).This record uses t

Introduce photoshop in Lab color space to make psychedelic color lotus, mainly in lab mode down to complete, the method is very simple, like the students can come together to learn! First look at the effect of the comparison chart: Pre-processing preparation Use "curve" to depress brightness first, easy to create atmosphere Then "image-> mode->

Lab brightness channel sharpening is one of the most commonly used sharpening methods for professional photographers. it can avoid the color halts and colors generated during sharpening and make the sharpening look more natural, it also makes it possible for us to sharpen an image multiple times. This sharpening technique comes from Scott Kelby's Photoshop CS3 digital photo professional processing techniques book
