6.3.1 The main process of generating assembly code from intermediate directivesIn this section, we can focus on "how to translate an intermediate code into assembly code". The intermediate code for the UCC compiler is a four-tuple, including operators and 3 operands, as shown below.Of course, some intermediate code only need to use opcode and DST, for example, the unconditional jump instruction "goto BB2;" There is no need for SRC1 and SRC2. To facili

Dir specifies the direction of data transmission. These words include SRC, DST, SRC or DST, Src and DST.
Example:
DST net 128.3; this is a relatively complex primitive with the structure of Dir type number, indicating the condition for the target network to be 128.3.

Analysis:When the original image is a horizontal screen or vertical screen, it is hoped that the thumbnail will maintain the original scale, do not change the integrity of the original, that is, equal to zoom!At this point only need to determine the original image width and height, and the maximum width of the target graph, compare the width and height ratio of the target graph and the original width and height ratio of the size, in order to determine the original image is a horizontal screen or
The debug environment of the assembly is generally relatively small, and there are very few very good compilers. The easy assembly of the Reallychenchi Design is a compilation compiler that works well for beginners. Easy assembly is an assembly language integrated development environment, mainly for assembly language beginners, can also use it for development. In addition to ordinary editing functions, it can also automatically organize formatting, highlighting and compiling, linking, debuggin

Approximate Gradient
For example, when the kernel is 3.
First, calculate the approximate derivative of x:
Then, calculate the approximate derivative of the y direction:
Then calculate the gradient:
You can also write it as follows:
Function implementation
The Code is as follows:
Var Sobel = function (_ src, _ xorder, _ yorder, _ size, _ borderType, _ dst ){(_ Src (_ xorder ^ _ yorder) | error (arguments. callee, IS_UNDEFINED

Parameter Function: Copy all content of Disk 1 to Disk 2. You do not need to ask, and then exit Ghost.
2. Back up all the content on the disk to an image file.
Graphic Interface: Disk To Image
Example: ghost-clone, mode = dump, src = 1, dst = d: \ Win98sys. gho-z3-sure-fx
Parameter Function: Back up all the content on the first hard disk of the machine to the d: \ Win98sys.

Preface I have been home for 3rd days, and my status has not been very good. I want to fill in my teeth and check my health. seeing my friends, I am worried about school moves. It is rare that I can spare time to think about it, here, we also read The key to recursion is to define a function first. Do not try to implement it in a hurry, but clarify its functions.For the tower of Hanoi Problem, we define the following function prototype:
void hanoi(char src, char mid, char
Ghost-clone, mode = {copy │ load │ dump}, src = {drive │ file │ drive: partition}, DST = {dri-ve │ file │ drive: partition}/fro/FX/Rb/f32/Z (N)/sure {Other parameters}
The meanings and usage of the main parameters are as follows:
-Clone.
Mode =: This option is used to set the usage mode of ghost.exe. There are six modes available: Copy, pcopy, load, pload, dump, and pdump. Among them, copy, load, dump refers to the operation of the hard disk to the ha

Dir specifies the direction of data transmission. these words include src, dst, src or dst, src and dst.

Brief introductionThe Shutil module provides advanced operations for a large number of files. Specifically for file copying and deletion, the main functions are directory and file operations, as well as compression operations. The operation of a single file can also be found in the OS module.Note Even a higher-level file copy function (Shutil.copy (), shutil.copy2 ()) cannot copy all of the file's metadata. This means that the owner and group of the file and the access control list are lost on t
