The MOV instruction is a dual-operand instruction and cannot be fully memory-operated in two operandsFormat: MOV dst,srcPerform action: DST Note:1. The destination number can be a universal register, a memory unit, and a segment register (but not a CS segment register).2. Immediate number cannot send segment register directly3. Does not allow data to be transmitted directly to two storage units4. No direct transfer of information between two segment registers is allowedAssembly Language Learning
Chrony software instructions for use, chrony instructions for use1.1.1 chrony Introduction
Chrony is an open-source free software that can keep the system clock synchronized with the clock server (NTP) and keep the time accurate.
It consists of two programs: chronyd and chronyc.
Chronyd is a daemon running in the background. It is used to adjust the system clock running in the kernel and synchronize the clo
Powerful linux IDE-Geany configuration instructions, linuxgeany configuration instructions
I started using Ubuntu today (mainly to prevent myself from playing games on windows) at the beginning, I was not used to finding a suitable Compiler (when can DEV c ++ come out of Linux?). codelite code :: blocks won't be configured. I don't know much about the tutorials on the Internet, so I started to study Geany.

Default Configuration:1> allow anonymous users and local users to log on.Anonymous_enable = YESLocal_enable = YES2> the logon name used by anonymous users is ftp or anonymous, and the password is blank. anonymous Users cannot leave the anonymous user's home directory/var/ftp, and can only download but cannot upload.3> the login name of
the memory and locate the production date as 01/01/92.
(2) run the e command to modify the date and run the D command to check whether the modification failed.
4. Fill in data to the unit in which the memory starts from b8100h.
Change the entered data and address, and find that a pattern is controlled by two memory units. The former controls the style and the latter controls the color.

Experimental conclusionLab missions (1)1. Write instructions to memory using the e commandFirst use the e command to the memory unit starting from 1000:0 to write the task requirements of the machine code, and then use the R command to see the register status in the CPU, you can see, CS=073FH, ip=0100h, point to memory 073f:0100, and then use the R command to modify CS, IP content, so that CS : IP points to 1000:0. Then use the T command to execute th

I. Tutorial Purpose1. understand how to use the debug tool to compile and debug assembly commands.
2. master the basic knowledge about CPU, registers, and memory in Chapter 2.
3. Master the usage of several comma
Debug Command supplement
In executiondThe command can contain the address parameter (segment address: Offset address), where the segment address is first sentdsRegister and then hand it over to the processor.
Therefore,dThe command can also be used as follows:d SR:offset(SR refers to segment register)For example:
-R ds: 1000-d DS: 0; view the content in the memory range starting from 1000:0
-R ds: 1000-d DS: 10 18; view 1000:10 ~ Contents in
-D Cs: 0; view the instruction code in the current Cod

SSDB basic instructions and usage, SSDB basic instructions
There are several reasons for using SSDB at that time. First, when designing the contest module, You need to query the Rank of the current competition multiple times because you click to query the Rank of the current competition, the amount of data queried each time is large. to efficiently obtain data, the SSDB database is used. The second aspect i

MoV ax, 2000; Save the number H to the Register ax
MoV SS, ax; Save the number 2000h in the register ax to the stack segment register SS
MoV sp, 10; Save the number 10 h to the stack address register sp
The initial stack top is, and the initial stack bottom is.
2. debug each line of Assembly commands in one step. After each command is debugged in one step, run the D command to view
stack is 2000:0010, mov sp, 10, after reading the information, we found that 10 Memory Spaces are reserved for the following registers, such as CS.
As for the interrupt mechanism written in the book, that is, every time debug uses t to execute the command, it will stop executing and display the status of each memory and the next operation. The above mov SS, 10 must have been executed, however, the next stack cannot completely restore the state of the memory in the previous step, so the value of
