Not all users can imagine how a computer system of any rank works. But everyone knows for sure that the central processor plays a paramount role in ensuring the calculations and the overall health of the system. At the same time, few people realize what constitutes a set of commands that specify the sequence of actions of the processor. How it all works in practice will now be considered.
The set of commands that specify the sequence of actions of the processor: what is it in the general understanding?
As you know, the central processor (CPU or CPU) plays a paramount role in the computer system, since all processes associated with the functioning of the operating system and installed applications are assigned to it.
The operating system itself, and any one, is built on the implementation of applets and applications. We can say that the set of commands that specify the sequence of actions of the processor is a program that executes the direction of a certain action in the calculations when the executable process starts. What program is this is another matter. The essence of this process is that the processor is given some indication of the performance of a particular function.
Microprocessor Commands: How Does It Work?
If you still do not know how this works, it should be noted that at the start of the same executable file of the program (usually an EXE-type), the application stored on the hard drive is accepted for execution.
Typically, a command executed by a processor is addressed directly to its memory location or to a memory, and after binary code processing, it is executed. As already clear, the processor can not accept commands like "Run." For this, a so-called compilation is provided for any programming language, that is, the conversion of the commands of the language itself into machine-accessible code.
It should be noted that the totality of commands that specify the sequence of actions of the RAM or processor obeys the strict programming rule - True / False (True / False). A third is not given, although in the branching of algorithms, the general principles for organizing the operation of a computer imply the introduction and use of the Else operator. The general principles of computer organization are built on just that.
In other words, the scheme is presented as “Yes-No-Otherwise”. If the processor does not agree with the first statement, refuses to perform, following the second principle, an action is selected from those specified in the programmable files with the conditions specified in the third paragraph (we are not talking about them at all). And the accompanying components can be quite a lot.
Executable files and dynamic libraries
Speaking of what constitutes a set of commands that specify the sequence of actions of RAM or processor, it is impossible to ignore the execution of commands based on executable and additionally loaded objects.
Some programs presented in the form of executable files such as EXE, COM, BAT, BIN, CMD, and many others work by sending their own process execution commands directly to the CPU.
Other program files that require loading additional interfaces or settings can additionally load the so-called dynamic-link DLLs and settings files such as CFG or XML into RAM.
In this case, the executable program loads into RAM a special file in which the compiled type executable code (for example, the DLL format) is written, without which it simply cannot work.
Using dll files without exe
However, microprocessor instructions can be processed without executable files. Just look at the installation processes of VST-plugins in the most popular DAW-studios (Digital Audio Workstation).
In this case, we are talking about the fact that you can simply copy the DLL file to the desired location, set the search, and the program itself will determine the new synthesizer or effect.
Failures and errors: how to deal with them?
The main components of the computer in the form of a processor, RAM and hard drive do not cause misunderstanding. At least I really want to believe in it.
But sometimes the problem of the system’s operability may consist in the fact that the set of commands that specify the sequence of actions of the processor does not reach the CPU due to a malfunction of the OS installed on the computer. This is due to the fact that the service being executed at a certain moment is trying to execute some code, but the system does not perceive it (microprocessor commands do not work).
It is believed that the simplest solution to the problem could be to start a command line with administrator rights (cmd in the Run console or run from the System32 folder), in which the combination sfc / scannow is written. This command allows you to identify damaged or missing components in the system (moreover, with regard to dynamic libraries in the first place).
The second option, if the microprocessor instructions are not processed properly, is to use the overwrite commands of the boot sector:
- Bootrec.exe / fixmbr.
- Bootrec.exe / fixboot.
- Bootrec.exe / RebuildBcd.
Note that these commands work both in the current system (it is better to use Safe Mode when using them), and in the standard configuration when loading the recovery tool from external media like a CD-ROM or flash drive. In this case, the set of commands that specify the sequence of actions of the processor, restores and overwrites the bootloader. By the way, these commands can be adopted, since they are the ones that work best when restoring the system.
In extreme cases, you can use the specially developed DLL Suite utility, which detects missing Windows system libraries, and after scanning installs them yourself. By and large, user participation is reduced only to following the instructions of the "Wizard". True, you can not do without an Internet connection, since the download will be made from there, and not from your own distribution.
conclusions
So, let's try to summarize everything. We can say that the set of commands that specify the sequence of actions of the processor is a regular program written in a certain language and compiled into code recognized by the machine. The issues of the programs themselves are another matter. As it is already clear, at execution they can address both directly to the processor, bypassing random access memory, and involve additional components. But this also affects the performance of the central processor. Not only is the loading of modules with executable codes carried out in the RAM, which is processed by the CPU, the processor itself is also loaded. But you can’t get anywhere from this, since all modern software is built on these principles.
