The library is essentially a binary format of executable code that can be loaded into memory for execution. The database is divided into static and dynamic databases.Differences between static and dynamic Databases

Simulation in Modelsim requires the addition of a simulation library provided by Quartus, due to the following three areas:· Quartus does not support testbench;• Called Altera functions such as megafunction or the LPM library;• Timing simulation is done under Modelsim.The following is an example of Altera devices, how to add Altera's simulation library in Modelsi
Function libraries can be divided into static libraries and dynamic libraries. Create a Linux static library and a Linux dynamic library and use them here. The static library will be connected to the target code during program compilation. This static library is no longer needed when the program is running. The dynamic
In the past, when customizing the wince Chinese system, the NK was always too large and the system failed to be customized. I encountered this problem again today, so I cannot avoid it all the time. Let's try again. The result is the same as we thought. It's still because NK is too big and depressing. You must find the root cause, I tried again twice. Wow, it's successful! Happy! Summary:

What is a database?
Libraries are existing, mature, and reusable code.In reality, every program depends on many underlying libraries. It is impossible for everyone to start from scratch. Therefore, the existence of libraries is of extraordinary significance.

The final executable code of the C source program must be preprocessed, assembled, compiled, linked, and linked to the compiled target code (. o file) and other target code (such as a few target files linked to an executable program) and library files linked to form an executable program.
Generally, the first line of code for writing a C program is # include

In this case, we often use the command gcc-O helloworld. C during compilation to g
Linux static library and dynamic library
A large number of libraries exist on windows and linux platforms. Essentially, a library is an executable binary code (but cannot be executed independently) that can be loaded into memory and executed by the operating system.
There are two types of libraries in Linux: static library

The explanation of the static link library is not the focus of this article, but before explaining the DLL, the example of a static link library can help us quickly build the concept of "library.

Static libraries, dynamic libraries in UNIX terms, or archive files (archive often end with. A) and shared objects (share object often starts with lib. So end) more accurately. A static library, a dynamic library may be a term under windows, but the concept is the same. The following unified said static library and dynamic library.Static

Dynamic Link Library ConceptsDynamic Library (Abbr,dll) technology is a technique commonly used in programming. Its purpose is to reduce the size of the program, save space, improve efficiency, with high flexibility. Using dynamic library technology makes it easier to upgrade software versions. Unlike a static library,
First, let's take a look at the knowledge about static databases:
Program compilation usually requires preprocessing, compilation, compilation, and linking. For some public code in our project, if you want to reuse it, You can compile the code into a static library file. In the link step, the linker obtains the corresponding code from the library file and generates an executable file. The execution file of
