The entry for the program is main, which calls the assembly function in main.The first thing to do is to solve the problem of defining functionsIn the C language, to extern a function declaration, and then this function in the assembly is implemented.In the Assembly, use export to introduce the function name defined in the C language, and then start writing the segment where the function name begins.An example is a function that adds six numbers.C Language: #include extern int sum (int a,int

In which we can see the C language function source code, in the end corresponds to those assembly code.
The following is a two-function assembly code,
One is Clock_init,
The other is in the same C-source file as Clock_init, and another function Copycode2ram:

As the mobile market becomes more competitive and ARPU declines, it urges equipment providers and telecom operators to provide and build next-generation mobile core networks that are more cost-effective, powerful, and convenient for future evolution. This next-generation mobile core network should achieve cost optimization, taking both CAPEX and OPEX into account. It is conducive to rapid business introduction, including network architecture and equipment transformation. It meets the requirement
