System calling is a service provided by the operating system of the operating system. User Programs reference various services provided by the kernel through various system calls. The execution of system calls puts user programs into the kernel, this is completed by the SWI Soft Interrupt. The Soft Interrupt definitions for Linux kernel system calls corresponding to the at91rm9200 processor are as follows: # If defined (_ thumb _) // thumb Mode# DEFINE _ syscall (name )/"Push {

Volatile is intended to have two types of statements: 1. "transient" and 2. "changeable ". Both of them are feasible. But what does volatile mean? An example is given (taking Keil-C and A51 as examples ). The example is from Keil fqa). After reading the example, you should understand the meaning of volatile. If you still don't understand it, you have Read it again. Example 1. Void main (void){Volatile int I;Int J; I = 1; // 1 not optimized I = 1I = 2; // 2 is not optimized I = 1I = 3; // 3 not
