From: http://www.diybl.com/course/6_system/linux/Linuxjs/20090515/167024.html A Unix system sends a system call to the kernel to implement most interfaces between user-mode processes and hardware devices. System calls are services provided by 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 SWI soft

The SWI module manages software interruption services. These interrupt service programs are closely related to Hwi hardware interrupt service programs. Generally, most of the daily processing functions are placed in these software interrupt service programs for management and operation. I. Overview of the SWI Module In the DSP/BIOS kernel, the threads managed and run by the system are divided into four leve

For hardware users, the interruption mode is defined by the user.1.

Last month saw Prolog this language, its special grammar attracted me, but after a period of study, I found that it is not as magical as the legend on the Internet, but I am still interested in it, there are predecessors said Prolog itself is not strong, But used as a supplementary language to solve some special problems or very effective, it happens that I am a C #, I looked up how to combine Prolog and C #, but I Baidu came out of the information can only be used to describe the sparse. No way

The SWI exception interrupt command allows an application to call code in system mode in user mode. in the operating system, the code is called by the system, How can this process be implemented? Let's learn with questions! The SWI command contains a 24-bit immediate number (call interrupt number), which indicates the specific call function to be requested by the user, therefore, you need to read the inter

Take a look at the function call details: Example: 1 In main. c MicIrqFuncSet (timerrentint, 2, (unsigned int) IRQ_Timer1 ); The micIrqFuncSet function calls the function in viccontrol. h. 2 In viccontrol. h _ Inline unsigned int micIrqFuncSet (unsigned int uiChannel,Unsigned int uiType,Unsigned int uiFuncAddr){Return swiHandle (0x100, uiChannel, uiType, uiFuncAddr );} The inline function is used here, that is, the swiHandle function is actually called. _ Sw
