traps general protection

Absrtact: In order to improve the efficiency of CPU utilization, we use interrupt policy to deal with some external events. At the same time, the software also needs to trigger some interrupts and exceptions, such as 0 interrupt/page fault exception.

Intel 80x86 CPU Hardware interrupt process in protected mode University learning operating system principle, feel process and file seems to be introduced up to two pieces of content, but slowly found that to understand the operating system work

If you are unlucky enough to have a good understanding of the WIN32 application environment, your software will eventually be arbitrarily ravaged by the fierce debugger. But you are far from being defeated, if the anti-debugging technology

3C Certification Of all the power supply, only one power supply has not passed the 3C certification, of course, you can not buy in the market, because the power supply in our market, must pass the 3C certification, the power is not certified the

Eight articles on the protection model have come to an end today. : D: Back to the truth.Today, let's take a look at the theoretical part.1. Exception Source:1) The processor detects an exception in a program error.A program error is detected during

We always think that understanding interrupt is the beginning of understanding the kernel. Interruptions have far exceeded the scope of peripheral services, and are an important part of the modern architecture. 1. Basic Input and Output Modes There

Eighth. Abnormal control FlowStarting from power-up to the processor, the program counter assumes a sequence of values of A0,A1,... A (n-1), where each a (k) is the address of a corresponding instruction I (k), and each transition from a (k) to a (k+

Currently, all kinds of illegal attacks on the Internet are hard to prevent. To stay away from malicious attacks, we must reinforce the network layer by layer to effectively improve the network security protection capability. Defends against hacker
