Determine the vector I (0£i£255) associated with the interrupt or exception.2. The IDTR register reads item I from the IDT table (in the following description, we assume that the IDT table entry contains an interrupt gate or a trap gate).3.

Make sure that the interruption is initiated by the authorized (interrupted) source. First, compare the current privileged CPL (the lower two digits of the CS register) with the descriptor privileged level of the segment descriptor (that is, DPL, stored in gdt). If CPL
Control Unit performs the following operations:
1. Determine the vector I (0 ≤ I ≤ 255) associated with the interrupt or exception ).2. Read the I entry in the IDT table directed by the idtr register (in the following analysis, we assume that the IDT table item contains an interrupt door or a trap door ).3. Obtain the base address of gdt from the GDTR register and search for it in gdt to read the segment descriptor identified by the selector in the IDT table. This descriptor specifies the base
Interrupt service program.
Here, the CPU will be based on the current CS register in the CPL and GDT segment descriptor of DPL, to ensure that the interrupt service program is higher than the current program, if the interrupt is a programming exception (such as: int 80h system call), then also check the CPL and IDT table in the interrupt descriptor DPL, To ensure that the current program has permission to
Not long ago, Inprise Company (formerly Borland Company) officially announced Delphi version 5.0, its development wizards support the "Control Panel program (CPL)" framework of the generation, using it can quickly and easily develop CPL programs.

The segment descriptor is an 8-byte representation of the segment. It is stored in the Global Descriptor Table (gdt) and Local Descriptor Table (LDT). Because the segment descriptor contains a large amount of content, we will not describe them here. The key is a two-digit descriptor privilege level (DPL), which is mainly used to restrict access to this segment. It indicates the Minimum CPU priority that can access this segment.

And the GPL requires that any software that uses/modifies/derives from the GPL library must be different from the GPL agreement. LGPL allows commercial software to use the LGPL class library through the Class Library Reference (link) without the need for code for open source commercial software. This allows open source code with the LGPL protocol to b

In the bucket descriptor, the type of the attribute area consists of 0-3 bits. Bit 3 is called the e bit, E = 1, indicating that this descriptor is used to describe the code segment. Bit 2 is called a C bit. Bit c = 1 indicates that the corresponding code segment is a consistent code segment; bit c = 0 indicates that the corresponding code segment is not a consistent code segment.
