An interrupt vector table (IVT) is a data structure that associates a list of interrupt handlers with a list of interrupt requests in a table of interrupt vectors. Each entry of the interrupt vector table, called an interrupt vector, is the address of an interrupt handler (also known as ISR ).

Image Vector Table (IVT)：这是BootROM从启动设备读取的第一个镜像。 IVT包含了启动过程中BootROM使用的必要数据，如各个镜像的入口点、指向设备配置数据（DCD）的指针和其他指针。 Device Configuration Data (DCD)：提供了对设备进行配置的数据。 Self-Test DCD：用于执行自测。 Application boot image：用于启动应用程序的镜像（BootLoader），通常芯片使用方会自行开发这个镜像，可以把它类比为linux中的uboot。 Serial boot image：包含通过串行接口启 …

In this tutorial, we will talk about the interrupt vector table. Firstly, we will define the interrupt vector table (IVT). Secondly, we will see the role of IVT for interrupts and exceptions processing in microcontrollers or microprocessors.

On the x86 architecture, the Interrupt Vector Table (IVT) is a table that specifies the addresses of all the 256 interrupt handlers used in real mode. The IVT is typically located at 0000:0000H, and is 400H bytes in size (4 bytes for each interrupt).

The interrupt descriptor table (IDT) is a data structure used by the x86 architecture to implement an interrupt vector table. The IDT is used by the processor to determine the memory addresses of the handlers to be executed on interrupts and exceptions .

This block of memory is often called the Interrupt Vector Table in 8086 or the interrupt pointer table. Since 4 bytes are required to store the CS and IP values for each interrupt service procedure, the table can hold the starting addresses for 256 interrupt service routines.

2016年12月20日 · The Image Vector Table (IVT) is the data structure that the ROM reads from the boot device supplying the program image containing the required data components to perform a successful boot. # IVT包含DCD的入口点和其他的入口点，给ROM使用。 # IVT在设备中的地址是固定的，这样ROM才能够找到。

2010年12月18日 · IVT （ Interrupt Vector Table ）即中断向量表。 对于 IVT 的详细解释，这里主要参考了 Intel 公司的《 Intel® 64 and IA-32 Architectures Software Developer’s Manual Volume 3A: System Programming Guide 》、王爽先生的《汇编语言（第二版）》和张银奎先生的著作《软件调试》（书很厚，但 ...

2023年5月10日 · When the 8086 responds to an interrupt, it refers to four memory locations present in the interrupt vector table (IVT), to get the new values of CS and IP. These memory locations are used to find the starting address of the ISR of the received interrupt in the memory.

2020年12月11日 · The BIOS Interrupt Vector Table, often abbreviated as IVT, is a fundamental component of low-level system programming that plays a crucial role in the interaction between software and hardware. It serves as a pivotal link in the chain of events when a hardware interrupt occurs in a computer system.
