(a) The interrupt vector table for the Intel microprocessor; (b) the contents of an interrupt vector. In an interrupt vector table, the first five interrupt vectors are identical in all Intel microprocessor family members, from the 8086 to the Pentium. Other interrupt vectors exist for the ...
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. After that, we will see the interrupt vector table o...

and an execution unit fetching the interrupt vector information in response to the vector fetching command information, the execution unit thereby initiates an interrupt operation by use of the interrupt vector information and returning interrupt acknowledge information as a part of the interrupt operation...
The protected mode interrupt handler then determines the segment:offset of the entry point to the V86 (or real mode) interrupt service routine required to service this second hardware interrupt from the interrupt vector table in step 166. The CS:EIP of the copied VMTF on the top of the ring...
The 8086 switched to an interrupt vector table, but retained some 8080 interrupt characteristics for backward compatibility. In particular, the 8086 performs a memory cycle very much like an instruction fetch, but instead of an instruction, it receives an interrupt number. The 8086 performs two int...
8086 microprocessor which services interrupt requests by using an 8-bit vector to select an interrupt service routine address from a table of addresses stored in a contiguous area of memory. Depending on which type of microprocessor the 8259A is programmed for, in response to an interrupt request...

A vector interrupt system provides an RISC microprocessor provided with a prefetch enable mode and a prefetch disable mode for direct support of a real-time operation system which includes an ability to enqueue interrupts in a hierarchical order during execution of the prefetch-disable operation mode...
