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...
PURPOSE:To change a vector address easily by latching preliminarily the vector address designated optionally by a microprocessor in a latch circuit and fetching it into the microprocessor when an interrupt signal is given. CONSTITUTION:An optional vector address is designated preliminarily by a ...
(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 ...

microprocessor or microcomputer, the operation of which is determined by a stored program, different stored programs being utilized for each game or set of games. In one embodiment, the microprocessor is contained within the module 11 and a read-only memory containing a particular stored program ...
The disclosure relates to a re-vectoring circuit of a microprocessor system wherein pending interrupts are serviced without unnecessary microprocessor state store and restore operations associated with a return-from-interrupt instruction. At the conclusion of an interrupt service routine, an indirect jump...

One subsystem includes apparatus for receiving commands requiring a priority interrupt by storing vectors in a random access memory. These vectors which are addressed by the channel number of the interrupting subsystem indicate the offset to be added to the base address of an exception vector table....
