An Interrupt Controller is a component that gathers hardware interrupt events from various sources and presents them to the processor, allowing for efficient handling of real-time events without the need for co
9.1.2 Hierarchical Interrupt Structure Interrupt modules are best used in a hierarchical fashion, with modules at the block level and at the chip level. Each block has its own instantiation of an interrupt module. This allows the device driver for that block to have exclusive access to the reg...
Bytes: The logical address space consists of an array of bytes with no other structure (this is sometimes called a "flat" or "linear" address space). No MMU translation is required because of a logical address is exactly equivalent to a physical address. Segments: The logical address space ...
The 8086's interrupt system inherits a lot from the Intel 8008 processor. Interrupts were a bit of an afterthought on the 8008 so the interrupt handling was primitive and designed to simplify implementation.17In particular, an interrupt response acts like an instruction fetch except the interruptin...
6.1.2 The 16F84A interrupt structure The 16F84A has four interrupt sources, all of which can be individually enabled or disabled: • External interrupt. This is the only external interrupt input. It shares a pin with Port B, bit 0 (Figure 2.1). It is edge triggered. • Timer overfl...
Vector Table Structure All processors provide mechanisms to translate an interrupt or exception into a handler for the interruption. Different processor architectures provide differing levels of hardware support in identification of the underlying hardware exception. As we mentioned above, external hardware ...
In vectored interrupting, a special block of memory is typically reserved to accommodate a data structure called an interrupt vector table—a table with a sequence of entries called interrupt vectors. Each interrupt vector contains information that points the processor to the start address of the cor...

1. An interrupt system for use with each processor of a multiprocessor communication or telephone network, where one processor may request actions of another responding processor independent of the state of the other processors, said system comprising ...
