WebCPU is a busy taskmaster. Any subsystem requiring the attention of the CPU generates Interrupt. INTERRUPT (INT) is both a control and status signal to the CPU. Generally, the memory subsystem does not generate Interrupt. The Interruption alters the CPU execution flow. Recognising and servicing Interrupts is fundamental to any processor design. Interrupts may be implemented in hardware as a distinct component with control lines, or they may be integrated into the memory subsystem . If implemented in hardware as a distinct component, an interrupt controller circuit such as the IBM PC's Programmable Interrupt Controller (PIC) may be connected between the interrupting device and the processor's interrupt pin to multiplex several sources of interrupt onto the one or two CP…

WebA rough deﬁnition of interrupt is that: interrupt is a mechanism by which computer compo-nents, like memory or I/O modules, may interrupt the normal processing of the processor and request the processor to perform a speciﬁc action.
