In a computer, the Advanced Configuration and Power Interface ( ACPI) provides an open standard that operating systems can use to discover and configure computer hardware components, to perform power management by ( for example) putting unused components to sleep, and to perform status monitoring. First released in December 1996, ACPI aims to replace Advanced Power computing, Intel' s Advanced Programmable Interrupt Controller ( APIC) is a family of interrupt controllers.
As its name suggests, the APIC is more advanced than Intel' s 8259 Programmable Interrupt Controller ( PIC), particularly enabling the construction of multiprocessor systems. It is one of several architectural designs intended to solve interrupt routing efficiency issues in multiprocessor.
