Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In computing, an Advanced Programmable Interrupt Controller (APIC) is a more complex Programmable Interrupt Controller (PIC) than Intel's original types such as the 8259A. APIC devices permit more complex priority schemata, and Advanced IRQ (Interrupt Request) management. One of the best known APIC architectures, the Intel APIC Architecture, has largely replaced the original 8259A PIC in newer x86 computers, starting with SMP systems when it replaced proprietary SMP solutions and on pretty much all PC compatibles since around late 2000 when Microsoft began encouraging PC vendors to enable it on uniprocessor systems and even made it a requirement of PC 2001 to enable it on desktop systems.
