  • Advanced Programmable Interrupt Controller

    Connected From This APIC 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 models, and Advanced IRQ (Interrupt Request) management. In computing, a programmable interrupt controller (PIC) is a device that is used to […]
