Advanced Programmable Interrupt Controller LastModified: Wednesday, August 01, 2007
Abbreviated as APIC, an Advanced Programmable Interrupt Controller is a PIC used to extend the number of IRQs available, has more available interrupt lines that a typical PIC and also supports distributed CPUs. APIC must be implemented on the motherboard and also supported by the operating system. APIC differs from PIC as it offers multiple APICs on a motherboard connected via a bus system. The CPU has a LOCAL APIC and the motherboard has at least one I/O APIC.
A Description of the APIC I/O Subsystem The implementation of symmetric I/O in the FreeBSD SMP kernel is based upon the Intel Advanced Programmable Interrupt Controller (APIC). The 8259 Programmable Interrupt Controller A technique is based on interrupts and allows a system to service devices on demand (asynchronously), thereby increasing the time available to perform other processing tasks.	related categories: Configuring Adapters Integrated Circuits (ICs) related terms: CPU expansion bus I/O Intel Intel microprocessors interrupt IRQ motherboard Programmable Interrupt Controller system resource Advanced Programmable Interrupt Controller Products : Top Store Offers: FLOTECHNIC Design  149.99Kicktronic is a compact, portable electronic bass drum with a true analog sound engine.
