Advanced Peripheral Interrupt Controller (APIC) The APIC unit inside the CPU, along with an I/O APIC unit, facilitates multiprocessor interrupt management. The APIC works with multiple I/O subsystems where each subsystem has its own interrupts which help minimize centralized system overhead. Bus Controller The bus controller integrated in the Pentium Pro processor controls the system bus, allowing it to efficiently perform its functions. It ensures the bus serves as a reliable interconnect

System Bus The system bus is the CPU’s major connection to all the system devices, primarily the PCI and EISA bridges, and the memory controller. It can handle as many as eight outstanding transactions at a time through a transaction pipelining feature, in which consecutive tasks from the CPU are queued in and transported to the designated devices on a first-in first-out basis. Pipelining allows for transaction overlapping in different phases, as the CPU does not have to wait for each to com
