Non-uniform memory access (NUMA) computer system includes at least two nodes interconnected by node, wherein the at least one node comprising a processor for interrupt service. 把这些节点分割成多个外部中断域,从而总是把外部中断提交给其中出现该中断的外部中断域内的处理器. These nodes are divided ...

Vectors Interrupt in computer science refer to a table of addresses of Interrupt Service Routines (ISRs) that manage multiple interrupts in microprocessors. These ISRs are implemented as functions in high-level languages like C or C++, making the code easier to read and maintain compared to assembl...
What do I mean by cascading IRQs in computer systems? Cascading IRQs involve using one IRQ line to manage several IRQs simultaneously. In older systems with limited IRQ lines, this technique allowed multiple devices to share a single IRQ. However, modern systems and advanced architectures have mad...
The next step in architecture development was namedx2APIC. The number of possible CPUs in the system was increased to 2^32. These controllers can work in a backwards compatibility mode with xAPIC, or they can work in the new x2APIC mode. In this new mode controller programming is not do...
high-end systems use switch rather than bus architecture. On these systems, multiple components can talk to other components concurrently, rather than competing for cycles on a shared bus. In this case,DMA is even more effective. Figure 1.5 shows theinterplay of all components of a computer ...
Storage device controllers generally interface with one or more host devices via one of various host computer interface protocols such as, for example, Serial Advanced Technology Attachment (SATA), in accordance with the Serial ATA 2.6 Specification (February 2007), hereinafter, “SATA protocol”, av...
One interconnect fabric architecture includes the Peripheral Component Interconnect (PCI) Express (PCIe) architecture. A goal of PCIe is to enable components and devices from different vendors to inter-operate in an open architecture, spanning multiple market segments; Clients (Desktops and Mobile), Se...
