Understanding Linux Network Internals: Frame Reception: This paper discusses about frame reception, where the hardware uses an interrupt to signal the CPU about the availability of the frame. The IRQ number causes the right handler to be invoked. The handler is typically a function within the device driver registered at device driver initialization time. IRQ function...; Tags: Linux, Network, Device Driver, O'Reilly Media Inc., Handler; Book chapters 2006-01-19
Cisco - Cisco 3600 Series Router Architecture: This paper describes the hardware and software architecture of the 3600 Series Routers. The system controller helps the main processor with device control, interrupt handling, counting/timing, data transfer, and communication with slower Input/Output (I/O) devices, and dynamic RAM DRAM. The system controller contains the cache, Flash, DRAM, PCI, and Interrupt...; Tags: DRAM, Router, I/O, Cisco Systems Inc., System Controller, Memory, Semiconductors, Hardware, Components; White papers 2004-06-17
MetaTM/TxLinux: Transactional Memory for an Operating System: This paper quantifies the effect of architectural design decisions on the performance of TxLinux. TxLinux is a Linux kernel modified to use transactions in place of locking primitives in several key subsystems. The authors run TxLinux on MetaTM, which is a new Hardware Transaction Memory HTM model. MetaTM contains features...; Tags: Operating System, Memory, Association For Computing Machinery, TxLinux, MetaTM; White papers 2007-03-30

Which device is constantly interrupting?: I have a w2k server (build 5.00.2195 sp4) on a dual CPU IBM x225 with 2.5 gig RAM. The performance tab in taskmanager shows one CPU constantly up around 100% in kernel mode red. The processes tab shows 'system' (pid 8) taking up most time (25 to 30% cpu). I...; Tags: IRQ; Q&A 2005-08-24
Real-Time Java, Part 4: Real-Time Garbage Collection: Real-Time RT application development distinguishes itself from general-purpose application development by imposing time restrictions on parts of the runtime behavior. Such restrictions are typically placed on sections of the application such as an interrupt handler, where the code responding to the interrupt must complete its work in a given time...; Tags: Application Development, Java, Garbage Collection, Software Development, Development Tools, Middleware, Software/Web Development, Enterprise Software, Software; White papers 2007-05-02

Minimizing Risk in an Interrupt-Driven World: Life in the Outbound Call Center Regulatory and Policy Compliance Management: It's the classic outbound Call Center problem. The interrupt-driven, unpredictable nature of the business means even the most button-down and best operational plans and strategic direction can change on a dime. This gives little time to react and a lot of room for error. Especially if these changes are managed...; Tags: Call-center, Compliance, Austin Logistics, Call Centers, Customer Relationship Management (CRM), It Operations, Enterprise Software, Software; White papers 2007-09-11
Understanding interrupts and memory addresses in Windows 98: Even with today's plug-and-play devices, conflicts with memory addresses and interrupts are common. In this Daily Drill Down, Talainia Posey explains how Windows 98 uses interrupts and memory addresses.In the days of plug-and-play systems, many people assume that trouble with memory addresses and hardware interrupts is a thing of the...; Tags: Talainia Posey, Microsoft Windows, interrupt, memory address, expansion card, IRQ, Microsoft Windows 98; Technical articles 2000-09-05
Writing complex interrupt handlers in C: Although it means a little extra overhead, you can write interrupt service routines ISRs in C. If you're writing a complex interupt handler, it may be worth it.Although interrupt service routines ISRs are frequently written in assembler, it's easier to handle complex interrupts by writing the body of the ISR...; Tags: C/C++, Development tools, David Brenan, interrupt service routine, compiler, C, interrupt, register; Technical articles 2002-09-09
