Two strategies for supporting asynchronous interrupts are: the use of the processor's hardware interrupt system and the use of polling. The advantages of polling include: portabil-ity, simplicity, and low cost for handling interrupts. Unfortunately , polling has an overhead for the explicit interrupt checks inserted in the code. This paper describes balanced polling, a method for placing the in...

Background: Vaccination against COVID-19 is as a key solution to interrupt its spread. This study aimed to describe the vaccination coverage required to stop the spread of COVID-19 in Sri Lanka using a mathematical modeling strategy. Materials & Methods: This longitudinal study used age-stratified and unstratified Susceptible-Infectious-Recovered (SIR) models. Data on the population's age dist...

Microprocessors and microcontrollers are now widely used in automobiles. Microprocessor systems contain sources of interrupt and interrupt service routines, which are software components executed in response to the assertion of an interrupt in hardware. A major problem in designing the software of microprocessor systems is the analytical treatment of interrupt latency. Because multiple interrup...

We study the problem of determining stack boundedness and the exact maximum stack size for three classes of interrupt-driven programs. Interrupt-driven programs are used in many real-time applications that require responsive interrupt handling. In order to ensure responsiveness, programmers often enable interrupt processing in the body of lower-priority interrupt handlers. In such programs a pr...

Interrupt processing can be a major bottleneck in the end-to-end performance of Gigabit networks. The performance of Gigabit network end hosts or servers can be severely degraded due to interrupt overhead caused by heavy incoming traffic. In particular, excessive latency and significant degradation in system throughput can be encountered. Also, user applications may livelock as the CPU power ge...

Interruption is a useful feature in programming and specification languages. Therefore, process algebras has been extended with an additional interrupt operator. We invent a class of event structures, called interrupt event structures, to give a true concurrent semantic to process algebras containing interruption. Interrupt event structures are more expressive than other event structures with r...
