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...

Many paths in PlanetLab cannot be measured by Pathload. One of the main reasons for this is timing irregularities caused by interrupt moderation of network hardware, which delays generation of interrupts for a certain period of time to reduce per-packet CPU overhead. Motivated by this problem, we study Pathload in detail under various end-host interrupt delays and find that its trend detection ...

The paper presents a system for manner-based labelling of the speech signal for isolated words from total energy profile. The manner-based classes selected are sibilant, vowel, nasal murmur, semi vowel and lateral, trill, unvoiced unaspirated interrupt, unvoiced aspi rated interrupt, voiced unaspirated interrupt , voiced aspirated interrupt and consonant clusters. The results of labeHing for 10...

Purpose The impact of the COVID-19 pandemic on crime has been highly variable. One possible source variation runs indirectly through that had groups tasked with preventing and responding to crime. Here, this paper aims examine activities undertaken by front-line workers in City Los Angeles Mayor’s Office Gang Reduction Youth Development (GRYD). Design/methodology/approach authors use both autor...

An operating system usually distinguishes between threads managed by a software scheduler and interrupt service routines, scheduled and dispatched by an interrupt controller. This paradigm has inherent problems for real-time systems as low-priority interrupt routines can interrupt high-priority threads. The Sloth concept proposes to overcome this issue by implementing both interrupt handlers an...

This paper describes the implementation and performance of M-VIA on the AceNIC Gigabit Ethernet card. The AceNIC adapter has several notable hardware features for high-speed communication, such as jumbo frames and interrupt coalescing. The M-VIA performance characteristics were measured and evaluated based on these hardware features. Our results show that latency and bandwidth improvement can b...

Threaded interrupt handling is a common technique used in real-time operating systems since it increases system responsiveness and reduces priority inversions. The PREEMPT RT Linux kernel patch introduces aggressive threaded interrupt handling into the Linux kernel. However, under PREEMPT RT, interrupt handling threads must be assigned a single fixed scheduling priority. This can become a signi...
