[/ˌɪntəˈrʌpt ˈmæskɪŋ/]
noun
mascaramento de interrupções
1. A technique in computer programming and digital systems where certain interrupt signals are temporarily disabled or blocked to prevent them from being processed by the CPU, allowing critical code sections to execute without interruption
The operating system uses interrupt masking to protect critical sections of code from being interrupted by hardware signals.
O sistema operacional usa mascaramento de interrupções para proteger seções críticas de código de serem interrompidas por sinais de hardware.
2. The process of setting interrupt mask registers to control which interrupts are allowed to interrupt the processor at any given time
Interrupt masking is essential in real-time systems to ensure predictable timing behavior.
O mascaramento de interrupções é essencial em sistemas em tempo real para garantir um comportamento de tempo previsível.
This is a specialized technical term primarily used in computer science, embedded systems programming, and operating systems development. It is universally understood in technical communities across Brazil, Portugal, and English-speaking countries. The concept is critical in real-time systems and low-level programming where timing and data consistency are crucial. No colloquial or regional variations exist for this term as it maintains consistent technical usage across different regions.
