interrupt vector
[ɪn'tərəpt 'vektər]
nounpl: interrupt vectors
vetor de interrupção
1. A memory address that points to the location of an interrupt handler routine in a computer system
When an interrupt signal is received, the CPU looks up the corresponding interrupt vector to find the address of the appropriate handler.
Quando um sinal de interrupção é recebido, a CPU procura o vetor de interrupção correspondente para encontrar o endereço do manipulador apropriado.
2. A table entry that stores the starting address of an interrupt service routine
The interrupt vector table is located at the beginning of memory in many microcontroller systems.
A tabela de vetores de interrupção está localizada no início da memória em muitos sistemas de microcontrolador.
3. The mechanism used by the processor to determine which interrupt handler to execute when an interrupt occurs
The interrupt vector provides the connection between the hardware interrupt and the software routine that handles it.
O vetor de interrupção fornece a conexão entre a interrupção de hardware e a rotina de software que a manipula.
This is specialized technical terminology used primarily in computer science, embedded systems programming, and electrical engineering contexts. The term is universally understood in both Brazilian and Portuguese technical communities, and there are no significant regional variations in its usage. It is commonly taught in computer architecture courses at universities in Brazil and Portugal.
