interrupt vector

interrupt vector
вектор прерывания
вектором прерывания называется адрес (указатель) программы обработки конкретного номера прерывания (interrupt number), находящийся в таблице векторов прерываний (IVT). Адрес начала этой таблицы известен процессору и при возникновении прерывания с данным номером управление аппаратно передаётся подпрограмме его обработки (ISR).

"In many CISC architectures there is a table of vectors that tells the processor where to jump for each of the possible conditions that could cause an exception". — Во многих CISC-архитектурах имеются таблицы векторов, чтобы процессор мог определять адрес передачи управления для каждой из возможных ситуаций, связанных с исключениями.
