superscalar architecture

superscalar architecture
суперскалярная архитектура
архитектура процессора с несколькими конвейерами, предусматривающая возможность одновременного выполнения более одной обычной машинной (скалярной) команды, т. е. эти команды запускаются в процессоре на выполнение одновременно и выполняются независимо друг от друга на разных конвейерах. При этом часть полученных результатов может не использоваться в общем вычислении и отбрасываться (обычно из-за ветвлений программы). Применяется как в RISC-, так и в CISC-процессорах. Термин впервые появился в 1987 г.
