instruction set simulator

instruction set simulator
= ISS
система моделирования набора команд, имитатор [процессора, набора команд]
программа, используемая для разработки или оценки ПО и тестов для встраиваемых систем. По степени сложности различают три типа имитаторов
1) простейшие (instruction-accurate ISS - с точностью до команд), только исполняющие команды процессора. При этом игнорируются эффекты конвейеризации и подсчёт машинных циклов, затрачиваемых на исполнение команд
см. тж. ICE
2) более сложные версии (timing-accurate ISS - с точностью до временной диаграммы) подсчитывают и число циклов, но могут игнорировать задержки при доступе к кэш-памяти и MMU
3) сложные (cycle-accurate ISS - с точностью до тактов) в точности моделируют поведение целевого процессора
