Cyclone V SoC + DDR3, Подскажите по доступу Опции

[Serb1987]

Добрый день, есть борда с циклоном 5 на борту, нужно получить доступ к памяти, но на этой борде память расположена со стороны процессорного модуля (HPS), а получить доступ нужно из логики, подскажите пожалуйста как лучше поступить или откуда копать необходимую инфу?

В Qsys уже все настроено и создан IP компонент, который потом вставлен в quartus как отдельный компонент.
