But also the cool bits!\n\nHave you ever wondered why anybody would ever have a need for a *\"Compare and swap and triple store\"* instruction?\n\nWhat about a *\"Rotate then or selected bits\"* instruction?\n\nAnd what about vector BCD instructions? Or decimal floating point?\n\nHave you ever wondered how an architecture would look like if it could access 16 distinct address spaces at the same time? Or... why?\n\nNo?  *We don't care*!  We will present those (and many more) instructions and features anyway!","original_language":"eng","persons":["Claudio Imbrenda","Janosch
