Continued processing of out-of-order non-architectual operations upon exceptions until flushing by architectual operations exceptions to avoid resume deadlock

摘要

A data processing device having an apparatus to execute operations out-of-order. The apparatus having an execution unit to execute the set of operations out-of-order. The execution unit, upon executing an operation that generates a first exception, continues to execute operations out-of-order, to avoid deadlock, until an operation of a first type is to be executed. The execution unit flushes a pipeline once the operation of the first type is to be executed.
