摘要：
A processing resource apparatus comprises a reference processing module comprising a set of reference stateful elements and a target processing module comprising a set of target stateful elements. A scan chain having a first mode for supporting manufacture testing is also provided, the scan chain being arranged to couple the reference processing module to the target processing module. The scan chain also has a second mode capable of synchronizing the set of target stateful elements with the set of reference stateful elements in response to a synchronization signal.
