    195195Get the size for a given register. This is defined in GDB

     200=== executeNCycles semantics ===
     201
     202When executeNCycles is called, instruction and data requests previously retrieved through getRequests() may not be satisfied yet.
     203
     204As executeNCycles ensures responses MUST NOT change for at least ncycle:
     205 * an ISS frozen because of I or D miss SHOULD do nothing externally visible for at least ncycle. Iss SHOULD internally simulate a stall of ncycle and return ncycle.
     206 * an ISS running because all its instruction and data accesses are satisfied SHOULD run as long as no other request needs to be answered by cache.
