The constructor passes the name to the constructors of its base class (sc_module) and its simple initiator socket (dataBus), then calls the or1ksim_init function in the Or1ksim library to initialize the ISS.

The member function, run is associated with the class as a SystemC thread, using the SC_THREAD macro. It will be called automatically by the SystemC kernel after elaboration (i.e SystemC initialization).

Or1ksimSC::Or1ksimSC ( sc_core::sc_module_name  name,
                       const char              *configFile,
                       const char              *imageFile ) :
  sc_module( name ),
  dataIni( "data_initiator" )
{
  or1ksim_init( configFile, imageFile, this, staticReadUpcall,
                staticWriteUpcall );

  SC_THREAD( run );               // Thread to run the ISS

}       /* Or1ksimSC() */
