1This directory contains a demo of C++ configuration of gem5. The intention 2is to provide a mechanism to allow pre-generated config.ini files generated 3by Python-based gem5 to be reloaded in library-base versions of gem5 4embedded in other systems using C++ calls for simulation control. 5 6This directory contain a demo of hosting a C++ configured version of gem5 7onto SystemC's event loop. The hosting is achieved by replacing 'simulate' 8with a SystemC object which implements an event loop using SystemC scheduler --- 12 unchanged lines hidden (view full) --- 21 sc_module objects. 22 stats.{cc,hh} -- Stats dumping (copied from util/cxx_config) 23 24Read main.cc for more details of the implementation and sc_... files for 25 26To build: 27 28First build gem5 as a library with cxx-config support and (optionally) |
