“…These projects, however, were not widely accepted because of different standards. With the development of embedded technique and bus technique, researchers began to focus on new strategies such as hardware platforms (Shao and Sun, 2007; Marcu et al , 2008), interfaces (Blomdell et al , 2005; Naumann et al , 2007) and communication methods (Sarker et al , 2006; Regenstein et al , 2007) for OARC. The implementation of these approaches always requires prerequisite knowledge and mountains of work on hardware and software.…”
