Hi, all, I am trying to understand the O3CPU code. But I find that the template policy is heavily used in O3CPU and I am quiet confused about this part. Like the load store queue, the lsq_unit.hh file has all the class declaration of lsq_unit, but in the lsq_unit.cc file, there is only one statement “template class LSQUnit<O3CPUImpl>;”. My understanding is that all the functions in lsq_unint.hh are actually defined/implemented in lsq_unit_impl.hh files. The O3CPUImpl is actually defined in impl.hh file. But what the lsq_unit.cc file is actually doing? And what is the design model behind this template usage? Does anyone know about this part. Thanks so much.
