Migrating legacy software from obsolete hardware to modern system environments
Virtualization software and model-based design provide a path that not only enables system designers to maintain legacy software for avionics and other mission-critical systems but also makes it possible to migrate that code to modern higher-performance processing platforms, for example from an older PowerPC-based VME board over to a new x86 or Arm-based VME or OpenVPX module.
