Military and aerospace systems have evolved from uni-process/purpose to multi-core/functional, proprietary OS/interfaces to COTS hardware /commercial OSS software. The increasing popularity of interconnected embedded devices in the new age comes with some traditional and some recent challenges:

  • Deterministic Real-time system and high performance networking
  • Increasing adoption of Multi-core and virtualization technologies to reduce size, weight and Power (SWaP) needs.
  • System and network security and the need of long term security adherence through increasing adoption of Common Criteria standards
  • Even higher emphasis on Fault-tolerance/reliability/High-availability of the modern interconnected systems
  • Faster development cycles using commercial OSS software
  • Long life cycle support and maintainability
