ABSTRACT

Avionics architectures have evolved over time as avionics have become more and more integrated. Within traditional architectures, an aircraft function was typically allocated to a redundant set of line-replaceable units (LRUs) where the function was wholly contained by an LRU. This chapter describes that the genesis platform represents the foundational architecture used by the Boeing 787 and other aircraft. The Boeing 787 includes a good example of integrated modular avionics (IMA) architecture. The Genesis platform is a hardware/software platform that provides computing, communication, and input–output services for implementing real-time embedded systems, known as hosted functions. Multiple systems can be architected and overlaid on the partitioned platform resources to form a highly integrated system with the unique characteristic of full isolation and independence of each individual system. The Boeing 787 and other aircraft have already chosen to utilize the Genesis architecture to achieve an IMA solution.
