適用范圍：This standard defines the functionality and principle interfaces for the Common Functional Module (CFM) toensure the interoperability of Common Functional Modules and provides design guidelines to assist inimplementation of such a CFM. It is one of a set of standards that define an ASAAC (Allied Standard AvionicsArchitecture Council) Integrated Modular Avionics System.This definition of interfaces and functionality allows a CFM design that is interoperable with all other CFM tothis standard, that is technology transparent, that is open to a multi-vendor market and that can make the bestuse of COTS technologies.Although the physical organisation and implementation of a CFM should remain the manufacturer’s choice, inaccordance with the best use of the current technology, it is necessary to define a structure for each CFM inorder to achieve a logical definition of the CFM with a defined functionality. This definition includes:? The Generic CFM, which defines the generic functionality applicable to the complete set of CFMs. Thegeneric functionality is defined in 4.1.? The processing capability, which defines the unique functionality associated with each CFM type withinthe set. This functionality is defined in 4.3.? The logical and physical interfaces that enable CFMs to be interoperable and interchangeable, these aredefined in Clause 6.? The functionality required by a CFM to support the operation of the System is defined in Clause 6.
