Certification Criteria for Emulation Technology in the Australian Defence Force Military Avionics Context
Reinhardt, D.
Emulation technology promises to provide a means of
addressing obsolescence issues in legacy computer
processors in the military avionics domains. It has also
been suggested that such technology might apply to safety
critical and safety related systems in these domains.
Numerous companies either have developed or are
developing software components that are capable of
emulating different legacy computing platforms. The
emulators permit the execution of legacy code on newer
computing platforms, without change to existing binary
executables or data. Subsequent modifications to the
legacy code in question may be made using either the
legacy development environment and/or with some
emulation technologies using a newer development
environment.
The Defence Science and Technology Organisation
(DSTO) is presently working with Northrop Grumman
Space Technology (NGST) to develop a concept
demonstrator utilising NGST's Reconfigurable Processor
for Legacy Applications Code Execution (RePLACE)
Emulation Technology for the Royal Australian Navy
(RAN) Seahawk Display Generator Unit (DGU). To
assess how the Australian Defence Force's (ADF's)
Technical Airworthiness Authority (TAA) - the
Directorate General Technical Airworthiness (DGTA)
might accept emulation technology, DGTA has evaluated
emulation architectures and specifically RePLACE in the
context of the Seahawk DGU. The evaluation has
considered the emulation architecture, including
identification of risks largely unique to the technology; as
well as application of ADF preferred avionics software
assurance and software safety standards to this
technology.
Evaluation of emulation technology, through exploration
of emulation architectures and RePLACE as a case study,
has allowed DGTA to define certification and regulatory
guidance for the development of emulation technology
within the ADF context.
