AIMS Processing Architecture
l Shared processor architecture mandates:
– Robust software partitioning
– High throughput processing
– Increased reliability
l Eightprocessing modules per shipset
provide redundancy
– Four unique hardware part numbers per shipset
– Basic
– Graphic generation
– Communication
– Memory (ACMF)
Fail Safe Partitioning
l Required to be able to certify highly
integrated architecture
l Allows software changes without
reverification of unmodified functions
l Allows intermix of software criticalities on
same processor
l Verification restricted to target criticality

Fail safe partitioning provides a high integrity

operating environment in which the actions of one
function will not impact the operation of another
