Avionics Architecture evolution – a short history
A320/340A310
In 1970’s and 1980’s, 2 major trends:
� Increase of complexity� Increase the number of equipments installed on aircraft
� Increase the number of wires to interconnect all equipments
� Higher level of requests and constraints� Time to market (including management of obsolescence)
� Safety
� Performances
� Maintenance costs

Between 1990’s and 2000’s, a new step is reached:capability to integrate several applications inside a common unit
� IMA is identified as a concept permitting to� Reduce the number of equipments installed on aircraft � Integration
� Reduce the number of types of equipments installed on aircraft � Modularity and costs
� Reduce the number of connexions � Simplicity

15 /15 / From IMA1G/IMA1G+ to IMA2G : SCARLETT Objectives
Increase operational reliability
Avoid unscheduled maintenance
Reduce Set of Part Numbers
Scalability to various aircraft
types
Reduce development
cycle
Reduce cost of spare parts
1 – Provide a scalable solution
2 – Define minimal set of modules3 – Increase number of supported
function4 – Develop new standards to
support 2 nd generation IMA
5 – Provide associated process and toolset
6 – Demonstrate fault tolerance
-- and reconfiguration
Save weight, volume, power consumption
16 /16 / IMA2G improvements
IMA1G
� Is only used for selected applications
� Characterized by several types of processing Module s because of Input / Output
� Does authorize better reuse and less Part Numbers b ut not re-configurability
IMA1G+
� Performance upgrading to sustain more functions
� Upgrade Operating System with separation between Lo cal and Global variable
� Generalization of Incremental Certification
IMA2G
� Will separate Input / Output from computing resourc e
� Will bring enhanced performance enabling a greater number of applications to be hosted on the same module
� Will provide specific platform services such as rec onfiguration
� Will enable scalability
