TriCore™ for Body Applications
Body electronics systems embrace a broad variety of applica-
tions inside the car, covering comfort, safety and security as
well as high-performance computing and in-vehicle network-
ing. This leads to the key strengths of the AURIX™ family:
AUTOSAR – With AUTOSAR 4, multicore architectures
can be easily designed into vehicles. Infineon is one of
the first implementers of a multicore architecture with
AURIX™ ready for AUTOSAR 4.x. Furthermore, Infineon also
provides the MCAL drivers developed according to CMM 3
level.
Power Consumption – Innovative supply concept
automatically adapts the power consumption to the
actual performance needs. Furthermore, the new trend
of pretended networking and ECU degradation is actively
supported.
Enhanced communication – As cars incorporate an
increasing amount of electronics, the body electronics
module’s responsibilities increase to handle the additional
components and message trac. Because of the gateway
functionality of the BCM, the AURIX™ has enhanced
communication capabilities to support communication
between CAN, LIN, FlexRay™ and Ethernet buses.
Safety – The trend is toward the integration of safety
targets in the requirements of advanced body systems
such as lighting, BCM etc. To achieve the required ASIL
level according to ISO 2626, AURIX™ has the capability to
cover targets up to the highest safety integrity level ASIL-D.
Security – In the future, the need for a high level of
security will also expand into body applications. Cars are
expected to hold even more information as they become
smart cards on wheels to simplify financial transactions
at gas pumps, charging stations, parking lots, toll booths,
drive-through shops and more. The vehicle will act as a
smart card and pay your fee/fare – sometimes automati-
cally. Hardware-based security is more robust than soft-
ware-only security. AURIX™ provides a dedicated module,
HSM (Hardware Secure Module), to cover the highest level
of security.
