TriCore is a32-bitmicrocontroller architecture fromInfineon. It combines aRISC processor core, a microcontroller, and aDSP in onechip package.
In 1999,Infineon launched the first generation ofAUDO (Automotive unified processor) which is based on what the company describes as a 32-bit "unifiedRISC/MCU/DSP microcontrollercore", called TriCore, which as of 2011 is on its fourth generation, called AUDO MAX (version 1.6).
TriCore is a heterogeneous, asymmetric dual core architecture with a peripheral control processor that enables user modes and core system protection.
Infineon's AUDO families[1] target gasoline and dieselengine control units (ECUs), applications inhybrid andelectric vehicles as well as transmission, active and passive safety and chassis applications. It also targets industrial applications, e.g. optimized motor control applications and signal processing.
Different models offer different combinations of memories, peripheral sets, frequencies, temperatures and packaging. Infineon also offers softwareclaimed to help manufacturers meet SIL/ASIL[2] safety standards. All members of the AUDO family are binary-compatible and share the same development tools. AnAUTOSAR library that enables existing code to be integrated is also available.
Infineon's portfolio includes microcontrollers with additional hardware features as well as SafeTcore safety software and a watchdog IC.[3]
AUDO families cover safety applications including active suspension and driver assistant systems and also EPS and chassis domain control. Some features of the product portfolio are memory protection, redundant peripherals, MemCheck units with integrated CRCs, ECC on memories, integrated test and debug functionality andFlexRay.
