'''TriCore''' is a [[32-bit]] [[microcontroller]] architecture from [[Infineon]]. It unites the elements of a [[RISC]] processor core, a microcontroller and a [[Digital signal processor|DSP]] in one [[Chip carrier|chip package]].

==History and background==
In 1999, [[Infineon]] launched the first generation of '''AUDO''' (Automotive unified processor) which is based on what the company describes as a 32-bit "unified [[RISC]]/[[Microcontroller unit|MCU]]/[[Digital signal processing|DSP]] microcontroller [[CPU|core]]", 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<ref>[http://www.infineon.com/cms/en/product/channel.html?channel=db3a304326dfb1300126fb4d072b3f2b Infineon’s AUDO families]</ref> target gasoline and diesel [[engine control unit]]s (ECUs), applications in [[hybrid vehicle|hybrid]] and [[electric 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 software

All members of the AUDO family are binary-compatible and share the same development tools. An [[AUTOSAR]] library that enables existing code to be integrated is also available.

==Safety==
Infineon's portfolio includes microcontrollers with additional hardware features as well as SafeTcore safety software and a watchdog IC.<ref>{{Cite web |url=http://www.infineon.com/cms/en/product/microcontrollers/safety-products-pro-sil%3F/cic61508-signature-watchdog/channel.html?channel=db3a30432e5d3808012e6b256d5326f5 |title=Infineon's CIC61508 Signature Watchdog |access-date=2011-04-13 |archive-url=https://web.archive.org/web/20110517093647/http://www.infineon.com/cms/en/product/microcontrollers/safety-products-pro-sil?%2Fcic61508-signature-watchdog%2Fchannel.html%3Fchannel=db3a30432e5d3808012e6b256d5326f5 |archive-date=2011-05-17 |url-status=dead }}</ref>

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 and [[FlexRay]].
