Claim: Infineon TriCore is a heterogeneous, asymmetric dual core architecture with a peripheral control processor and has been on its fourth generation in 2011.
Evidence: TriCore is a heterogeneous, asymmetric dual core architecture with a peripheral control processor that enables user modes and core system protection. 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/MCU/DSP microcontroller core," called TriCore, which is as of 2011 on its fourth generation, called AUDO MAX (version 1.6).
