tricore

TriCore is a 32-bit microcontroller and microprocessor architecture developed by Infineon Technologies. It is designed for high-performance, real-time automotive applications, combining a central 32-bit TriCore CPU core with an integrated digital signal processing (DSP) engine and a rich set of peripherals in a single device.

The architecture aims to deliver deterministic timing, combined computational power for control and signal processing, and high safety features. It typically includes on-chip flash, RAM, and peripheral buses that support real-time I/O and memory protection, enabling reliable operation in demanding environments.

TriCore devices include automotive interfaces such as CAN and Ethernet and may incorporate LIN, FlexRay, or other protocols depending on the model; safety features such as watchdogs, error-correcting memory, and fault-tolerant reporting are commonly supported. The architecture is designed to support both control-oriented tasks and signal processing, making it suitable for engine management, braking, chassis, and other automotive functions.

History and usage: TriCore was introduced by Infineon in the late 1990s as a scalable platform for automotive electronic control units. It later formed the basis of Infineon’s multi-core AURIX family, which extends the TriCore concept into higher performance and safety-rated products while preserving real-time determinism and integration.

Development and tools: Infineon and third-party toolchains provide support for TriCore development, including compilers, debuggers, and integrated development environments. These tools facilitate code generation, debugging, and validation, including safety-focused workflows and hardware-in-the-loop testing.
