AURIX™ TC4x Architecture Block Diagram

Thanks to the hardware virtualization performance of AURIX™ TC4x, multiple different ECU functions can be independently run on a TC4x chip by deploying virtual machine software without interfering with each other. AURIX™ TC4x virtualization will be explained in a subsequent article.

Infineon has many years of experience in information security development and has deployed hardware security modules (HSM) since the first generation of AURIX™ chips. Now the development of AURIX™ TC4x is fully in accordance with the ISO21434 information security standard. At the same time, Infineon has obtained the ISO21434 product development process certification issued by an authoritative third party.

The introduction of the parallel processing unit (PPU) in AURIX™ TC4x will help it expand its application scenarios in the field of embedded AI. For example, PPU can play a key role in high-security intelligent prediction and intelligent control in multiple applications such as domain controllers/regional controllers, ADAS, and new energy vehicles. For further introduction to PPU, please pay attention to subsequent related special articles.

Infineon has built a comprehensive development tool chain and software ecosystem for AURIX™ TC4x. Development tools include compilers, debuggers, integrated development environments (eg ADS Limited), virtual prototypes (VDK), model simulation hardware support packages, etc. The software ecosystem includes hardware low-level drivers (MCAL), AUTOSAR protocol stacks, functional safety software libraries (SafeTlib), information security software, PPU software libraries, CDSP software libraries, etc.

The next-generation power management chip TLF4 series PMIC, which is the best match for AURIX™ TC4x, will also be launched simultaneously, helping to further improve the safety performance of automotive controllers. Stay tuned.
