FPGA-based ECU design conforming to AUTOSAR and ISO26262 standards
The AUTOSAR standard, developed by several automotive manufacturers in 2003, aims to define a standard system software architecture for ECUs distributed in vehicles. The purpose of the ISO 26262 standard is to focus on functional safety, essentially to avoid or detect and handle faults, thereby mitigating the effects of failures and preventing violations of any existing system safety objectives. Functional safety has become one of the key issues in automotive development with the introduction of new safety-critical features such as driver assistance or dynamic control. The ISO26262 standard was approved in 2011 to support the development of hardware and software security.
AUTOSAR layered model from MCU to application layer
The AUTOSAR and ISO26262 standards are mainly from the perspective of software development, and are oriented to the computing platform based on the microcontroller unit. Although standard MCUs are often the best choice for automotive ECU hardware platforms, with the ever-decreasing cost of new FPGAs and the integration of hard-core processors within some FPGA products, FPGA devices have become widely used in this market. The ideal solution. In addition, the trend of continuously integrating new embedded features in automobiles has also raised the need for parallel computing architectures. This is especially true in today's in-vehicle infotainment industry where high-speed digital signal processing is opening the door to FPGA technology. ã€detailed】
