Reconfigurable ECU communications in Autosar Environment

Reconfigurable architectures become popular in consumer applications as they require low Non-Recurring Engineering costs. Certain FPGA families provide the Dynamic Partial Reconfiguration (DPR) mechanism which allows to modify parts of a device on-the-fly. The high reliability constraints in automotive systems requires safe communications between ECUs (Electronic Control Unit). This paper presents a support for fault-tolerant communication modes among ECUs by the use of the dynamic reconfiguration paradigm. Also in this paper, a method of integrating dynamic reconfiguration in Autosar environment is presented.
