A Highly Integrated RISC-V Based SoC for On-Board Unit in ETC System
Xinchao Zhong, Chiu‐Wing Sham, Longyu Ma · 2021 IEEE 10th Global Conference on Consumer Electronics (GCCE) · 2021
A highly integrated system-on-chip for the on-board unit in the electronic toll collection system is presented. It is based on RISC-V core and integrates a 5.8 GHz transceiver, a 13.56MHz NFC reader, a BLE module and other modules. The presented SoC provides primary functions for designing an on-board unit with 5.8 GHz DSRC, Bluetooth and NFC connectivity. To our knowledge, this SoC is the most highly integrated chip for the OBU. It can connect the OBU to the ITS system to improve the customer experience and make more applications possible while reducing the cost and profile of OBUs.
