A RISC-V Based SoC with Configurable CPK Sensor Interface for ECU on Motorcycle

Abstract

A RISC-V based SoC (system on chip) with a configurable crankshaft position sensor (CPK) interface for an engine control unit (ECU) on a motorcycle is presented. The proposed SoC is the first SoC with RISC-V core for a motorcycle ECU, integrating a dedicated configurable engine crank position sensor interface to facilitate accurate and lowlatency fuel injection and ignition control for the internal combustion engine on a motorcycle, while greatly reducing the computational capability demand for the MCU inside the ECU.
