摘要：
A microcomputer which obtains a rotor position signal from a biphase signal delivered by a resolver mounted on an electric motor according to a rotation phase of a rotor relative to a stator, thereby controlling the motor based on the rotor position signal. The microcomputer includes a digital signal converter which is configured by hardware and converts the biphase signal delivered from the resolver into a digital data position signal, the digital signal converter being mounted on a single chip.
