In a calculation processing device of a resolver signal, a processing speed of the resolver signal is increased, and a noise-proof characteristic thereof and also reliability thereof are improved, while total system cost is reduced. The resolver signal calculation processing device is arranged such that a resolver signal output from a resolver is digitally converted by a resolver interface into a digital rotary angle signal; the digitally-converted rotary angle signal is processed by a central calculation processing unit; and the resolver interface is provided within the resolver signal calculation processing device.
