Therefore, if the interrupt is to be reduced to about 10% or less of the CPU load, the CPU needs an operation speed of about 1 GHz. Become. The operating speed of the CPU is technically possible, but power consumption increases. When considering motor control in an electric vehicle, there are periods during which the motor rotates at a medium speed to a high speed and periods during which the motor rotates at a low speed, and the CPU is excessive during the stop-low speed rotation period. Since it has processing capability, wasteful power consumption of the CPU occurs.

Therefore, the power consumption can be further reduced.
- FIG. 12 is an explanatory diagram showing an example of a technique for correcting a resolver value by the resolver value correction calculation circuit 5.
- the resolver value correction arithmetic circuit 5 uses a Z-phase signal Z (Z-phase input), a compare signal, a timer, etc. to generate a fixed period, and an ideal resolver value (dotted line). The correction value is calculated for each count from the difference between the actual resolver value (solid line).
