A data processing method and apparatus are described. The data processing apparatus obtains an input tensor corresponding to input data. The data processing apparatus determines Mfirst-type tensor blocks and Msecond-type tensor blocks. P processing units in the data processing apparatus process the M tensor blocks concurrently. In a first time period, all of the tensor blocks that are processed concurrently by the P processing units are first-type tensor blocks. In a second time period, all of the tensor blocks that are processed concurrently by the P processing units are second-type tensor blocks.

The present disclosure provides a displacement detection circuit of a maglev rotor system and a displacement self-sensing system thereof. The displacement detection circuit comprises a current sampling circuit () configured to collect a current flowing through a corresponding coil (); coils (), which are coils () distributed in series in the maglev rotor system; Hall sensors (), the Hall sensors () being arranged in an upper auxiliary air gap () and a lower auxiliary air gap () of the maglev rotor system, and sensing surfaces of the Hall sensors () being perpendicular to magnetic field directions in the corresponding auxiliary air gaps (); a Hall signal processing circuit () connected to the Hall sensors () and configured to differentiate a Hall sensing signal corresponding to the upper auxiliary air gap () and a Hall sensing signal corresponding to the lower auxiliary air gap (); and a displacement signal resolving circuit () connected to the current sampling circuit () and the Hall signal processing circuit () respectively and configured to acquire a displacement of a rotor in the maglev rotor system according to the current and a differentiation result. By using the detection circuit and the displacement self-sensing system thereof, the axial size of the rotor is reduced, such that detection and control are coplanar, and high precision and simple design are realized.
