Abstract: A machine learning optimization circuit and a method thereof are provided. The method includes steps of: generating a local feature matrix from an extraction range in a feature tensor matrix, and the local feature matrix includes feature values of X columns, Y rows, and Z channels; partitioning W sub-feature matrices from the local feature matrix, and each of the W sub-feature matrices includes X×Y×Z/W feature values; simultaneously performing parallel dot product operations on the W sub-feature matrices by W×K parallel operation modules to generate W×K temporary feature matrices; and integrating the W×K temporary feature matrices into a local feature output matrix corresponding to the local feature matrix, and the local feature output matrix includes feature values of X columns, Y rows, and Z channels.

Abstract: An integrated apparatus of water-cooled motor and driver includes a motor housing and a driver housing. The motor housing includes a motor-housing inner wall, a motor-housing outer wall, an inlet, a heat-dissipation flow channel and an outlet. The motor-housing inner wall surrounds and receives a motor assembly. The motor-housing outer wall surrounds the motor-housing inner wall, and the exterior thereof has a first connecting surface. The inlet is disposed on the motor-housing outer wall. One end of the heat-dissipation flow channel is connected to the inlet, the end contacts and is received between the motor-housing inner wall and the motor-housing outer wall. The outlet is connected to the other end of the heat-dissipation flow channel and is disposed on the motor-housing outer wall. The driver housing receives a driver assembly, and the exterior thereof has a second connecting surface connected with and bonded to the first connecting surface.
