  • Patent number: 12050888
    Abstract: An in-memory computing method and apparatus, adapted for a processor to perform MAC operations on a memory, are provided. In the method, a format of binary data of weights is transformed from a floating-point format into a quantized format by truncating at least a portion of fraction bits of the binary data and calculating complements of remaining bits, and programming the transformed binary data into cells of the memory. A tuning procedure is performed by iteratively inputting binary data of input signals into the memory, integrating outputs of the memory, and adjusting the weights programmed to the cells based on the integrated outputs. The binary data of the weights is reshaped based on a probability of reducing bits with a value of one in the binary data of each weight. The tuning procedure is repeated until an end condition is met.

    Abstract: A centrifugal fan type cooling module includes a centrifugal fan and a radiator. The centrifugal fan provides a fan rotor with fan blades and an axial shaft and a fan stator set with an axial core, an upper cover and a frame. The fan blades extend straight forward radially with the outer end of each fan blade has an enlarged curve end part and the rest part of the respective fan blade has a width shorter than the axial shaft. The frame encloses and fits with the top of the radiator and the axial shaft is rotationally joined to the axial core such that a hollow space is formed between the radiator and the fan rotor. Heat from an electronic component is transmited to the radiator and removed outward quickly in all directions by way of upward suction force of the centrifugal fan instead of contacting other electronic members directly.
