  • Publication number: 20220398441
    Abstract: A semiconductor device executes the processing of a neural network. The memory MEM1 holds a plurality of pixel values and j compressed weighting factors. The decompressor DCMP restores the j compressed weighting factors to the uncompressed k (k?j) weighting factors. The DMA controller DMAC1 reads the j compressed weighting factors from the memory MEM1 and transfers them to the decompressor DCMP. The n (n>k) accumulators in the accumulator unit ACCU multiply a plurality of pixel values and k uncompressed weighting factor to accumulate and add the multiplication results to the time series. A switch circuit SW1 provided between the decompressor DCMP and the accumulator unit ACCU transfers the k uncompressed weighting factors restored by the decompressor DCMP to n accumulators based on the correspondence represented by the identifier.

  • Publication number: 20220340117
    Abstract: A method for controlling the operation of a hydraulic braking system of a vehicle and in particular a vehicle drivable using muscle power and/or—in particular additionally—using motor power, an electric bicycle, e-bike, pedelec, or the like. In the method, it is checked whether a discharge condition for discharging an accumulator of the braking system is met. If the discharge condition is met, initially a controllable inlet valve in a primary circuit of the braking system is set into a partially closed state over a predefined duty cycle, in particular of 10%, and/or for a predefined time span and then an outlet valve of the accumulator is opened for a predefined time span—continuously or in intervals—so that brake fluid is discharged from the accumulator via the outlet valve, the primary circuit, and the inlet valve into a reservoir of a master cylinder of the primary circuit.
