US Patent 11275997 Weight loading in an array

Disclosed herein are techniques for obtain weights for neural network computations. In one embodiment, an integrated circuit may include memory configured to store a first weight and a second weight; a row of processing elements comprising a first processing element and a second processing element, the first processing element comprising a first weight register, the second processing element comprising a second weight register, both of the first weight register and the second weight register being controllable by a weight load signal; and a controller configured to: provide the first weight from the memory to the row of processing elements; set the weight load signal to enable the first weight to propagate through the row to reach the first processing element; and set the weight load signal to store the first weight at the first weight register and the flush value at the second weight register.
