Abstract
A system includes global memory circuitry configured to store input tensors and output tensors. Row data paths are each connected to an output port of the memory circuitry. Column data paths are connected to an input port of the memory circuitry. Processing elements are arranged in rows and columns along the row data paths and column data paths, respectively. The processing elements include local memory circuitry configured to store multiple masks and processing circuitry. The processing circuitry is configured to receive portions of the input tensors from one of the row data paths; receive masks from the local memory circuitry; perform multiple tensor operations on a same received portion of an input tensors by applying a different retrieved mask for each tensor operation; and generate, using results of the multiple tensor operations, an output for a corresponding column data path.
