METHOD AND APPARATUS FOR DIRECT CONVOLUTION CALCULATION

systems and methods for efficient convolution based on matrix multiply and add (mma) are described. an example processor having a plurality of processing lanes is configured to perform convolution of a matrix of activation elements and a filter matrix in accordance with a configurable series of instructions including a plurality of mma instructions and shift instructions while reusing activation elements already loaded to the datapath or associated memory over a plurality of mma operations. associated methods are also described.
