Abstract
An approach is described for a method, product, and apparatus for a machine learning process using weight sharing within a systolic array having reduced memory bandwidth. According to some embodiments, this approach includes providing a systolic array that includes processing elements which each have some number of storage elements for storing weights. For example, the weights can be reused for different data sets by identifying/capturing a current state of the storage elements, generating a plan to transition to a target state of those storage elements, and application of the transition plan such that weights that are already stored in those storage elements can be reused and/or relocate. This lowers the bandwidth requirements for weight memory by allowing weights that have previously been read into the systolic array to be reused.
