Abstract
The present disclosure is directed to systems and methods for decomposing systolic array circuitry to provide a plurality of N×N systolic sub-array circuits, apportioning a first tensor or array into a plurality of N×M first input arrays, and apportioning a second tensor or array into a plurality of M×N second input arrays. Systolic array control circuitry transfers corresponding ones of the first input arrays and second input arrays to a respective one of the plurality of N×N systolic sub-array circuits. As the elements included in the first input array and the elements included in the second input array are transferred to the systolic sub-array, the systolic sub-array performs one or more mathematical operations using the first and the second input arrays. The systems and methods beneficially improve the usage of the systolic array circuitry thereby advantageously reducing the number of clock cycles needed to perform a given number of calculations.
