US Patent 10884707 Transpose operations using processing element array

Provided are systems and methods for transposing a tensor using processing element array operations. In some cases, it may be necessary to transpose elements of a tensor to perform a matrix operation. The tensor may be decomposed into blocks of data elements having dimensions consistent with the dimensions of a systolic array. An identity multiplication may be performed on each block of data elements loaded into a systolic array and the multiplication products summed in column partitions of a results buffer. The data elements in the column partitions of results buffer can then be mapped to row partitions of a buffer memory for further processing.
