Abstract
Techniques to perform transpose operations in a crossbar circuit may include receiving a set of write transactions to write a data array to a target memory, and determining that the set of write transactions is for a transpose write. Write data for each of the write transactions can be stored diagonally in a transpose memory of the crossbar circuit. Each row of data in the transpose memory can be rotated, and rotated data from each row of the transpose memory can be provided to a corresponding output port of the crossbar circuit to write to the target memory.
