1. A system for vector memory array transposition, the system comprising: a vector memory to store a vector memory array; a block transposition accelerator coupled to the vector memory, the block transposition accelerator to read a vector of a block of data within the vector memory array and to write a transposition of the vector of the block of data to the vector memory; and an address controller coupled to the block transposition accelerator, the address controller to determine a vector access order, wherein the block transposition accelerator is configured to access the vector of the block of data within the vector memory array according to the vector access order.
