A matrix transformation device and method, and a data processing system are described herein. The device includes: a first shift unit configured to receive matrix data and perform a first cyclic shifton the matrix data to generate first data; a cache unit configured to write each row of data in the first data into the cache unit in an arrangement order different from an arrangement order of eachpiece of data in the row of data to store the first data as second data; and a second shift unit configured to read the second data from the cache unit and perform a second cyclic shift on the seconddata to generate transformed matrix data. 本文中描述了用于变换矩阵的装置和方法、数据处理系统。该装置包括：第一移位单元，被配置为接收矩阵数据，并且对矩阵数据进行第一循环移位，以生成第一数据；缓存单元，被配置为将第一数据中的每一行数据以与该行数据中的各个数据的不同排列的排列顺序来写入到缓存单元，以将第一数据存储为第二数据；以及第二移位单元，被配置为从缓存单元读取第二数据，并且对第二数据进行第二循环移位，以生成变换后的矩阵数据。
