    摘要: A data processing apparatus includes a first memory which comprises a first input/output port and a second input/output port; a second memory which is connected to the first memory and comprises a third input/output port; and a controller for controlling the first and second memories to perform operations of: (a) writing data to the first memory through the first input/output port; (b) reading the data from the first memory through the second input/output port; (c) writing the data read out of the first memory to the second memory through the third input/output port; and (d) reading the data from the second memory through the third input/output port; wherein the operation (a) is performed at a first frequency and the operations (b), (c), (d) are each performed at a second frequency, wherein either: (i) the first frequency is different from the second frequency, or (ii) the first frequency is equal to the second frequency but in each of the operations (b), (c) and (d) the data is different in phase than in the operation (a).
