ABSTRACT:
A data processing apparatus generates a memory address corresponding to a first memory, and interpolates data read out from the first memory. The data processing apparatus selects a part of the memory address, checks if the first memory stores data corresponding to the selected part of the memory address, and transfers the data, for which it is determined that the first memory does not store the data, and which corresponds to the part of the memory address, from a second memory to the first memory. The data processing apparatus determines to change a part to be selected of the memory address based on the checking result indicating that the first memory does not store the data corresponding to the selected part of the memory address, and changes the part of the memory address corresponding to the characteristics of the memory address.
