Abstract
To provide a method of using a memory that can contribute to an efficient SIMD operation. The method of using the memory includes the steps of: supposing a predefined two dimensional memory space consisting of predefined virtual minimum two dimensional memory spacesarranged in longitudinal and transverse directions; and preassigning each address of the virtual minimum two dimensional memory spaceto an address in each of n physical memories determined in relation with the virtual minimum two dimensional memory space. At the time of reading the data, a reading address is designated in the virtual minimum two dimensional memory spaceand a data reading direction is designated as the transverse direction or longitudinal direction of data with reference to the designated reading address, whereby continuous data arranged in the transverse or longitudinal direction in the virtual minimum two dimensional memory spaceis read in accordance with the designated address and the designated direction from a corresponding address in each of the n physical memories.
