Abstract
Without making the address control more complex than necessary, a memory can be effectively utilized by accessing a square memory area. According to a processor of the present invention connected to memory apparatus having a two-dimensional memory area comprised of rows and columns, the processor comprises registers for storing a start address, an end address, and a number of columns per row of a square area on the memory. The registers are used to generate access addresses for accessing the square area. The processor is provided with the address generation and control unit for outputting the generated access addresses. The address generation and control unit includes a modulo addressing control unit for generating the access addresses for cyclically accessing the square area. A square circulation mode information decides whether or not to access cyclically the square area. Based on a value of the square circulation mode information, whether or not to cyclically access the square area is decided.
