    • 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.
    • 在不使地址控制更复杂的情况下,可以通过访问方形存储区域来有效地利用存储器。 根据连接到具有由行和列组成的二维存储区域的存储装置的本发明的处理器,处理器包括用于存储起始地址,结束地址和每行平方面的列数量的寄存器 在记忆中 寄存器用于生成访问方形区域的访问地址。 处理器设置有用于输出生成的访问地址的地址生成和控制单元。 地址生成和控制单元包括模寻址控制单元,用于生成用于循环访问正方形区域的访问地址。 方形循环模式信息决定是否循环访问正方形区域。 基于平方循环模式信息的值,决定是否循环访问正方形区域。
