    • An orthogonal transformation processor has a first one-dimensional orthogonal transformation calculator for calculating a one-dimensional orthogonal transformation; a memory device for temporarily storing an output of the first one-dimensional orthogonal transformation calculator; a second one-dimensional orthogonal transformation calculator for calculating a one-dimensional orthogonal transformation and inputting an output of the memory device thereto; and an address generator for designating an address of the memory device and replacing row and column addresses with each other in accordance with a switching operation of writing and reading operations of the memory device. Instead of this address generator, the orthogonal transformation processor may have an address generator for designating an address of the memory device and replacing row and column addresses with each other i n accordance with calculating operations of the first and second one-dimensional orthogonal transformation calculators. The orthogonal transformation processor may further have a reading-writing control section for reading one data of the memory device and writing new results calculated by the first one-dimensional orthogonal transformation calculator to the same address after the data reading operation.
    • 正交变换处理器具有用于计算一维正交变换的第一一维正交变换计算器, 用于临时存储第一一维正交变换计算器的输出的存储装置; 第二一维正交变换计算器,用于计算一维正交变换并向其输入存储器件的输出; 以及地址发生器,用于根据存储器件的写入和读取操作的切换操作指定存储器件的地址并且相互替换行和列地址。 代替该地址生成器,正交变换处理器可以具有用于指定存储器件的地址的地址发生器,并且根据第一和第二一维正交变换计算器的计算操作彼此替换行和列地址。 正交变换处理器还可以具有读取写入控制部分,用于在数据读取操作之后读取存储器件的一个数据并将由第一个一维正交变换计算器计算出的新结果写入相同的地址。
