    • A parallel computer of this invention includes a plurality of memory elements and a plurality of processing elements and each of the processing elements is connected to logically adjacent memory elements. For example, the processing elements which corresponds to a logical position (i, j) is connected to the memory elements which correspond to a plurality of logical positions (i, j), (i, jnull1), (inull1, j) and (inull1, jnull1). It is preferable if each of the memory elements can be accessed from the exterior. According to this invention, efficient memory access can be made and the parallel processing can be performed at high speed without increasing the hardware amount and making the control operation complicated. Further, the operation speed of the image processing can be enhanced by constructing an image memory by use of a plurality of memory elements and causing the processing element to effect the image processing in a distributed and cooperative manner.
    • 本发明的并行计算机包括多个存储器元件和多个处理元件,并且每个处理元件连接到逻辑上相邻的存储元件。 例如,对应于逻辑位置(i,j)的处理元件连接到与多个逻辑位置(i,j),(i,j + 1),(i + 1, j)和(i + 1,j + 1)。 优选地,可以从外部访问每个存储元件。 根据本发明,可以进行有效的存储器访问,并且可以高速执行并行处理,而不增加硬件量并使控制操作变得复杂。 此外,可以通过使用多个存储元件构造图像存储器并且使处理元件以分布和协作的方式实现图像处理,来增强图像处理的操作速度。
