Abstract: A first location and a last location of the required part of a first piece of picture information displayed at a display part are specified by cursors. Cleared data is transferred to a picture element memory where said picture information is stored for removing unnecessary picture information. The extracted necessary picture information is recorded in a magnetic tape device. Only the necessary part of a second piece of picture information is extracted in a similar manner and is recorded in the magnetic tape device. A logic sum of a title input from the keyboard and said first piece of picture information is obtained for each scanning line to provide a first synthesized picture. A logic sum of the first synthesized picture and said second piece of picture information is obtained for each line to provide a second synthesized picture.

Abstract: In a parallel data processing system architecture capable of processing in parallel a plurality of data elements from a linear vector stored in a memory module array having in number a power-of-two memory modules, a high degree of conflict-free access to the stored linear vector data elements is achieved through skewed storage wherein a skewing occurs at every Mth address and a further skewing at every M.sup.2 address wherein M (a power-of-two) is equal to the number of memory modules. The data elements are fetched through a connection network for processing in a processor array having in number a power-of-two processors.
