  • Patent number: 4476522
    Abstract: A peripheral processing controller controls time-shared access to a memory by specialized peripheral devices. The specialized peripheral devices process data independently of a central processor that simply supervises the system. The peripheral processing controller uses predetermined modes of memory space allocation for the various peripheral devices. A memory address register in the controller is assigned to each peripheral device. In addition, each MAR has one or more predefined modes of memory space allocation and, when active, controls memory access for its assigned peripheral device. The modes also define the size of the block of space allocated and whether memory access scrolls through various blocks of space or jumps between blocks of space. The controller also detects when a peripheral device has consumed all the space in a block.

  • Patent number: 4454575
    Abstract: A document distribution terminal can be required to process large volumes of data. To do this rapidly and efficiently, the terminal herein is organized to process all of the data in specialized peripheral devices. A supervising central processing unit (CPU) controls the terminal but does not perform any data processing. The functions of entering data, scanning documents, encrypting data, compressing data, transceiving data, decompressing data, decrypting data and printing data are all performed in parallel by specialized devices working directly with a memory. A peripheral processing controller is initialized by the CPU. The controller then controls time-shared access to the memory by the specialized devices, such as devices used for processing data representing facsimile images.

  • Patent number: 4342052
    Abstract: The apparatus shown herein controls a facsimile system to reduce four source documents and print all four reduced copies on a single copy page. The facsimile system prints one of the source documents in each quadrant of the copy document. The images of the source documents are reduced in the horizontal dimension by discarding every other picture element in the scan image. The images are reduced in the vertical dimension by increasing the scanner speed so that the size of the picture element in the vertical dimension is doubled. At the receiver, two scanned and reduced images will be printed on the left-hand half of the copy document. Subsequently, two additional scanned and reduced images are printed on the right-hand half of the copy document. When printing the right-hand half of the copy document, the printer must be referenced to start printing at the horizontal mid-page of the copy document rather than the left-hand edge of the copy document.
