  • Method for combining vector-quantization decoding with color transform or halftoning or both
    Patent number: 6915019
    Abstract: A method of decompressing image data, includes reception of a VQ encoded image. The received image is decoded. Output image color space processing is performed in combination with the decoding as one process. Output image color space processing may include color transformation, half-toning or both. The resulting output image has been both decoded and transformed in color space.

  • Data bus protocol for high speed chip to chip data transfer
    Patent number: 5551052
    Abstract: A protocol for communication through a bus controller to control data transfers between a host processing platform and the data bus of a bit map printer. This protocol is optimized for a data bus which connects a number of ASIC accelerator cards in addition to the printer, disk controller, bus controller and other typical system cards. The basic data transfer cycle transfers eight data words on the bus between ASIC's, I/O devices, printer and any other devices.
