  • Integrated circuit with unified memory system and dual bus architecture
    Patent number: 6247084
    Abstract: A unified memory system includes a processor, a memory controller, a plurality of bus transactor circuits and a shared memory port. A processor bus is coupled between the processor and the memory controller. A first multiple-bit, bidirectional system bus is coupled between the shared memory port, the memory controller and the plurality of bus transactor circuits. A second multiple-bit, bidirectional system bus is coupled between the memory controller and the plurality of bus transactor circuits.
    Type: Grant

    Inventors: George Apostol, Jr., Peter R. Baran, Roderick J. McInnis
  • Projected image linewidth correction apparatus and method
    Patent number: 5111513
    Abstract: An apparatus for correcting deviations in image linewidth in a image projection system having a laser and a liquid crystal cell wherein images are made on the liquid crystal cell by impinging the laser on said cell. The apparatus also has apparatus for creating a test image having a plurality of lines of specific width on a liquid crystal cell and calculating the difference between the linewidth of the plurality of lines of said test image as created and as expected. Furthermore, apparatus are provided for modifying the period of the laser light based on said differences in linewidth between the plurality of lines (as created and as expected) to correct deviations in image linewidth, whereby deviations in image linewidth are substantially eliminated.
