Latest Patents

One of Takayanagi's latest patents is a device for controlling data transfer between chips via a bus. This invention involves a draw control chip and video chips V1-V4, which are interconnected by a 64-bit data bus, a 4-bit program signal line, and a 1-bit ready signal line. The video chip V1 includes various components such as a decoder, program buffer address register, sequencer, and address control unit. This system allows for efficient data transfer from the control chip to multiple video chips in a single operation. The 64-bit data bus can be segmented, enabling smaller data segments to be processed simultaneously by the video chips. Additionally, the video chips can communicate directly with each other without needing to access the control chip.

Another significant patent by Takayanagi is a method and system for drawing narrow lines on a computer display. This innovation allows for the rapid drawing of straight lines and circular arcs of width 1 on a raster scan graphic display. The method determines whether specific points are between defined outlines, allowing for precise plotting of pixels. This technique enhances the efficiency and accuracy of graphic rendering on computer displays.
