Latest Patents

One of Jimmy Yang's latest patents is titled "Complex-shaped video overlay using multi-bit row and column index registers." This innovation reduces the need for fetching color-key pixels from memory when displaying video pixels from a video-overlay window. The graphics system achieves this by dividing a frame buffer into multi-line, multi-pixel blocks arranged in block-rows and block-columns. The system utilizes primary and secondary row indicator bits, along with column indicator bits, to efficiently manage memory fetching. When the primary row indicator bit is cleared, all pixels in the block-row are fetched from the frame buffer memory. Conversely, when it is set, the secondary row indicator bit determines which column indicator bits to read. This method allows for the generation of dummy color-key pixels that match the color key, thereby reducing memory fetching and improving display efficiency.

Another notable patent by Yang is "Display rotation using a small line buffer and optimized memory access." This patent describes a method for rotating an un-rotated image by 90 degrees for display purposes. The frame buffer stores X pixels per line and Y lines, and pixels are read using a burst of B pixels. The line buffer, which stores a block of B*Y pixels, facilitates the rotation by logically dividing the frame buffer into blocks that are B pixels wide. The blocks are read from the bottom line to the top, with an increasing offset that re-orders the pixels for the rotated display order.
