Latest Patents

One of his latest patents is focused on low-power and low-latency distortion correction for image processors. This invention incorporates a distortion correction (DC) sub-system designed to quickly correct skewed images. The DC sub-system includes a buffer, a processor, and a sparse matrix table (SMT). The buffer is sized according to the amount of distortion in an input image, allowing for efficient processing. Input image pixels from an input frame are buffered, while other pixels from the same frame overwrite the buffered pixels, reducing latency. The SMT is dynamically configurable, providing mapping values for output pixels to input pixels. The processor implements combinational logic, including multipliers, lookup tables, and adders, to interpolate flow control parameters, pixel coordinate values, and pixel intensity values. The distortion correction values are then streamed to a display or passed to a subsequent image processing block for further processing.

Another significant patent is for an energy-efficient processing device. This microcoded processor utilizes microinstructions to reduce power consumption by employing low power consumption registers to store the most recently retrieved data from a high power consumption control store. The control store, in combination with an indirect register file, provides the necessary micro-orders for the operation of the microcoded processor without extending the size of the microinstruction. Additionally, a microcode-driven single clock cycle control turns off circuitry when not needed, enhancing energy efficiency.
