Latest Patents

Leon Sigal holds a patent for a "Polygon span interpolator with main memory Z buffer." This invention is a scan converter that incorporates a polygon span interpolator with main memory Z buffering. The span interpolator is initiated by instructions from a central processing unit (CPU). Once initiated, it interpolates input color and Z values in parallel. The design allows the span interpolator to operate independently of the CPU's clock states, enabling the CPU to process other data simultaneously. Additionally, the Z buffer shares main memory with the CPU, allowing for more efficient data handling. This innovation significantly improves data transfer efficiencies by eliminating cache penalties present in prior art software scan converters.
