Latest Patents
Fetter holds a patent for a "High Speed Z-Buffer with Dynamic Random Access Memory." This invention provides apparatus and methods that are most advantageously used in conjunction with a computer display system incorporating the use of a Z-buffer. The Z-buffer is essential for three-dimensional hidden surface elimination. The patent describes a buffer memory that is sufficiently large to represent each display element (pixel) with a 16-bit Z value, corresponding to the Z-axis depth of the object at that pixel. The buffer comprises a plurality of dynamic random access memories (D-RAMs) that operate in two modes: Normal and Read-Modify-Write (RMW). The invention allows for efficient processing of graphics by utilizing a counter/pointer register to address values in the buffer, thereby enhancing the performance of graphics processors.
