  • Apparatus for efficiently accessing graphic data for rendering on a display
    Patent number: 5671401
    Abstract: An electronic logic and computer implemented apparatus and method for accessing graphic geometric data within a computer display system utilizing an SIMD environment. The present invention spreads the vertex data structure of geometric primitives across multiple memories allowing much higher bandwidth access into the data structure for greater performance. The present invention eliminates branches from the processing of triangle and quadrilateral primitives allowing full utilization of SIMD processors. The present invention utilizes an indirection circuit and software to control the order of coupling of these memory units to the inputs of specialized graphic processors. Therefore, the indirection mechanism allows a geometric data structure to be spread across multiple memories in a multi-memory/multi-bus environment with indirection across these multiple busses and memories.
