摘要： A data processing system is provided that includes a plurality of processors each including a circuit for providing a busy signal. The system also includes a plurality of registers for storing data wherein each register is dedicated to a selected processor or a selected set of processors. A control circuit is provided for receiving the busy signals and prohibiting storage from an external device to the registers dedicated a processor when that processor provides a busy signal.

摘要： A graphics processor including an interface 30 for providing triangle primitives representing a graphics image includes a triangle interpolator 310 coupled to the interface for interpolating a triangle primitive and serially computing multiple line primitives from the triangle primitive. A line renderer 320 coupled to the receives a line primitive from the triangle interpolator and provides pixels representing the line primitive while the triangle interpolator is computing another line primitive.

摘要： In a system and process for picking three dimensional objects from images depicted on a video display the displayed objects are selectively rerendered. During such rerendering the object pixels are compared in depth to the data in a Z buffer 9 for determining visibility. The number and size of the objects subject to rerendering by the rasterization processor 2 is constrained by using the front end graphics processor 1 to define object extents and by rerendering only extents which have been clipped to the boundaries of the pick window. The rerendering operation does not alter the three dimensional graphics image stored in and repetitively scanned from the frame buffer 3. Selection between multiple objects within the pick window can include a weighted comparison using a pick plane memory 20 to store visibility data by object.
