  • Method and apparatus for managing concurrent access to multiple memories
    Patent number: 5511154
    Abstract: A memory apparatus includes a circuit for receiving and serially storing a plurality of instructions and a plurality of buffer memories each including a buffer controller for regulating access to that buffer. Also included is a circuit, connected to each buffer controller and the receiving circuit, for accessing one or more of said buffers in response to a first serially stored instruction while, in response to at least one other serially stored instruction, concurrently accessing at least one remaining buffer.
    Type: Grant

  • High performance triangle interpolator
    Patent number: 5457775
    Abstract: A graphics processor including an interface for providing triangle primitives representing a graphics image, a triangle interpolator coupled to the interface for interpolating a triangle primitive and serially computing multiple line primitives from the triangle primitive, a line renderer coupled to the triangle interpolator for receiving a line primitive from the triangle interpolator and for providing pixels representing the line primitive while the triangle interpolator is computing another line primitive.
    Type: Grant
    Filed: September 15, 1993
    Date of Patent: October 10, 1995
    Assignee: International Business Machines Corporation
    Inventors: Lee E. Johnson, Jr., Daryl J. Kokoszka, Steven P. Larky, Paolo Sidoli
  • High performance rasterization engine
    Patent number: 5452412
    Abstract: A graphics processor including an interface for providing triangle primitives and line primitives representing a graphical image, a line drawer for receiving line primitives and for rendering the line primitives, and a triangle interpolator for receiving the triangle primitives from the interface and for providing line primitives therefrom to the line drawer, wherein the interface includes a register for storing graphics image line primitives and for selectively providing the stored line primitives to the line drawer.

  • Method and apparatus for rendering lines
    Patent number: 5420972
    Abstract: A bitblt and line draw parameter calculator for preprocessing address information for a bitblt and line draw sequencer. The sequencer computes individual pixel addresses, controls color interpolation pacing and communicates with the memory hypervisor. By partitioning memory addressing into two tasks a first line or bitblt need only be partially processed prior to starting processing on a second line or bitblt.

  • I/O register protection circuit
    Patent number: 5339394
    Abstract: 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.
