Patent number: 6337684Abstract: A high precision, memory efficient method for the compression of surface normals and the inverse method for the decompression of those compressed surface normals back into surface normals. The normals are first scaled to unit length in Cartesian coordinates. Then, each of the smallest two vector components of the unit length normal is stored along with an indicator of which of the three vector components is not stored plus the algebraic sign of that vector component. Decompression of the surface normal requires first converting the two stored vector components into floating-point values and then using the equation 1=x2+y2+z2 in order to obtain the non-stored vector component of the unit length normal.Type: GrantFiled: May 29, 1998Date of Patent: January 8, 2002Assignee: Hewlett-Packard CompanyInventors: Don W. Dyer, Kenneth W. Shrum, Noel D. Scott

Patent number: 6094200Abstract: An occlusion culling circuit for use in a graphics computer receives graphics primitives data including x and y coordinates for each pixel, a z depth value, and r, g, b, and a or index color data. For each group of primitives, the graphics computer scans the primitive and determines a volume which completely bounds the primitive. The z depth values for the pixels comprising the bounding volume are then compared by the occlusion culling circuit to the depths of the pixels in the already rendered primitives to determine whether any pixels in the incoming primitive are visible. If no pixels are visible, the occlusion culling circuit clears the result register and receives the next graphics primitive. If, on the other hand, one or more pixels is visible, the occlusion culling circuit completely renders the primitives bounded by the bounding volume.Type: GrantFiled: February 6, 1998Date of Patent: July 25, 2000Assignee: Hewlett-Packard CompanyInventors: Daniel M. Olsen, Noel D. Scott, Robert J. Casey

Patent number: 5949440Abstract: A graphics processor is disclosed having two processing units and two dual-port RAMs for passing data between the processing units. The hardware is configured to process two graphics primitives simultaneously in a first mode, and to use both processing units simultaneously to process a single primitive in a second mode. One of the dual-port RAMs may function as a FIFO buffer in the second mode. A method for processing graphics primitives is disclosed in which one processing unit generates a set of intermediate results for a first primitive and stores them in a first RAM, and then generates a set of intermediate results for a second primitive and stores them in a second RAM while another processing unit reads the first RAM and completes calculations for the first primitive. Afterwards, the second processing unit reads the second RAM and completes calculations for the second primitive.Type: GrantFiled: November 25, 1997Date of Patent: September 7, 1999Assignee: Hewlett Packard CompnayInventors: Alan S. Krech, Jr., Noel D. Scott

Patent number: 5940086Abstract: A system and associated method for dynamically allocating vertex data to a plurality of geometry accelerators in a computer graphics system based upon the relative current capability of the geometry accelerators to process the data. This efficient distribution of vertex data substantially reduces the amount of time individual geometry accelerators remain idle, thereby increasing both the efficiency of each geometry accelerator as well as the overall parallel processing of vertex data. This selective utilization of geometry accelerators thereby results in a significant increase in the throughput performance of the computer graphics system. A computer graphics system in accordance with the present invention comprises a plurality of geometry accelerators and a distributor connected through two unidirectional buses that transmit data in opposite directions. The geometry accelerators are connected, through appropriate interfacing hardware, directly to an input bus.Type: GrantFiled: January 10, 1997Date of Patent: August 17, 1999Assignee: Hewlett Packard CompanyInventors: Eric Rentschler, Alan S. Krech, Jr., Noel D. Scott

Patent number: 5856831Abstract: A clamping system is designed to clamp floating point values from a geometry accelerator in a computer graphics system. The clamping system includes a register configured to receive the floating point value from a connection from the geometry accelerator in the graphics system. Logic associated with the register is configured to determine when the value is less than or equal to a first threshold value (preferably, 0), greater than or equal to a second threshold value (preferably, 1), and between the first and second threshold values. An output mechanism is controlled by the logic. In the preferred embodiment, the output mechanism is a multiplexer interconnected with a tristate driver.Type: GrantFiled: June 12, 1996Date of Patent: January 5, 1999Assignee: Hewlett-Packard CompanyInventors: Noel D. Scott, John R. Pessetto

Patent number: 5664114Abstract: An enhanced performance queuing system that includes a FIFO queue in an electronic device, where the FIFO queue is controlled by a FIFO queue controller that also provides FIFO queue status relating to space available in the FIFO queue. A first device writes data to the FIFO queue in data chunks or in data item increments within a data chunk. FIFO queue status is requested only to determine if a data chunk sized space is free prior to writing to a data chunk space in the FIFO queue, rather than polling for FIFO queue status prior to each write operation. A second device reads data from the FIFO queue in data chunks or data item increments from within a data chunk. The first device begins writing to the FIFO queue prior to signaling the second device to begin reading, so that the second device can read from the FIFO queue without ever catching up with the first device thereby eliminating the need for requesting FIFO queue status to determine if data is available for reading.Type: GrantFiled: May 16, 1995Date of Patent: September 2, 1997Assignee: Hewlett-Packard CompanyInventors: Alan S. Krech, Jr., Noel D. Scott

Patent number: 5623527Abstract: Apparatus for determining an integer power of a floating point number includes a shift register, a register file having a partial product register and a binary power register, a multiplier coupled to the register file for performing floating point multiply operations and a state machine for controlling the shift register, the register file and the multiplier. The state machine controls loading of initial values into the shift register and into the partial product register and the binary power register. The state machine controls execution of an integer power routine in which a new partial product value is determined by multiplying the contents of the partial product register by the contents of the binary power register if the LSB of the shift register is a 1. The partial product value is left unchanged if the LSB of the shift register is a 0. A new binary power value is determined by multiplying the contents of the binary power register by itself.Type: GrantFiled: January 30, 1996Date of Patent: April 22, 1997Assignee: Hewlett-Packard CompanyInventor: Noel D.
