Patent Number Title Of Patent Date Issued
RE38108 Computer system with video display controller having power saving modes May 6, 2003
A computer system includes an operator input device, a central processing unit (CPU), and a display device, such as a liquid crystal display (LCD) or cathode ray tube (CRT) providing a visible image to the computer user as an output of computer activity. The computer system includes a vi
7639693 Method and/or apparatus distributing variable-sized data units to variable destinations December 29, 2009
A method or system or apparatus provides improved data handling. In one aspect, destination scheduling is performed by scheduling polling rather than scheduling data emissions. In particular aspects, a scheduler assigns a weight and sequence number to each destination and tracks a po
7333097 Display apparatus and method capable of rotating an image February 19, 2008
A system for translating a portrait-oriented software address to a portrait-oriented yet landscape-configured display address. Based on the orientation of a display device, an address translation system either passes the software address "as is" or translates the address to represent
6226016 Display apparatus and method capable of rotating an image by 180 degrees May 1, 2001
A central processing unit (310) in a display system carries pixel-value signals and software-address signals representing the locations of the pixels whose values the pixel-value signals represent. An address-translation circuit (420) converts those software addresses to logical addr
6204864 Apparatus and method having improved memory controller request handler March 20, 2001
A computer system includes one or more display devices, such as a cathode ray tube (CRT) or liquid crystal display (LCD) for providing a visible display to a user of the computer system. The computer system includes a video display controller (VDC) with a graphics generator. This VDC
6145033 Management of display FIFO requests for DRAM access wherein low priority requests are initiated November 7, 2000
A display FIFO module is used in a DRAM interface. A low priority request and high priority request are both issued when the FIFO must receive new data or FIFO underrun will occur. This is determined by comparing the FIFO data level against a predetermined high threshold value. After a
6119207 Low priority FIFO request assignment for DRAM access September 12, 2000
The present invention is directed to a display FIFO module for use in DRAM interface that includes a DRAM controller sequencer which prioritizes requests for DRAM access received from various modules, such as a CPU, a BitBLT engine module, and a half frame buffer logic module, etc. The
6088806 Apparatus and method with improved power-down mode July 11, 2000
A power-down circuit (72) in a lap-top computer (10) cooperates with a separate monitor circuit (80) in each of a plurality of modules (68, 74, 76) that a video-display-controller integrated circuit (36) includes. In response to various stimuli, decoding logic (78) in the power-down circ
5886689 Computer system with video display controller having power saving modes March 23, 1999
A computer system includes an operator input device, a central processing unit (CPU), and a display device, such as a liquid crystal display (LCD) or cathode ray tube (CRT) providing a visible image to the computer user as an output of computer activity. The computer system includes a vi
5872998 System using a primary bridge to recapture shared portion of a peripheral memory of a peripheral February 16, 1999
A system and method recaptures peripheral device dedicated memory for use by other system components such as the CPU. The system comprises a CPU, a preferred primary PCI bridge and at least one peripheral system. The peripheral system comprises a peripheral device, a peripheral memory
5767866 Computer system with efficient DRAM access June 16, 1998
A computer system includes one or more display devices, such as a cathode ray tube (CRT) or liquid crystal display (LCD) for providing a visible display to a user of the computer system. The computer system includes a video display controller (VDC) with a graphics generator. This VDC
5724063 Computer system with dual-panel LCD display March 3, 1998
A computer system includes a dual-panel monochrome or color liquid crystal display (LCD). A dynamic random access memory (DRAM) of the computer includes a defined virtual memory array representative of pixel locations of the dual-panel LCD. Pixel values are read from the virtual array of
5694141 Computer system with double simultaneous displays showing differing display images December 2, 1997
A computer system includes a pair of display devices, such as cathode ray tubes (CRT's) or liquid crystal displays (LCD's) for providing a visible display to a user of the computer system. The computer system includes a video display controller (VDC) providing for simultaneous display of
5673416 Memory request and control unit including a mechanism for issuing and removing requests for memo September 30, 1997
The present invention is directed to a display FIFO module for use in DRAM interface that includes a DRAM controller sequencer which prioritizes requests for DRAM access received from various modules, such as a CPU, a blit engine module, and a half frame buffer logic module, etc. The dis
