Jun 5, 2002

Appl. No.:

10/163541

Inventors:

Wallace C. Kou - Los Altos CA, US

Assignee:

Silicon Motion, Inc. - San Jose CA

International Classification:

G06F003/00

US Classification:

710 36, 710 5, 710 14, 710 33, 711200, 712405

Abstract:

An apparatus for a compact disk with an independent audio functionality is disclosed. The apparatus includes a logic core, an IDE controller, and a pass-through module, which are coupled to a micro-controller core. The logic core receives and sends signals to and from a system interface in response to the micro-controller core. The logic core disables sending signals to the system interface in response to the micro-controller core. The IDE controller core receives and sends signals to and from a CD drive interface in response to the micro-controller core. The IDE controller core also disables sending signals to the CD drive interface in response to the micro-controller core. The pass-through module is coupled to the system interface and to the CD drive interface. The pass-through module passes signals between the system interface and the CD drive interface when the computer is in power on mode.

International Classification:

G06K 7/06

US Classification:

235441, 235492, 710 16

Abstract:

An interface converting apparatus that converts signals between a Secure Digital (SD) card and a Memory Stick Pro (MS Pro). The apparatus comprises a SD memory card interface, a MS Pro memory card interface, an address decoder and a micro controller. The micro controller is able to convert a memory address from the MS Pro memory card interface into a memory address needed by the SD memory card interface and vice versa, and the address decoder can then be used to access the data via the SD memory card interface or the MS Pro memory card interface.

Inventors:

Wallace Kou - Los Altos CA, US
Yu-Wei Chyan - Hsinchu, TW

International Classification:

G11C 11/34

US Classification:

365185230

Abstract:

A memory system with two voltage sources comprises a controlling chip which includes a built-in DC/DC converter for transforming low voltage to high voltage, used for transforming 1.8/3.3 voltage to 3.3 voltage. This does not only prevent the phenomenon of voltage drifting but improves the stability of the system.

Assignee:

SILICONMOTION INC. - Jhubei City

International Classification:

H04N 5/76

US Classification:

348231900

Abstract:

A memory card with the function of video or audio data processing includes a card controller and a memory for storing encoded video/audio data. The card controller includes a card microprocessor, a buffer and a video/audio data processor. The card microprocessor controls internal and external data access. The buffer is for temporarily storing data during data processing. The video/audio data processor is adapted for coding raw data from an external host system or decoding coded data stored in the memory.

International Classification:

G09G 500

US Classification:

345 1

Abstract:

A method and apparatus for a display controller connected to a host computer and driving a plurality of displays, the displays being refreshed independently for optimizing the viewing quality of each display. The invention further provides a power controller for reducing power consumption when the display memory is not being updated by the host computer.

International Classification:

G06F 1576

US Classification:

345519

Abstract:

A single-chip video-graphics controller displays a color image stored in an external display memory simultaneously on two devices having different refresh and display requirements. The controller includes a first display processor which fetches the color image from the external memory and displays the image on a first device, such as a color CRT monitor or TV. The controller reduces the bandwidth of the fetched color image on-the-fly and stores a copy of the reduced bandwidth image in another part of the external display memory. A second display processor fetches the reduced bandwidth copy at a rate compatible with a second display device, such as a DSTN flat-panel device using dithering for color depth enhancement. The two display processes are independent of each other, controlled only by the refresh requirements of the two display devices. In a specific embodiment of the invention, the controller includes a clock control circuit which alternatively slows or stops clock signals which operate the first display processor and the bandwidth reduction function when the first display device is shut off and when the color image is not changing over time.
