Abstract

Applications such as web-browsers, email clients are currently available on high-end devices such as personal computers, workstations and laptops. The Internet has started to also become available on thin client devices such as touch panel displays, TVs, mobile phones and other handheld devices. The technology currently available for these thin client devices cannot easily utilize the technology from the high-end devices with respect to graphics due to limits on the memory and CPU power available. To overcome this problem, it is necessary to recognize that thin client devices have limited display and display update requirements, and hence, a carefully chosen set of features required by Internet related applications (e.g. browser, email client, instant messaging system) can be implemented in a graphics chip. In particular, a graphics chip can operate in unison with a processing device which sends necessary object information to the graphics chip to display. The processing device fetches the markup language data, parses the markup language data and creates a table of objects. The graphics chip reads the properties of these objects, such as text, image, buttons, text field objects etc., and displays them on the display devices with the use of a number of graphics engines for processing text, image and geometry objects.

Claims

1. A method for converting markup language data into display data comprising:

translating the markup language data into object entries within an object table, each object entry comprising a set of properties related to an item for display on a display device;

separating the object entries into a plurality of object types; and

processing the object entries of each of the object types with separate graphic engines to generate display data corresponding to the object entries.

2. A method according to claim 1, wherein the translating the markup language data into object entries within an object table comprises parsing the markup language data into one or more markup language tags and, for a plurality of the parsed markup language tags, inserting a set of properties related to an item for display corresponding to the particular parsed markup language tag into the object table.

3. A method according to claim 1, wherein the set of properties related to an item for display comprises the location, size and type of the item for display.

4. A method according to claim 3, wherein the set of properties related to an item for display further comprises at least one of type specific properties and a data pointer.

5. A method according to claim 1, wherein the plurality of object types comprises text, image and geometry types;

and

wherein the processing the object entries of each of the object types comprises processing object entries of the text type with a text graphic engine, processing object entries of the image type with an image graphic engine and processing object entries of the geometry type with a geometry graphic engine.

6. A graphic display system, arranged to be coupled to a display device, comprising:

an interface for receiving markup language data;

a markup language processor, coupled to the interface, for translating the received markup language data into object entries, each object entry comprising a set of properties related to an item for display on the display device;

a memory device, coupled to the markup language processor, for storing an object table that stores the object entries;

an object table processor, coupled to the memory device, for separating the object entries into a plurality of object types; and

a plurality of graphic engines, each coupled to the object table processor, each graphic engine for processing the object entries of a specific object type to generate display data corresponding to the object entries.

7. A graphic display system according to claim 6, wherein the markup language processor in order to translate the received markup language data operates to parse the markup language data into one or more markup language tags and, for a plurality of the parsed markup language tags, insert a set of properties related to an item for display corresponding to the particular parsed markup language tag into the object table.

8. A graphic display system according to claim 6, wherein the plurality of object types comprises text, image and geometry types;

and

wherein the plurality of graphic engines comprises a text graphic engine for processing object entries of the text type, an image graphic engine for processing object entries of the image type and a geometry graphic engine for processing object entries of the geometry type.

9. A graphic display system according to claim 6, wherein the markup language processor operates without the use of a standard operating system.

10. A graphics display system according to claim 6, wherein the interface and markup language processor are integrated together within a first apparatus and the memory device, object table processor and plurality of graphics engines are integrated within a second apparatus coupled to the first apparatus.

11. A graphics display system according to claim 10, wherein the first and second apparatus are physically adjacent to each other.

12. A graphics display system according to claim 10, wherein the first and second apparatus are coupled together via a network.

13. A graphics display system according to claim 6, wherein the interface, markup language processor, memory device, object table processor and plurality of graphics engines are integrated within a single apparatus.

14. A graphics display system according to claim 13, wherein the single apparatus is a processing device capable of running software algorithms;

and

wherein the markup language processor, object table processor and plurality of graphics engines are implemented within software algorithms.

15. A display component incorporating the graphic display system according to claim 6 and further comprising:

a display device for receiving the display data corresponding to the object entries and depicting graphically the properties of the object entries.

16. A processing apparatus, arranged to be coupled to a graphics engine apparatus including an object table, the processing device comprising:

an interface for receiving markup language data;

parsing logic for parsing the received markup language data into one or more markup language tags; and

processing logic that operates, for a plurality of the parsed markup language tags, to insert an object entry corresponding to the particular parsed markup language tag into the object table, each object entry comprising a set of properties related to an item for display on a display device.

17. A processing apparatus according to claim 16, wherein the set of properties related to an item for display comprises the location, size and type of the item for display.

18. A processing apparatus according to claim 17, wherein the type of the item comprises one of text, image and geometry types.

19. A processing apparatus according to claim 16, wherein the processing apparatus operates without the use of a standard operating system.

20. A graphics engine apparatus, arranged to be coupled to a processing apparatus and a display device, the graphics engine apparatus comprising:

a memory device, coupled to the processing apparatus, for receiving object entries from the processing apparatus and storing the object entries within an object table, each object entry comprising a set of properties related to an item for display on the display device;
