Abstract

A system, method and article of manufacture provide a user interface for a decoder of audio data in the MPEG 1 Layer III (MP3) format. A display control program that controls operation of a touch screen is initiated. The touch screen is coupled to a reconfigurable logic device capable of decoding MP3 audio. A plurality of icons are displayed on the touch screen. A user selects one of the icons by touching the icon on the touch screen. A periodic determination is made as to whether a user has touched the touch screen. If a touch is detected, a location of the touch is determined. The location of the touch is correlated with one of the icons. A macro associated with the icon touched is called. The macro is utilized for processing a command for controlling the reconfigurable logic device.

Claims

1. A method for providing a user interface for a decoder of audio data in the MPEG 1 Layer III (MP3) format, comprising the steps of:

(a) initiating a display control program for controlling operation of a touch screen, wherein the touch screen is coupled to a reconfigurable logic device capable of decoding MP3 audio;

(b) displaying a plurality of icons on the touch screen, wherein a user selects one of the icons by touching the icon on the touch screen, wherein each of the icons is associated with a macro;

(c) periodically determining whether a user has touched the touch screen;

(d) determining a location of the touch upon determining that the user has touched the touch screen;

(e) correlating the location of the touch with one of the icons; and

(f) calling a macro associated with the icon touched, wherein the macro is for processing a command for controlling the reconfigurable logic device.

2. A method as recited in claim 1, wherein the reconfigurable logic device includes at least one Field Programmable Gate Array (FPGA).

3. A method as recited in claim 1, wherein the display control program is implemented in the reconfigurable logic device.

4. A method as recited in claim 1, wherein the icons are positioned on bit boundary pixels for increasing speed.

5. A method as recited in claim 1, wherein the icons represent functions selected from a group consisting of:

play, pause, stop, skip track forward, skip track back, and change volume.

6. A method as recited in claim 1, wherein the display control program is called upon the reconfigurable logic device being configured to decode audio data in the MP3 format.

7. A computer program product for providing a user interface for a decoder of audio data in the MPEG 1 Layer III (MP3) format, comprising:

(a) computer code for initiating a display control program for controlling operation of a touch screen, wherein the touch screen is coupled to a reconfigurable logic device capable of decoding MP3 audio;

(b) computer code for displaying a plurality of icons on the touch screen, wherein a user selects one of the icons by touching the icon on the touch screen;

(c) computer code for periodically determining whether a user has touched the touch screen;

(d) computer code for determining a location of the touch upon determining that the user has touched the touch screen;

(e) computer code for correlating the location of the touch with one of the icons; and

(f) computer code for calling a macro associated with the icon touched, wherein the macro is for processing a command for controlling the reconfigurable logic device.

8. A computer program product as recited in claim 7, wherein the reconfigurable logic device includes at least one Field Programmable Gate Array (FPGA).

9. A computer program product as recited in claim 7, wherein the display control program is implemented in the reconfigurable logic device.

10. A computer program product as recited in claim 7, wherein the icons are positioned on bit boundary pixels for increasing speed.

11. A computer program product as recited in claim 7, wherein the icons represent functions selected from a group consisting of:

play, pause, stop, skip track forward, skip track back, and change volume.

12. A computer program product as recited in claim 7, wherein the display control program is called upon the reconfigurable logic device being configured to decode audio data in the MP3 format.

13. A system for providing a user interface for a decoder of audio data in the MPEG 1 Layer III (MP3) format, comprising:

(a) a reconfigurable logic device capable of decoding MP3 audio;

(b) a touch screen coupled to the reconfigurable logic device;

(c) logic for initiating a display control program for controlling operation of the touch screen;

(d) logic for displaying a plurality of icons on the touch screen, wherein a user selects one of the icons by touching the icon on the touch screen;

(e) logic for periodically determining whether a user has touched the touch screen;

(f) logic for determining a location of the touch upon determining that the user has touched the touch screen;

(g) logic for correlating the location of the touch with one of the icons; and

(h) logic for calling a macro associated with the icon touched, wherein the macro is for processing a command for controlling the reconfigurable logic device.

14. A system as recited in claim 13, wherein the reconfigurable logic device includes at least one Field Programmable Gate Array (FPGA).

15. A system as recited in claim 13, wherein the display control program is implemented in the reconfigurable logic device.

16. A system as recited in claim 13, wherein the icons are positioned on bit boundary pixels for increasing speed.

17. A system as recited in claim 13, wherein the icons represent functions selected from a group consisting of:

play, pause, stop, skip track forward, skip track back, and change volume.

18. A system as recited in claim 13, wherein the display control program is called upon the reconfigurable logic device being configured to decode audio data in the MP3 format.
