Abstract

Circuits, methods, and apparatus incorporate both a wireless physical interface and audio processing unit on a single integrated circuit. The wireless physical interface may include a receiver, transmitter, or a complete transceiver. The audio processing unit is typically in communication with both the wireless interface and one or more wired physical interfaces. The integrated circuit may be as simple as a wireless physical interface and audio processing unit, or it may include other circuits such as graphics processors, networking interfaces, memories, or other circuits.

Claims

1. An integrated circuit comprising:

a wireless receiver to receive a first wireless signal carrying first audio information from a first source and a second wireless signal carrying second audio information from a second source;

an audio processor coupled to the wireless transceiver to receive the first audio information and the second audio information from the wireless receiver and to blend the first audio information and the second audio information to generate first processed audio information; and

an output cell to provide the first processed audio information.

2. The integrated circuit of claim 1 wherein the wireless receiver demodulates the first wireless signal received from the first source and the second wireless signal received from the second source.

3. The integrated circuit of claim 2 wherein the first wireless signal is compliant with a wireless standard that is a short range RF standard.

4. The integrated circuit of claim 3 wherein the short range RF standard is one of the group consisting of IEEE 802.11a, IEEE 802.11b, IEEE 802.11g, and Bluetooth.

5. The integrated circuit of claim 1 wherein the audio processor also mixes the first audio information and the second audio information.

6. The integrated circuit of claim 1 wherein the output cell provides the first processed audio information to a speaker.

7. The integrated circuit of claim 1 wherein the output cell provides the first processed audio information to a storage unit.

8. The integrated circuit of claim 1 wherein the audio processor further performs one of the group consisting of mixing, overlaying, and synthesizing.

9. The integrated circuit of claim 1 further comprising:

an input cell to receive audio information; and

a wireless transmitter to receive second processed audio information and transmit the second processed audio information in the form of a third wireless signal,

wherein the audio processor is further coupled between the input cell and the wireless transmitter.

10. An integrated circuit comprising:

a wireless receiver to receive first audio information in the form of a first RF signal consistent with a wireless standard and to receive second audio information in the form of a second RF signal consistent with a wireless standard;

an audio processor coupled to the wireless transceiver to mix the first audio information and the second audio information; and

an output cell coupled to the audio processor to provide the mixed audio information.

11. The integrated circuit of claim 10 wherein the wireless receiver demodulates the first RF signal and the second RF signal.

12. The integrated circuit of claim 11 wherein the wireless standard is a short range RF standard.

13. The integrated circuit of claim 12 wherein the short range RF standard is one of the group consisting of IEEE 802.11a, IEEE 802.11b, IEEE 802.11g, and Bluetooth.

14. The integrated circuit of claim 10 wherein the audio processor further performs one of the group consisting of blending, overlaying, and synthesizing.

15. An integrated circuit comprising:

a wireless receiver to receive a first wireless signal carrying first audio information from a first source and a second wireless signal carrying second audio information from a second source;

an audio processor coupled to the wireless transceiver to receive the first audio information and the second audio information from the wireless receiver and to synthesize the first audio information and the second audio information to generate first synthesized audio information; and

an output cell to provide the first processed audio information.

16. The integrated circuit of claim 15 wherein the audio processor further performs one of the group consisting of mixing, overlaying, and blending.
