Abstract

An apparatus and a system, as well as a method and article, may operate to share an energy conduit, such as an antenna, between first data communicated according to a first formatting mechanism and second data communicated according to a second formatting mechanism according to a first priority assigned to the first data and a second priority assigned to the second data. The first formatting mechanism may be different from the second formatting mechanism.

Claims

1. A method for transmitting data over a shared energy conduit, including:

assigning priorities to data attempted to be communicated according to a first formatting mechanism and priorities to data attempted to be communicated according to a second formatting mechanism;

storing the prioritized data attempted to be communicated according to the first formatting mechanism and the prioritized data attempted to be communicated according to the second formatting mechanism into a queue;

determining, prior to transmission, which of the prioritized data attempted to be communicated according to the first formatting mechanism and the prioritized data attempted to be communicated according to the second formatting mechanism has the greatest priority within the queue;

transmitting the prioritized data having the greatest priority from the queue on the shared energy conduit that is configured to be shared between data attempted to be communicated according to the first formatting mechanism and data attempted to be communicated according to the second formatting mechanism; and

updating the assignment of priorities to data that has not been transmitted.

2. The method of claim 1, wherein the first formatting mechanism is selected from one of a communications standard, a communications protocol, a spread-spectrum communications technique, a data format, and a data type.

3. The method of claim 2, wherein the communications standard includes at least one of an Institute of Electrical and Electronics Engineers 802.11 standard and a Bluetooth System Specification.

4. The method of claim 1, wherein the priority assigned to data attempted to be communicated according to the first formatting mechanism is indicated by a priority tag attached to the data according to an Institute of Electrical and Electronics Engineers 802.1Q standard.

5. The method of claim 1, further including:

sharing the priorities assigned to data attempted to be communicated according to the first formatting mechanism and the priorities assigned to data attempted to be communicated according to the second formatting mechanism using a hardware bus.

6. The method of claim 1, further including:

storing the priorities assigned to data attempted to be communicated according to the first formatting mechanism and the priorities assigned to data attempted to be communicated according to the second formatting mechanism using a memory.

7. The method of claim 1, wherein the step of determining the prioritized data with greatest priority further includes:

using an arbitration scheme to determine the prioritized data with the greatest priority in the queue when it is determined that prioritized data attempted to be communicated according to the first formatting mechanism and the prioritized data attempted to be communicated according to the second formatting mechanism are substantially equal.

8. The method of claim 7, wherein the arbitration scheme used to determine the prioritized data with the greatest priority is selected from one of a round-robin technique, a credit-based technique, and a sliding window technique.

9. An article including a computer-readable medium having associated information, wherein the information, when accessed, causes a computer to perform steps of:

assigning priorities to data attempted to be communicated according to the first formatting mechanism and priorities to data attempted to be communicated according to the second formatting mechanism;

storing the prioritized data attempted to be communicated according to the first formatting mechanism and the prioritized data attempted to be communicated according to the second formatting mechanism into a queue;

determining, prior to transmission, which of the prioritized data attempted to be communicated according to the first formatting mechanism and the prioritized data attempted to be communicated according to the second formatting mechanism has the greatest priority within the queue;

transmitting the prioritized data having the greatest priority from the queue on a shared energy conduit shared between data to attempted be communicated according to the first formatting mechanism and data attempted to be communicated according to the second formatting mechanism; and

updating the assignment of priorities to data that has not been transmitted.

10. The article of claim 9, wherein the shared energy conduit is selected from one of an antenna, an infra-red transmitter, an infra-red receiver, a photo-emitter, a photo-receptor, and a charge-coupled device.

11. The article of claim 9, wherein the information, when accessed, further causes the computer to perform steps of:

determining that a priority assigned to data attempted to be communicated according to the second formatting mechanism is greater than a priority assigned to data attempted to be communicated according to the first formatting mechanism; and

selecting the shared energy conduit to communicate the data attempted to be communicated according to the second formatting mechanism.

12. The article of claim 9, wherein the first formatting mechanism is selected from one of a communications standard, a communications protocol, a spread-spectrum communications technique, a data format, and a data type.

13. The article of claim 9, wherein determining the prioritized data with the greatest priority further includes:

using an arbitration scheme to determine the prioritized data with the greatest priority when it is determined that the prioritized data attempted to be communicated according to the first formatting mechanism and the prioritized data attempted to be communicated according to the second formatting mechanism are substantially equal.

14. An apparatus, including:

an assignment module that is configured to assign priorities to data attempted to be communicated according to a first formatting mechanism and priorities to data attempted to be communicated according to a second formatting mechanism;

a memory that is configured to store the prioritized data attempted to be communicated according to the first formatting mechanism and the prioritized data attempted to be communicated according to the second formatting mechanism;

a determination module that is configured to determine, prior to transmission, which of the prioritized data attempted to be communicated according to the first formatting mechanism and the prioritized data attempted to be communicated according to the second formatting mechanism has a greatest priority within the memory;

a shared energy conduit that is configured to be shared between data attempted to be communicated according to the first formatting mechanism and data attempted to be communicated according to the second formatting mechanism; and

a transmitter that is coupled to the shared energy conduit, and that is configured to transmit the prioritized data having the greatest priority from the memory on the shared energy conduit, wherein the assignment module is further configured to update the assigned priorities to data that has not been transmitted.

15. The apparatus of claim 14, further including:

a steering mechanism to direct the prioritized data with the greatest priority to be communicated through space via the shared energy conduit.

16. The apparatus of claim 14, wherein the first formatting mechanism is selected from one of a communications standard, a communications protocol, a spread-spectrum communications technique, a data format, and a data type.

17. The apparatus of claim 14, wherein the priority assigned to data attempted to be communicated according to the first formatting mechanism is indicated by a priority tag attached to the data according to an Institute of Electrical and Electronics Engineers 802.1Q standard.

18. A system, including:

an assignment module assigning priorities to data attempted to be communicated according to a first formatting mechanism and priorities to data attempted to be communicated according to a second formatting mechanism;

a memory storing the prioritized data attempted to be communicated according to the first formatting mechanism and the prioritized data attempted to be communicated according to the second formatting mechanism;

a determination module determining, prior to transmission, which of the prioritized data attempted to be communicated according to the first formatting mechanism and the prioritized data attempted Lo be communicated according to the second formatting mechanism has the greatest priority within the memory; and

a shared energy conduit transmitting the prioritized data having the greatest priority from the queue, wherein the shared energy conduit is shared between data attempted to be communicated according to the first formatting mechanism and data attempted to be communicated according to the second formatting mechanism, and wherein the assignment module updates the assigned priorities to data that has not been transmitted.

19. The system of claim 18, further including:

a hardware bus to share the data attempted to be communicated according to the first formatting mechanism and the data attempted to be communicated according to the second formatting mechanism.

20. The system of claim 18, further including:

a transceiver to selectively couple the data attempted to be communicated according to the first formatting mechanism and the data attempted to be communicated according to the second formatting mechanism to the shared energy conduit.

21. The system of claim 18, wherein the determination module re-determines which of the prioritized data attempted to be communicated according to the first formatting mechanism and the prioritized data attempted to be communicated according to the second formatting mechanism has the greatest priority currently within the memory after data transmission via the shared energy conduit has begun.
