Abstract

A method comprises obtaining a value from each of a plurality of memory devices. Each of the values is indicative of a characteristic of a portion of a communication channel. The method further comprises programming a communication device based at least in part on the characteristic.

Claims

1. A method, comprising:

obtaining a value from each of a plurality of memory devices, each of said values indicative of a characteristic of a portion of a communication channel; and

programming a communication device based at least in part on said characteristic.

2. The method of claim 1 further comprising determining an end-to-end characteristic of the entire communication channel.

3. The method of claim 2 wherein programming the communication device comprises programming the communication device based on the end-to-end characteristic.

4. The method of claim 2 further comprising providing the end-to-end characteristic to a memory device associated with the communication device.

5. The method of claim 2 wherein the end-to-end characteristic comprises a value indicative of a total length of the communication channel, or a plurality of values, each value being indicative of a length of a different portion of the communication channel.

6. The method of claim 2 wherein the end-to-end characteristic comprises a value indicative of insertion or reflection losses.

7. The method of claim 1 wherein obtaining the value is performed without user involvement.

8. The method of claim 1 wherein programming the communication device comprises programming a device selected from a group consisting of a transmitter and a receiver.

9. The method of claim 1 wherein each value is indicative of a length of the portion of the communication channel.

10. A system, comprising:

a communication device that couples to a communication channel; and

management logic coupled to said communication device;

wherein said management logic obtains from memory a value indicative of a characteristic of a portion of the communication channel and programs the communication device based, at least in part, on said characteristic.

11. The system of claim 10 wherein the management logic determines an end-to-end characteristic of the entire communication channel.

12. The system of claim 11 wherein the management logic programs the communication device based on the end-to-end characteristic.

13. The system of claim 11 wherein the management logic provides the end-to-end characteristic to a memory device associated with the communication device.

14. The system of claim 11 wherein the end-to-end characteristic comprises a plurality of values, each value being indicative of a length of a different portion of the communication channel.

15. The system of claim 11 wherein the end-to-end characteristic comprises a value indicative of a total length of the communication channel.

16. The system of claim 10 wherein each value is indicative of a length of the portion of the communication channel, or is indicative of an insertion or reflection loss.

17. The system of claim 10 wherein the management logic obtains the value and programs the communication device while an electrical device containing the communication device is in a pre-boot environment.

18. The system of claim 10 wherein the management logic obtains the value and programs the communication device without user involvement.

19. A system, comprising:

a communication device; and

a baseband controller coupled to said communication device;

wherein, while said system is in a pre-boot environment, said baseband controller receives a communication channel characteristic and stores said received communication channel characteristic.

20. The system of claim 19 further comprising control logic that uses said stored communication channel characteristic to program said communication device during initialization of said system.
