Abstract

A computing module includes an interface to asynchronously, serially exchange parallel system bus data with one or more other modules of a computer system that includes the computing module. The computing module can asynchronously, serially transfer first parallel bus data to another module of the computer system, and can asynchronously, serially receive second parallel bus data from another module of the computer system.

Claims

1. A method comprising:

asynchronously, serially transferring first serial data, corresponding to first parallel bus data, from a first module to a second module via a serial link without using handshaking; and

asynchronously, serially transferring second serial data, corresponding to second parallel bus data, from the second module to the first module via the serial link without using handshaking.

2. The method as recited in claim 1, wherein the first module comprises a processor module including a CPU and memory, and wherein the second module comprises a peripheral device.

3. The method as recited in claim 2, wherein the peripheral device comprises a hard drive.

4. The method as recited in claim 1, wherein the first module is separated from the second module by a distance of at least a meter.

5. The method as recited in claim 1, wherein the first module and the second module each comprises a portable computing device.

6. The method as recited in claim 1, wherein the first module comprises one of:

a disk drive, a keyboard, a mouse, a monitor, a printer, an Internet connection, a wireless accessory, or a storage module.

21. The method as recited in claim 1, further comprising:

generating a clock signal, for use by the first module, using the second serial data.

7. A method comprising:

asynchronously, serially transferring first serial data, corresponding to first parallel bus data, from a first module to a second module using a serial link;

asynchronously, serially receiving second serial data, corresponding to second parallel bus data, from the second module using the serial link; and

generating a first clock signal, for use by the first module, using the second serial data.

8. The method as recited in claim 7, wherein the asynchronously, serially transferring the first serial data comprises asynchronously, serially transferring the first serial data without requiring handshaking.

9. The method as recited in claim 7, wherein the first module is separated from the second module by a distance of at least several meters.

10. The method as recited in claim 7, wherein the first module and the second module each comprises a portable computing device.

11. The method as recited in claim 7, wherein the second module comprises one of:

a disk drive, a keyboard, a mouse, a monitor, a printer, an Internet connection, a wireless accessory, or a storage module.

12. The method as recited in claim 7, wherein the first module comprises a processor module including a CPU and memory, and wherein the second module comprises a peripheral device.

13. The method as recited in claim 7, wherein the first module comprises a hard drive.

14. The method as recited in claim 7, wherein the first module comprises a memory device.

22. The method as recited in claim 7, further comprising:

generating a second clock signal, for use by the second module, using the first serial data.

15. A computing module comprising:

a processor;

a parallel bus; and

a first interface coupled to a serial communications link and configured to asynchronously, serially exchange serial data corresponding to parallel bus data received from the parallel bus, via the serial communications link, with an additional module of a computer system that includes the computing module, the additional module including a second interface coupled to the serial communications link.

16. The computing module as recited in claim 15, wherein the first interface comprises a bridge.

17. The computing module as recited in claim 15, wherein the first interface is further configured to asynchronously, serially exchange the parallel bus data without requiring handshaking.

18. The computing module as recited in claim 15, further comprising:

a device configured to generate a clock signal from serial data received from the additional module via the serial communications link.

19. The computing module as recited in claim 15, wherein the computing module is separated from the additional module of the computer system by a distance of at least a meter.

20. The computing module as recited in claim 15, wherein the additional module comprises one or more of:

a disk drive, a keyboard, a mouse, a monitor, a printer, an Internet connection, a wireless accessory, or a storage module.
