Abstract

A device and method for accelerating functioning of a software application having multi-layer, high overhead protocols, wherein the device has a first processor operating a software application having a multi-layer protocol; a second processor configured to operate at least one layer of the multi-layer protocol; and a memory accessible to each of the processor and the second processor.

Claims

1. A mobile device comprising:

a first processor configured to operate a software application having a multi-layer protocol that may be partitioned into more complex layers and less complex layers, wherein the first processor is configured to operate the less complex layers;

a second processor configured to process voice data when the second processor is operating a voice service option, configured to operate one of the more complex layers for the benefit of the first processor according to a command received from the first processor when the second processor is not operating the voice service option, and configured to provide a result of the operation of one of the more complex layers to the first processor; and

a memory accessible to each of the first processor and the second processor for passing commands and data between the first processor and the second processor to permit the second processor to operate the one of the more complex layers for the benefit of the first processor.

2. The mobile device of claim 1 wherein the first processor operates a multi-layer security protocol.

3. The mobile device of claim 1 wherein the second processor is configured to operate a mathematical algorithm layer of the multi-layer protocol.

4. The mobile device of claim 1 wherein the second processor further comprises a digital signal processor.

5. The mobile device of claim 4 wherein the digital signal processor is further configured to operate a modular math function.

6. The mobile device of claim 5 wherein the digital signal processor is further configured to operate a modular math function comprising an exponentiation function.

7. A circuit for a mobile device, the circuit comprising:

a first processor configured to operate a software application having a multi-layer protocol that may be partitioned into more complex layers and less complex layers, wherein the first processor is configured to operate the less complex layers;

a second processor configured to process voice data when the second processor is operating a voice service option, configured to operate one of the more complex layers for the benefit of the first processor according to a command received from the first processor when the second processor is not operating the voice service option, and configured to provide a result of the operation of one of the more complex layers to the first processor; and

a memory accessible to each of the first processor and the second processor for passing commands and data between the first processor and the second processor to permit the second processor to operate the one of the more complex layers for the benefit of the first processor.

8. The circuit of claim 7 wherein the first processor operates a multi-layer security protocol.

9. The circuit of claim 7 wherein the second processor is configured to operate a mathematical algorithm layer of the multi-layer protocol.

10. The circuit of claim 7 wherein the second processor further comprises a digital signal processor.

11. The circuit of claim 10 wherein the digital signal processor is further configured to operate a modular math function.

12. The circuit of claim 11 wherein the digital signal processor is further configured to operate a modular math function comprising an exponentiation function.

13. A mobile device, comprising:

first means for operating a software application having a multi-layer protocol that may be partitioned into more complex layers and less complex layers, and for operating the less complex layers;

second means for processing voice data when the second means is operating a voice service option, for operating one of the more complex layers for the benefit of the first means according to a command received from the first means when the second means is not operating the voice service option, and for providing a result of the operation of one of the more complex layers to the first means; and

third means for passing commands and data between the first means and the second means to permit the second means to operate the one of the more complex layers for the benefit of the first means.

14. A non-transitory computer-readable medium including program code stored thereon, comprising:

program code to cause a first processor to operate a software application having a multi-layer protocol that may be partitioned into more complex layers and less complex layers, wherein the first processor is configured to operate the less complex layers;

program code to cause a second processor to process voice data when the second processor is operating a voice service option, to operate one of the more complex layers for the benefit of the first processor according to a command received from the first processor when the second processor is not operating the voice service option, and to provide a result of the operation of one of the more complex layers to the first processor; and

program code to utilized a memory, accessible to each of the first processor and the second processor, for passing commands and data between the first processor and the second processor to permit the second processor to operate the one of the more complex layers for the benefit of the first processor.
