Abstract

The present invention discloses an electronic data processing device with dual-CPU, comprising: the first CPU and the second CPU, wherein the first CPU is connected to the second CPU. The first CPU being low power type executes the first process which needs long time to execute. The second CPU with stronger computing ability in calculating than the first CPU executes the second process which requires quick arithmetic. The first CPU may output an interrupt to the second CPU in order to command the second CPU to execute the second process. The second CPU also can output an interrupt to the first CPU, thus to command the first CPU to transfer the data worked by executing the first process.

Claims

1. An electronic data processing device with dual-CPU, comprising:

a first CPU, being low power type, which executes the first process that needs long time to execute;

a second CPU with stronger computing ability than the first CPU which executes the second process that requires quick arithmetic;

wherein said first CPU being connected to said second CPU, and said first CPU outputting an interrupt to said second CPU to command the second CPU to execute said second process.

2. The electronic data processing device of claim 1, wherein the state modes of said second CPU comprise a initialize mode, a run mode and a standby mode.

3. The electronic data processing device of claim 2, wherein the second CPU in said standby mode is for receiving the interrupt send by the first CPU, then switching to said run mode.

4. The electronic data processing device of claim 1, wherein said first process comprise an external data collecting procedure.

5. The electronic data processing device of claim 4, wherein the first CPU is for outputting said interrupt to said second CPU so as to command said second CPU to execute said second process after the amount of the collected external data has reached to a predetermined amount.

6. The electronic data processing device of claim 4, wherein said second CPU is for outputting an interrupt to said first CPU initiatively when said second CPU has finished the processing of said external data, thereby to command said first CPU to transmit another new said external data to said second CPU.

7. The electronic data processing device of claim 4, wherein said first process further comprises a man-machine prompt procedure.

8. The electronic data processing device of claim 1, wherein the state modes of said first CPU comprise an initialize mode, a run mode and a standby mode.

9. The electronic data processing device of claim 8, wherein said second CPU is for outputting an interrupt to said first CPU, so as to command said first CPU to switch to run mode.

10. The electronic data processing device of claim 8, wherein said first CPU is for switching to said standby mode automatically after accomplishing the first process.

11. The electronic data processing device of claim 1, wherein said second process comprises a data receiving procedure.

12. The electronic data processing device of claim 1, wherein said second process comprises a data displaying procedure.

13. The electronic data processing device of claim 1, wherein said second process comprises a data writing procedure.

14. The electronic data processing device of claim 1, wherein said data processing device further comprises:

a man-machine output device, whose display data being provided and processed by said second CPU, being connected to said second CPU;

a man-machine input device, whose signals are processed by said second CPU, being connected to said second CPU;

a power management unit, which is connected to said second CPU.

15. The electronic data processing device of claim 14, wherein said man-machine output device is a monitor.

16. The electronic data processing device of claim 14, wherein said man-machine input device comprise buttons.

17. The electronic data processing device of claim 14, wherein said data processing electronic device further includes an external connector which is connected to said second CPU.

18. The electronic data processing device of claim 17, wherein said external connector is a memory card connector.

19. The electronic data processing device of claim 17, wherein said external connector is for connecting a long-distance electronic device.

20. The electronic data processing device of claim 19, wherein said long-distance device is a long-distance data processing system.

21. The electronic data processing device of claim 2, wherein said second CPU is for switching to said standby mode after accomplishing the second process initiatively.
