Abstract

An in-vivo sensing device having multiple imagers controlled by a single processor and a method for communicating between the processor and the imagers. The processor and imagers are connected via common data and control busses, instead of by direct separate conducting lines thereby reducing the number of pins on the processor and the corresponding number of conducting lines.

Claims

1. An in-vivo imaging device comprising:

a plurality of imagers;

a processor;

a single control bus to which each one of the plurality of imagers and the processor are coupled, for communicating control signals from the processor to the plurality of imagers; and

a single data bus to which each one of the plurality of imagers and the processor are coupled, for communicating data between the processor and the plurality of imagers.

2. The system according to claim 1, further comprising a separate reset line connecting between each imager and the processor, for resetting each imager separately.

3. The system according to claim 1, further comprising a single reset line connecting between all the imagers and the processor, for resetting all imager the imagers simultaneously.

4. In an in-vivo imaging device comprising a processor and a plurality of imagers, a method for communicating between the processor and the plurality of imagers comprising the steps of:

providing a control bus;

connecting each imager and the processor to the control bus;

associating with each imager identity information for uniquely identifying each imager; and

communicating control commands and associated identity information from the processor to the imagers.

5. The method of claim 4, wherein the processor communicates with the imagers cyclically.

6. The method of claim 4, further comprising the step of:

providing a data bus;

connecting each imager and the processor to the data bus; and

communicating data and associated identity information between the processor and the imagers.

7. The method of claim 6, wherein the data is communicated cyclically between the processor and the imagers.

8. The method of claim 6, further comprising the steps of:

providing a separate reset line between each imager and the processor, for resetting each imager separately; and

resetting the imagers separately prior to the step of communicating data between the processor and the imagers.

9. The method of claim 6, further comprising the steps of:

providing a single reset line between the imagers and the processor, for resetting the imagers; and

resetting all the imagers simultaneously prior to the step of communicating data between the processor and the imagers.
