Ambulatory recorder having a communication watchdog between two processors
First Claim
1. An ambulatory medical recording system comprising:
- a medical sensing catheter;
a medical data recorder coupled with the medical sensing catheter, the medical data recorder comprising;
a first processor and a second processor, the fist and second processors communicating along a first line, the first processor comprising means for sensing a communication failure between the first processor and the second processor, the first processor further comprising means for resetting the second processor in response to sensing the communication failure.

Abstract
An ambulatory recording system, for medical and especially diagnostic purposes, is described having a communication watchdog between two processors. The two processors may be of differing types. For example, the first processor may be real time processor ("RTP") which handles the sampling function, while the second processor may be a non real time processor ("NRTP") which handles the operating system function. This dual processor design permits relatively low power consumption for data recording (which is handled by the relatively lower power consuming RTP), while also providing a graphical user interface for user simple user operation (which is handled by the relatively higher power consuming NRTP). A communication watchdog between the two processors is provided to reset the device upon the detection of a processor failure or communication failure between the two processors.
