Abstract
A system and method for conservation of battery power in a portable medical device is provided. In one example, a processor arrangement that includes a plurality of processors is implemented. At least one of these processors is configured to execute the critical functions of the medical device, while one or more other processors assume a reduced service level, thereby drawing significantly less power. According to this arrangement, the medical device conserves energy by drawing the additional electrical power needed to activate the additional processing power only when needed.
Claims23
An external medical device comprising:
- at least one cardiac sensor to sense cardiac data of a patient;
- a shared memory;
- and
- a processor coupled to the shared memory and comprising a plurality of cores, the plurality of cores comprising:
- a digital signal processor core, coupled to the at least one cardiac sensor, and configured to receive cardiac data sensed by the at least one cardiac sensor;
- and
- a general purpose processor core configured to monitor a condition of the patient based on at least the cardiac data.
An external medical device comprising:
- at least one cardiac sensor to sense cardiac data of a patient;
- at least one treatment electrode;
- a user interface;
- and
- a processor coupled to the at least one cardiac sensor, the at least one treatment electrode, and the user interface device and being configured to monitor a condition of the patient based on the cardiac data and provide treatment to the patient via the at least one treatment electrode, the processor comprising a digital signal processor core configured to receive cardiac data sensed by the at least one cardiac sensor and a general purpose processor core configured to provide at least one notification via the user interface based on the condition of the patient.
An external medical device comprising:
- a shared memory;
- a multi-core processor including a plurality of processor cores coupled to the shared memory, the plurality of processor cores including a general purpose processor core and a critical purpose processor core, the general purpose processor core being configured to process at least one event, and the critical purpose processor core being configured to:
- instruct the general purpose processor core to enter a reduced service state;
- detect at least one event that the general purpose processor core is configured to process;
- and
- instruct the general purpose processor core to enter an active state in which the general purpose processor core processes the at least one event.
