1. An asymmetric system comprising:

  • two or more ASIC chips wherein the chips are designed to work together to measure physiological signals, comprising;

    (a) a patch-ASIC chip adapted for incorporation into a physiological signal monitoring patch comprising a sensor interface, a processor coupled to the sensor interface, a memory element coupled to the processor, a radio coupled to the memory element that transmits data to a base-ASIC chip, and power management circuits that coordinate power usage on the chip; and

    (b) the base-ASIC chip, comprising a processor that processes sensor data, a memory element coupled to the processor, a radio coupled to the memory element that communicates instructions to the patch-ASIC chip, power management circuits for coordinating power usage on the chip, and a host interface through which the base-ASIC chip communicates with a host device;

    wherein the base-ASIC chip has more processing resources than the patch-ASIC chip.
