Reconfigurable digital network for processing data in an implantable medical device

A method of processing data in an implantable medical device (IMD) comprising:

• with an implantable main processing unit of the IMD selectively reconfiguring the coefficient and delay values of a reconfigurable processor unit of the IMD;
• directing data to the reconfigurable processor unit, via operation of the implantable main processing unit, to perform a digital signal processing (DSP) operation;
• switching the implantable main processing unit into a low-power mode;
• and
• performing the DSP operation, via operation of the reconfigurable processor unit, while the implantable main processing unit is in the low-power mode.

An implantable medical device (IMD) comprising:

• sensing means for sensing data;
• an implantable general processing means, coupled to the sensing means, for executing general operational functions within the IMD;
• memory means, coupled to the general processing means, for storing the data;
• an implantable reconfigurable processing means, reconfigurable by the general processing means and coupled to the general processing means, for performing a digital signal processing (DSP) operation on the data;
• and
• reconfiguration means, coupled to the reconfigurable processing means, for programming coefficients of the reconfigurable processing means to thereby program the DSP operation.
