1. An implantable biosignal processing system comprising:

  • a first processing system comprising an analog signal processor having a plurality of analog signal processing circuits, wherein the first processing system is configured to connect to a lead comprising one or more biosignal sensors for acquiring and processing electrophysiological data of a brain region of a subject; and

    a second processing system in communication with the first processing system, the second processing system comprising a digital signal processor having a power management circuit and a plurality of digital signal processing circuits in communication with the power management circuit, wherein the power management circuit selectively activates and/or deactivates digital signal processing circuits according to a treatment mode of the second processing system to generate a set of electrophysiological data characteristics, andwherein each digital signal processing circuit has a data and clock controller configured to adjust a clock signal of the digital signal processing circuit based on at least one characteristic of the set of electrophysiological data characteristics.
