Claim Text:
1. An implantable pulse generator (IPG) that generates spinal cord stimulation signals for a human body, comprising: a programmable signal generator having a plurality of control registers for storing stimulation signal parameters for a plurality of channels with each channel capable of being associated with at least two electrodes among a plurality of electrodes, each channel representing a stimulation signal pattern of the associated electrodes, wherein each electrode among the plurality of electrodes can be associated with two or more channels; a processor having a memory; a treatment control module stored in the memory and executable by the processor, the treatment control module adapted to transmit the stimulation signal parameters to the programmable signal generator for storage in the plurality of control registers, wherein the programmable signal generator generates the stimulation signals to drive the plurality of electrodes according to the stored signal parameters independently from the processor while the processor is in a standby mode; a timing generator adapted to generate timing signals representing stimulation signals for the plurality of channels according to the stored stimulation signal parameters; and an arbitrator that continuously receives the generated timing signals and selects one channel among the plurality of channels as an active treatment channel.
