An apparatus comprises an integrated circuit (IC) including sequencer circuitry; and a memory integral to or operatively coupled to the integrated circuit, wherein at least a portion of the memory is organized as a plurality of hierarchical linked lists defining a finite state machine of a plurality of finite IC states; wherein the sequencer circuitry is configured to: receive one or more control words from the hierarchical linked lists associated with an IC state; advance the IC to the IC state according to the one or more control words; and perform one or more actions corresponding to the IC state.
