The present invention relates to a method and apparatus for intra prediction. The damping chamber is located adjacent an inlet side of the relief valve, and the check valve includes a sealing member to prevent fluid flow into the damping chamber at the inlet side. A coil excess energy storage element may be connected to the coil nodes of the circuit, through alternate current path elements and utilized to temporarily store the discharging of the excess coil energy normally available because of the lagging nature of the motor coil current. The systems and methods further provide a technique for automatic routine selection based on the add-on instruction state information such that the add-on instruction executed corresponds to a current state.
