DSP_REGISTER_PACKING_LEVEL

Controls how many levels of registers to be packed in the specified DSP instance, if registers are available. Setting the packing level to 0 is equivalent to disabling DSP register packing operation of the DSP. If the packing level is set to 1, the Fitter tries to pack one layer of registers from the DSP's input side. When set to 2, an additional layer of registers will get packed from DSP's output side. 3 or 4 will add one or two layers of the pipeline registers from the input side.
