The input registers feed the multiplier blocks. These registers can increase the DSP block performance, but are
optional. These registers can also function as shift registers if the dedicated shiftin/shiftout signals are used.
The pipeline registers are fed by the multiplier blocks. These registers can increase the DSP block performance, but
are optional.
The output registers register the DSP block output. These registers can increase the DSP block performance, but are
optional.
