Your question is not clear to me.
For e.g. in a Zynq based 7 series Xilinx FPGA, the DSP48E1 Slice (containing many basic elements such as adder, mult, etc.) is one basic DSP unit. In you design you can instantiate the DSP48E1 Slice.

I don't think it is possible because the operand width is 25x18 in the DSP48E1.

The Accumulators in the DSP slice can be run in SIMD (single instruction, multiple data) mode, but this prevents the use of the multiplier.
