is it possible to map a multiply-accumulate operation to one DSP?
I have a synthesised design and it seems to consume 2 DSP units.

Potentially... It depends at least on:
-the width of your multipliers and accumulators
-how that maps into the target architecture (e.g. DSP48E1 for 7 series is a signed 25x18 with 48b accumulator)
-how you coded it
More info here:
and the applicable DSP48 guide, e.g. https://www.xilinx.com/support/documentation/user_guides/ug479_7Series_DSP48E1.pdf for Zynq-7000 and 7 series.
