2.1.5. Multipliers for Fixed-point Arithmetic

A single-variable precision DSP block can perform many multiplications in parallel, depending on the data width of the multiplier and implementation.

There are two multipliers per variable precision DSP block. You can configure these two multipliers in several operational modes:
  • Four 9 (signed) x 9 (signed) multipliers or four 8 (unsigned) x 8 (unsigned) multipliers
  • Two 18 (signed or unsigned) x 19 (signed) multipliers
  • One 27 (signed) x 27 (signed) multiplier
