2.5. Multipliers for Fixed-Point and Floating-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:

Table 6.  Operational Modes
Fixed-Point Arithmetic Floating-Point Arithmetic
  • Two 18 (signed or unsigned) x 19 (signed) multipliers
  • One 27 x 27 multiplier
  • One floating-point arithmetic single precision multiplier
