3.2.2.3. Vector Two Mode

This mode performs floating-point multiplication where the multiplication result is directly fed to chainout. The chainin input from the previous variable DSP Block is then added or subtracted from input ax as the output result.

Disable

result = ax

Chainout = ay * az

result = ax

Chainout = ay * az

Enable

result = ax + chainin

Chainout = ay * az

result = ax - chainin

Chainout = ay * az

The floating-point vector two mode supports the following exception flags:
  • mult_invalid
  • mult_inexact
  • mult_overflow
  • mult_underflow
  • adder_invalid
  • adder_inexact
  • adder_overflow
  • adder_underflow
