3.5.5. Adder

You can use the adder in various sizes, depending on the operational mode:

  • One 64-bit adder with the 64-bit accumulator
  • Two 18 x 19 modes—the adder is divided into two 37-bit adders to produce the full 37-bit result of each independent 18 x 19 multiplication
  • Three 9 x 9 modes—you can use the adder as three 18-bit adders to produce three 9 x 9 multiplication results independently
