Note to Tables 1–1 and 1–2:
(1) This parameter lists the total number of 9 × 9-bit multipliers for each device. For the total number of 18 × 18-bit
multipliers per device, divide the total number of 9 × 9-bit multipliers by 2. For the total number of 36 × 36-bit
multipliers per device, divide the total number of 9 × 9-bit multipliers by 8.
