You can efficiently construct an individual 36-bit multiplier with two adjacent variable precision DSP blocks. The 36 x 36 multiplication consists of four 18 x 18 multipliers, as shown in Figure 34 .

The 36-bit multiplier is useful for applications requiring more than 18-bit precision; for example, for the mantissa multiplication portion of very high precision fixed-point arithmetic applications.
