Document Table of Contents Pre-adder Constant Mode

In this mode, one multiplier operand derives from the input port, and the other operand derives from the internal coefficient storage. The coefficient storage allows up to 8 preset constants. The coefficient selection signals are coefsel[0..3].

This mode is expressed in the following equation.

The following figure shows the pre-adder constant mode of a multiplier.
