Description
Yes. There are two separate digital signal processing (DSP) block sign control signals: "Sign A" and "Sign B."
A logical
1
on the sign control signal indicates that the operand is a signed number. The result of the multiplication will be a signed number if any one of the operands is a signed number. The Sign A and Sign B signals affect the entire DSP block. Therefore, all the Data A inputs feeding into the
same DSP block must have the same sign representation. Similarly, all the Data B inputs feeding into the same DSP block must have the same sign representation. By default, the DSP block will implement signed multiplication.
