|---|---|
| NSA | Calculates the left-shift amount needed to normalize a 32-bit two’s-complement number. |
| NSAU | Calculates the left-shift amount needed to normalize a 32-bit, unsigned number. |
| MIN | Selects the minimum value operand from two input operands stored in two’s-complement format. |
| MAX | Selects the maximum value operand from two input operands stored in two’s-complement format. |
| MINU | Selects the minimum value operand from two input operands stored in unsigned format. |
| MAXU | Selects the maximum value operand from two input operands stored in unsigned format. |
| CLAMPS | Signed clamping function, used for saturating arithmetic. |
| SEXT | 32-bit sign extension. |
