Processing details
This instruction divides the input value 1 (E1) by the input value 2 (E2).
The S.DIV instruction performs the following operations.
K1×E1+B1
BW=A× +B3
K2×E2+B2
When the denominator (efficient 2 (K2)input value 2 (numerator) (E2) + bias 2 (B2)) is 0, the output value (BW) becomes
bias 3 (B3).
