Processing details
• These instructions calculate the square root of binary 32-bit data specified by (s1), and store the operation result in (d).
Precautions
• The obtained square root is an integer because the decimal point is ignored. When the calculated decimal value is ignored,
SM8021 (borrow flag) turns on.
• When the operation result is true 0, SM8020 (zero flag) turns on.
