Explanation
1. This instruction multiplies the 32-bit single-precision floating-point number in S
point number in S
2. Instruction flags: SM600 (zero flag), SM601 (borrow flag), and SM602 (carry flag)

When the operation result is zero, SM600 is ON.

When the absolute value of the operation result is less than the value that can be represented by the minimum
floating-point number, the value in D is 16#FF800000 and SM601 is ON.

When the absolute value of the operation result is larger than the value that can be represented by the
maximum floating-point number, the value in D is 16#7F800000 and SM602 is ON.
