How do multiply a 64bits with 32 bits in MIPS

Question

Im trying to multiply two 32bits in mips. So the result is stored in the high and low register. How can I multiply the 64bit to a 32 bit when the answer is stored in two registers?

Answer 1

You multiply each half of the 64-bit value by the 32-bit value, then add the matching registers together, realizing you may need a third 32-bit register to represent the result.
