This assembly language improve upon multiplication of integer number in previous posting, to floating point multiplication. This program still use same algorithm for multiplication as hand scratch on primary school. 
.data
str1: .asciiz “Enter 1st number :\n”
str2: .asciiz “Enter 2nd number :\n”
str3: .asciiz “Content of FP register : “
str4: .asciiz “The result : “

This MIPS assembly code implements simple algorithm for multiplication.
#—– processing multiplication algorithm
addi $t0, $zero, 0 #prepare for product
addi $t7, $zero, 0
addi $t8, $zero, 0
addi $t7, $s4, 0 #prepare for multiplicand
addi $t8, $s5, 0 #prepare for multiplier
addi $s7, $zero, 1 #intialize for repetition
addi $t9, $zero, 16

Addition is a simple process for human. Entry the numbers in calculator or computer, then we’ll get the result. But sometime we should to know how it works. In MIPS processor, this is assembly language that shows the process. How bits go walk in registers, then appear result in output peripheral. You can use MARS tool from here
