Using MIPS Assembly Language

You are tasked to calculate a specific algebraic expansion, i.e. compute the value of f and g for the expression:

f = (A^4 - 4B^3 + 3C^2 - 2D)

g = (A * B^2 + C^2 * D^3)

Without using any intrinsic multiplication instructions, subroutines, and function calls. More formally,write MIPS assembly code that accepts four positive integers A, B, C, and D as input parameters. Thecode shall execute in MARS to prompt the user to enter four positive integers represented in decimal,each separated by the Enter key. The program will then output f and g in decimal and binary, using syscall routines for each output.

NOT ALLOWED TO USE  { mul, mul.d, mul.s, mulo, mulou, mult, multu, mulu, div, divu, rem,sll, sllv, sra, srav, srl, srlv }

Explanation / Answer

LC0:
.string "Enter values of A , B, C ,D "
.LC1:
.string "%d%d%d%d"
.LC2:
.string "The value of f is %d :"
.LC3:
.string "The value of g is %d:"
