Question

15. A third degree polynomial equation (a cubic equation) is of the form p(a) caz chac Co, where r and the into registers $t0, $t1, St2, and St3, respectively. Suppose the value of z is in $17. Write the MIPS32 instructions that would evaluate this polynomial, placing the result in St9. 16. Let $to 0xFEDC 4321, $t1 0x9876 ABCD, and St2 AAAA AAAA. Suppose the following sequence of in structions (on the next page) is performed exactly four times, i we execute instructions 1-4, we repeat executing instructions 1-4, we repeat executing instructions 1-4, we repeat executing instructions 1-4, and then we stop. Show the contents of $t0, $t1, $t2, and $t3, after we stop. Write your answers in hex. c) Kevin R.

Please help me to answer those three questions.

Answer 1

1)char ch1-",ch2-"$" ch1: .byte ch2: .byte $' 2)int x-0,y -1,z; x: .word 0 y: .word -1 Word 0 3) name: .asciiz "Merge Simpson" 4) iarray: .space 250*4 5) carray: .space 250

in this code i tacking the value of c0,c1,c2,c3 and x for testing purpose but you change it accrding to your need
