Write a MIPS program with the following specifications:

Use the my_mul function in question 1 to create a function which computes factorials: n! = n. (n - 1). … 3 .2 . 1

Note: You can only use my_mul function, and not use other functions).

Each function must save all variables it modifies.

below is my_mul my_mul :

#multiply $a0 with $a1

#does not handle negative $a1 !

#Note : This is an inefficient way to multiply !

addi $sp, $sp, -4 #make room for $s0 on the stack

sw $s0, 0( $sp ) #push $s0

add $s0, $a1, $0 #set $s0 equal to $a1

add $v0, $0, $0 #set $v0 to 0

Answer #1

Q) Write a MIPS program with the following specifications: Use the mymul) function in question 1 to create a function which computes factorials: n!n. (n - 1) 3.2.1 Ans: Function mymul() like a three operand mul and produce less significant half of the double length result. Static int inline mymul(int a,int b) Int p; Asm{ mul %0,961,962 :-rph Return p; Main lw Şa0, num jal fact sw $v0,ans j exit fact: subu Şsp,$sp,8 sw Srs, ($sp) sw $s0,4(Ssp) li Şv0,1 beq Şa0,Şzero,done move $s0,$a0 subi Şa0,Şa0,1 jal fact done: lw $ra, (Ssp) lw $s0,4($sp) addu $sp,Şsp,8 jr $ra exit:

    Subroutines in MIPS Determines the minimum of two integers Functions within the MIPS slides describe how one can use subroutines (also called procedures, functions, and methods) in MIPS. Because of the importance of subroutines in modern programming, most hardware designers include mechanisms to help programmers. In a high-level language like C or Java, most of the details of subroutine calling are hidden from the programmer. MIPS has special registers to send information to and from a subroutine. The registers $a0,...
