12.11 Assignment 1 - Question 2 This lab will be available until May 6th, 11:59 PM MST Given the mapping of registers to variables below, write a program to implement the following expression: y=((x1+x3)(x5x7))+((x4x2+x6)+(x5x1)) You may use any temporary registers from \$tt to \$t9. Clearly specity your choice of registers using comments (5 points). Important : Do not simplify the expression. Example Test: If the values of $s1 through $s7 are initialized in the simulator as: You may use any temporary registers from St0 to St9. Clearly specify your choice of registers using comments (5 points). Important : Do not simplify the expression. Example Test: If the values of $s1 through $s7 are initialized in the simulator as: the result is stored in $s0 : Note: Use the ' + ' button under the Registers display to initialize register values for $s1,$s2,$s3,$s4,$s5, $s6 and $s7
