Problem $1$## Complete the following procedure so that it returns the value of a bit from a# bit vector that spans one or more bytes. Register $`$$a$0`$ holds the start# address of the bit vector and register $`$$a$1`$ holds the bit number to retrieve.# The most$-$significant bit of the first byte is bit number $0($remember that MIPS# is big$-$endian$).$ The return value $($i$.$e$.,$ the value of the register $v$0)$ should# be set to $0$ or $1.$# For example, a $16-$bit bit vector is specified in the assembler below starting# at the label bit$\_$vector$\_$start:# bit$\_$vector$\_$start:# $.$byte $0$xc$5,0$x$1$f# In binary this would be $1100010100011111.$ If getbit were called with $a$1=0$# then bit number zero, meaning the leftmost bit in $11000101000111112,$ should# be returned and so $v$0=1.$ For $a$1=2$ a $0$ should be returned.# When you run the code in hw$1.$s a testbench routine will call getbit several# times. For each call the testbench will print the value returned by getbit# $($meaning the value of $v$0),$ whether that value is correct, and if wrong, the# correct value. At the end it will print the number of incorrect values# returned by getbit, which hopefully will be zero when you are done.# It is important that each line of code is commented succinctly with enough# clarity so anyone can follow the logic behind your code. Again writing comment# is part of the solution, code without sufficient comments even if it is# correct, will only receive half of the grade.
