$[$b$]$ Consider a $4-$stage instruction pipeline and four instructions need to be$[$b$]$ Consider an array of $100$ elements, where each element of an array

occupies $4$ words in the memory. The size of the entire cache is $32$ words.

The cache is further divided into $8-$words per block$/$line of cache. Consider

the following statement:

for $(i=0$;

$q$ for $(j=0$;$j<mn>1</mn><mn>0</mn>$;$j++)$

$,A[i][j]=A[i][j]+10$;

Find the hit ratio of the above code if the elements of the $2-$D array are stored

in row$-$major order. How does the hit ratio change if the elements are stored

in column$-$major order?

executed on the pipelined processor. The instructions consume different

number of clock cycles at different stages as shown below:

The following code has to be executed on the pipelined processor:

I$1$ instruction is first executed followed by $12,13$ and $14,$ and the process repeats $100$

limes$.$ After how many clock cycles the output of the instruction $12$ for $j=2$ will be

available?
