struct algae$\_$position $\{$

float x;

$\}$;

struct algae$\_$position grid$[16][16]$;

float total$\_$x $=0,$ total$\_$y $=0$;

int i$,$j;

You should also assume the following:

$$ sizeof$($float$)==4.$

$$ grid begins at memory address $0.$

$$ The cache is initially empty.

$$ The only memory accesses are to the entries of the grid array grid. the variables i$,$ j$,$ total x$,$ total y are stored in registers.

We consider the following code:

for $($i $=0$; i $<16$; i$++)\{$

for $($j $=0$; j $<16$; j$++)\{$

total$\_$x $+=$ grid$[$j$][$i$].$x;

total$\_$y $+=$ grid$[$j$][$i$].$y;

$\}\}$
