$.$ Translate function f$()$ in the following C code to RISC$-$V assembly code. Assume function g

has already been implemented. The constraints are:

$1)$ Allocate register s$1$ to sum, and register s$2$ to i$.$

$2)$ Save registers at the beginning of the function and restore them before the exit.

$3)$ There are no load or store instructions in the loop. If we want to preserve values

across function calls, place the value in a saved register before the loop. For example,

we keep variable i in register s$2.$

Your code should follow the flow of the C code. Write concise comments. Clearly mark

instructions for saving registers, loop control, function, restoring register, and so on$.$

Reminder: the callee can change any temporary and argument registers.

$//$ prototype of g

$//$ the first argument of g is an address of an integer

int g$($int $*$ a$,$ int i$)$;

int f$($int d$[1024])$

$\{$

int sum $=0$;

for $($int i $=0$; i $<1024$; i $+=1)\{$

sum $+=$ g$($&d$[$i$],$ i$)$; $//$ pass d$[$i$]$s address to g

$\}$

return sum;
