Convert the following C program into the RISC-V assembly code. You should look up a table to convert the lines manually and you can use "ecall" when appropriate (Don't make it too complicated than it needs to be):

#include

int main()

{

int x = 30, y = 17;

printf("x * y = ");

printf("%d\n", x*y);

return 0;

}

Expert Solution

the above mentioned c program is converted into RISC - V assembly code as follows :

.LC0:

.string "x * y = "

.LC1:

.string "%d\n"

main:

addi sp,sp,-32

sd ra,24(sp)

sd s0,16(sp)

addi s0,sp,32

li a5,30

sw a5,-20(s0)

li a5,17

sw a5,-24(s0)

lui a5,%hi(.LC0)

addi a0,a5,%lo(.LC0)

call printf

lw a4,-20(s0)

lw a5,-24(s0)

mulw a5,a4,a5

sext.w a5,a5

mv a1,a5

lui a5,%hi(.LC1)

addi a0,a5,%lo(.LC1)

call printf

li a5,0

mv a0,a5

ld ra,24(sp)

ld s0,16(sp)

addi sp,sp,32

jr ra

Write a program in "RISC-V" assembly to convert an ASCII string containing a positive or negative integer decimal string to an integer. ‘+’ and ‘-’ will appear optionally. And once they appear, they will only appear once in the first byte. If a non-digit character appears in the string, your program should stop and return -1.
