The risc v program below calculates the sum of the squares of all odd numbers between 0 and n, where n is an integer 100, using instructions from the risc v isa.
FACTORIAL OF A NUMBER:
.text # recursive implementation of factorial
.globl __start
fact: # arg: n in a0, returns n! in a1
addi sp, sp, -8
sw ra, 0(sp)
li t0, 2
blt a0, t0, ret_one # 0! and 1! == 1
addi a0, a0, -1
jal fact # call fact (n-1)
# a1 <- fact(n-1)
lw t0, 4(sp) # t0 <- n
mul a1, t0, a1 # a1 <- n * fact(n-1)
j done
ret_one:
li a1, 1
done:
lw ra, 0(sp) # restore return address from stack
addi sp, sp, 8 # free our stack frame
jr ra # and return
__start:
li a0, 5 # compute 5!
jal fact
li a0, 1 # print it
ecall
li a0, 17
ecall # and exit
