RISC-V 循环遍历单词数组

Question

In my assignment for class the professor asked us to loop through an given array of 10 numbers and print them, and the following was provided as skeleton code:

.data
arrayOfNums:
.word 0
.word 1
.word 255
.word 65536
.word 4294967295
.word 22
.word 314159
.word 161803
.word 42
.word 131929

K: .word 1337

.text
.globl main

main:
*Code goes here*

I don't understand how to go down the list of words from arrayOfNums. This is my first time coming into contact with any sort of assembly language so a detailed explanation would be extremely helpful, thanks guys

Answer 1

In your code you have to solve the following tasks:

• load the start address of your array into a register
• loop over the array, ieload each element from the current address,
• print the loaded value with the right ecall
• increment the address of the current element by as many bytes as a word occupies,
• conditionally branch to the start of the loop if the address is still part of the array - hint: K symbolizes the address that immediately follows your last array element
• call an exit ecall to terminate your program
