如何在mips中将char数组的元素初始化为二维数组？

如何解决如何在mips中将char数组的元素初始化为二维数组？

根据c代码，数组p的基地址中的值应该与数组str的基地址相等，但它们不匹配我还是mips assbley的新手，所以请原谅我，随时做任何编辑提前致谢 我认为问题在于加载字节并将字节存储在数组中，但仍然无法弄清楚， 我留下了汇编代码的额外部分，以便让查看者更容易了解代码的内容，但我具体询问的部分在 while 循环内

this is the psudo code

i=0;
j=0;
k=0;
while(j < my_strlen(str))
{
    if (str[j] == ' ')
    {
        p[i][k] = '\0';
        i++;
        k = 0;
    }
    else
    {
        p[i][k++] = str[j];
    }
    j++;
}

this is my attempted mips code

.data

 str: .space 30       # get the paragraph from the user
 p: .space 400        #p[20][20]
    
 
 stringlen: .asciiz "String length is "
 blankSpace: .ascii  " "
.text
