write a mips assembly code that creates the 32-bits constant ll/sc and stores that value to register ＄t1

在MIPS汇编语言中，创建32位常数`ll/sc`并将其存储到寄存器`$t1`通常涉及到将十进制、十六进制或八进制数值直接编码到二进制形式。由于MIPS指令集支持操作码寻址和字节操作，我们可以使用`li` (load immediate)指令加载立即值。这里是一个示例，假设我们要存储的32位无符号整数是0x12345678：

# MIPS assembly code
.data
ll_sc: .word 0x12345678   # 存放32位常数

.text
.globl main
main:
    addi $sp, $sp, -4     # 临时堆栈空间
    sw $zero, 0($sp)      # 将当前链接地址压入堆栈
    
    # 将ll/sc常量加载到$t1寄存器
    li $t1, 0x12345678    # 使用li指令加载32位无符号整数到$t1
    lw $zero, 0(ll_sc)    # 从数据区加载常量到内存位置
    move $t1, $zero       # 将内存中的值复制到$t1
    
    # 可选：清理堆栈并返回
    lw $zero, 0($sp)
    addi $sp, $sp, 4
    jr $ra                 # return to previous address

write a mips assembly code that creates the 32-bits constant ll/sc and stores that value to

在MIPS汇编语言中，为了创建一个32位常量并将其存储到内存中，你可以使用`li`（load immediate）指令来加载立即值，然后使用`sw`（store word）指令将值存储到指定地址。假设你想存储的常量是一个无符号整数，你可以这样做：

.data
constant_value: .word 0xABCDEF12       # 32位常量，十六进制表示

.text
.globl main
main:
    li $t0, 0xABCDEF12      # 使用$t0寄存器存放常量
    la $t1, constant_value   # 计算constant_value存储地址偏移
    sw $t0, 0($t1)          # 将$t0的内容存储到address + 0 (即constant_value)

    # 程序结束
    jr $ra                    # return to calling address

这里，`$t0`寄存器用于暂存数值，`la`（load address）指令获取存储地址，`sw`指令则实际执行存储操作。

Provide the type and hexadecimal representation of following instruction: sw $t1, 32($t2)

The given assembly language instruction `sw $t1, 32($t2)` is a MIPS instruction that stores the contents of register `$t1` to the memory location specified by the sum of the value in register `$t2` and the immediate offset `32`. This instruction is used to store data from a register to memory.

The type of this instruction is a memory access instruction, specifically a store word instruction.

In hexadecimal representation, this instruction would be:

0x25490020

This hexadecimal representation corresponds to the following binary representation:

0010 0101 0100 1001 0000 0000 0010 0000

Here, the first 6 bits (001001) represent the opcode for the store word instruction, the next 5 bits (01001) represent the destination register `$t1`, the next 5 bits (01001) represent the source register `$t2`, and the last 16 bits (0000001000000000) represent the 16-bit signed immediate offset value `32`.
