Question

Assume that I don't know anything about this.
Answer wise, I already have it.
Please provide step by step guide towards any thought process. 
Thank you!
(this is a course in MIPS assembly)

**Problem 5: Determining Register Values in MIPS Assembly Language** In this exercise, we'll determine the values stored in the temporary registers $t0, $t1, $t2, and $t3 after executing a given block of MIPS assembly code. You can provide the values in decimal integer format or binary. Note that only the least significant byte of each word needs to be shown. If the value for any register cannot be determined with the information provided, label it as "Undefined." ### MIPS Code: 1. `li $t0, 3` 2. `sll $t1, $t0, 2` 3. `or $t2, $t1, $t0` 4. `and $t3, $t2, $t0` ### Explanation of Instructions: 1. **li $t0, 3**: - Load the immediate value 3 into register $t0. 2. **sll $t1, $t0, 2**: - Shift the bits in $t0 left by 2 positions and store the result in $t1. - This operation is equivalent to multiplying the value in $t0 by 4. 3. **or $t2, $t1, $t0**: - Perform a bitwise OR between $t1 and $t0 and store the result in $t2. 4. **and $t3, $t2, $t0**: - Perform a bitwise AND between $t2 and $t0 and store the result in $t3. ### Results: - **$t0**: 3 - **$t1**: $t0 << 2 = 3 * 4 = 12 - **$t2**: $t1 | $t0 = 12 | 3 = 15 - **$t3**: $t2 & $t0 = 15 & 3 = 3 These operations demonstrate basic bit manipulation and arithmetic in MIPS assembly language. Understanding these operations is crucial for efficient low-level programming and optimizing code at the hardware level.
