Answer:
R-Type Instructions: These instructions are identified by an opcode of 0, and are differentiated by their funct values. Except for the first 3 shift instructions, these operations only use registers. Note that in addition to arithmetic operations, these instructions also include jumps and the system call instruction.
These instrutcions have:
Example:
add $s0, $s1, $s2
J-Type Instructions: These instructions are identified and differentiated by their opcode numbers (2 and 3). Jump instructions use pseudo-absolute addressing, in which the upper 4 bits of the computed address are taken relatively from the program counter.
Example:
j Loop
I-Type Instructions: These instructions are identified and differentiated by their opcode numbers (any number greater than 3). All of these instructions feature a 16-bit immediate, which is sign-extended to a 32-bit value in every instruction (except for the and, or, and xor instructions which zero-extend and the lui instruction in which it does not matter). Branch instructions also effectively multiply the immediate by 4, to get a byte offset.
These instructions have:
Example:
lw $t0, 32($s3)

Should be written in Python: A disassembler takes a machine code file (binary) and converts it back into assembly code. Disassemblers are a key tool in the software reverse engineering process because it allows you to go from the raw binary all the way back to the original source code, if desired. For this assignment you will be given 8 32-bit binary strings and the type of the instruction (I-type, R-type, or J-type). You’ll write a basic disassembler in Python...
