in this part you are asked to recognize what a given segment of machine code does, by translating it into assembly code, and annotating it with expressions in a high level language like C. This process from binary code back to source code, is called disassembling. Disassemble the following machine code into operations and arguments, e.g., ADD R1, R2, R3. Explain what the whole program does, either in plain English (e.g., it calculates the product of R1 and R2) or in C type of pseudo code (e.g, R3 = R1 * R2.) Note: you need to make up unique labels for your assembly code

The following instruction set is supported by a simple processor, which is similar to what we discussed in the class, with a few new instructions added. The format of most instructions is defined as follows. bits 15:14 13:10 98:65:32:0 f ficld unused opcode w src1 where the fields are defined as follows opcode: operation to be performed by the processor write back ALU output to register file (1 = yes, 0 = no) W. src address of the first ALU operand in the register file address of the second ALU operand in the register file address in the register file where the output is written SrC dst: For opcodes BEQ, BLEZ and JUMP, the 6 least significant bits (5:0) give an address in the instruction memory, which is byte-addressed. The opcode HALT has all operand bits (9:0) being 0. When an instruction has only two operands, the field for the unused operand is filled with 0-bits. For example, bits (5:3) for SLL are all zero because src2 is not used. The opcode and meaning of these instructions are listed in the following table.
