(30 points) For each of the following SIC/XE instruction object codes (in hexadecimal format): 0x034026, 0x75101040, 0x3E2035, determine and write the following information for each instruction: i. Instruction format, ii. Mnemonic of the opcode, (Note: if an instruction format specifies 6 bits for the opcode portion, append two bits 00 to the 6 bits opcode from the object code to match the opcode column from the instruction reference to find the corresponding mnemonic of the opcode) iii. Addressing Modes - addressing mode for computing the target address, and addressing mode for using the target address to get the operand value, iv. Target Address, and v. Operand value. Briefly explain how you derive the information for the target address, and the operand value. An instruction reference table, a memory table, and a register table are given as follows (all numbers in these three tables are in hexadecimal format).
