Using the AddTwo program from Section 3.2 as a reference, write a program that calculates the following expression: using registers: A = (A + B) - (C+D) Assign integer values to the EAX, EBX, ECX, and EDX registers.

Write a sequence of statements that display a subroutine’s return address. Hint: the esp register points to the return address stored on the call stack. You can call procedure WriteHex. This can be solved in 2 lines of code.    The following exercise can be solved using either 32-bit or 64-bit code. Assembly language

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 9 8:6 5:3 2:0 field unused opcode w srcl src2 dst 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) 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 w: srcl: src2: 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…

Write an interactive program that inputs the coefficient of a quadratic equation, computes, and displays the roots of the quadratic equation. All input, computation, and output should be done using double-precision floating-point instructions and registers. The program should handle the case of complex roots and displays the results properly. note: the solution should be in MIPS assembly language.
