The first program will demonstrate a variety of MIPS instructions. Your program should begin by loading the contents of four integer operands (A, B, C, and D) into registers. Next, your program should use the shift and rotate instructions described in the Patterson/Hennessy textbook to multiply the value of A by 6, divide the value of B by 8 (truncating the result), shift the value of C to the right 10 bit places (writing 0s into the most significant bits of the register), and rotate the value of D 12 bit places to the left. Finally, your program should write the new values of A, B, C, and D back to memory. Be sure to test your program carefully, using both positive and negative integers for inputs. Validate correct program operation by examining the updated contents of the memory operands. (HINT: 6A = 2A + 4A!)
