Using the MARIE computer assembly language, write a program that computes the following expression: z= a*b* c. The computer will read in the input values a, b, and c from the keyboard and the final result (z) have to be displayed. In addition, every time an input value is read in, it must be displayed on the screen. Remember that the instruction set does not have an instruction to execute multiplication. The program must be tested on MARIE simulator.

Write a program in MARIE assembly language to perform following code segment. Test yourcode thoroughly using MARIE simulator with values of X=10, X=20, and X=30. What is thevalue stored in X and Y by the end of execution? Include comments for each line of instructionin your program. X = 10Y = 0while X <= 10 do; Y = X – 1 X = X – 2endwhile;

Write an assembly code to implement the y = (x1+x2) * (x3+x4) expression on 2-address machine, and then display the value of y on the screen. Assume that the values of the variables are known. Hence, do not worry about their values in your code. The assembly instructions that are available in this machine are the following: Load b, a Load the value of a to b Add b, a Add the value of a to the value of b and place the result in b Subt b, a Subtract the value of a from the value of b and place the result in b Mult b, a Multiply the values found in a and b and place the result in b Store b, a Store the value of a in b. Output a Display the value of a on the screen Halt Stop the program Note that a or b could be either a register or a variable. Moreover, you can use the temporary registers R1 & R2 in your instructions to prevent changing the values of the variables (x1,x2,x3,x4) in the expression. In accordance…
(a) Write an assembly language program for the Intel 8086 microprocessor that divides a 32-bit number by a 16-bit word and stores the results i.e., quotient and reminder, in separate memory locations? (Choose the dividend and divisor by yourself).In the assembly language program, make sure to properly define the different segments using the appropriate assembler directives.(b) Draw an appropriate flow diagram for this program.
For all the questions in this assignment, you should use conditional execution of branch instructions only (i.e., do not use conditional execution of data processing instruction or other non-branch instructions). Question #1 . For each of the following C++-like pseudo code segments, write equivalent ARM assembly language instructions. if (r1 >= 10) { r2 = r2 - r1; } r2 = r2 + 60; if (r4 < 0) r4 = r4 + 100; else r4 = 100 - r4; if (r5 == r6) r5 = r5 + 80; else if (r5 < r6) r5 = r5 - 40; else if (r5 != r8) r5 = -r5; else r5 = 9*r5;
Suppose the logic blocks used to implement the processor as discussed in class have the following delays: Instr/Data Memory Access Register File Decode+Read Mux ALU Adder (outside ALU) Single gate delay Register read Register Write Sign Extend 250ps 150ps 25ps 200ps 150ps 5ps 30ps 20ps 50 a) How much time would you expect to take to execute an R-type instruction based on the details studied in class? b) How much time would you expect to take to execute an lw instruction based on the details studied in class? (0.4 c) Based on these two questions, is it possible to guess what would the (minimum) clock cycle time be of such a processor if the instructions are executed in one cycle? If yes, indicate it. If it is not, state the reason why not.
A word in main memory may contain an instruction or a binary number in twos complement notation. Demonstrate that this instruction repertoire is reasonably complete by specifying how the following operations can be programmed: (a) Data transfer: location X to accumulator, accumulator to location x (b) Addition: Add contents of location X to accumulator (c) Conditional branch (d) Logical OR (e) I/O operations
