Question 01 : (a) Write an assembly language program for the Intel 8086 microprocessor that adds two 16-bit words in the memory locations called ADD1 and ADD2, respectively, and stores the result in a memory location SUM? In the assembly language program, make sure to properly define the different segments using the appropriate assembler directives. (b) Draw a diagram showing the data arrangement in memory for the multiply program you wrote in section (a)?

3. Create an 80x86 ASSEMBLY LANGUAGE program that define an array of doubleword numbers then read twovalues, first one indicates how many actual numbers will be in the array, and an integer n. Theprogram should display all of the numbers in the array that are greater than the number n. MUST PROVIDE FULL CODE AND SCREENSHOT OF OUTPUT PLEASE

For each question, give the following three values for the last line of each code block following the execution of the entire block: 1. the memory address which that line writes to, 2. the value that is written to that address, and 3. the number of distinct memory reads required by that line. If you cannot determine the memory address from the information given, enter 0 for the address. When computing the number of memory reads, assume nothing about the value of registers prior to the execution of the last statement: count a read even if the previous line also read (or wrote) the location. Count the number of distinct memory locations read by that statement; that is, if the line reads a memory location multiple times, count it only once. Assume that memory accesses always succeed, i.e. that all memory addresses are accessible to the program. For example, for the following code block: int *foo (int *)0x1000; int *bar = (int *)0x1000; *foo = 1; *foo=foo + *bar + 1; you would answer…
PLEASE DON'T USE STRUCTS Using C programming language write a program that simulates a variant of the Tiny Harvard Architecture. In this implementation memory (RAM) is split into Instruction Memory (IM) and Data Memory (DM). Your code must implement the basic instruction set architecture (ISA) of the TinyMachine Architecture: 1 -> LOAD 2->ADD 3->STORE 4 -> SUB 5 ->IN 6-> OUT 7-> END 8 -> JMP 9 -> SKIPZ Each piece of the architecture must be accurately represented in your code (Instruction Register, Program Counter, Instruction Memory (IM), MAR1, MDR-1(MAR-1 and MDR-1 are connected to the IM). Data Memory, MAR-2, MDR2 (MAR-2 and MDR-2 are connected to the DM), and Accumulator. Instruction Memory will be represented by an integer array and each instruction will use 2 elements of the array(one for OP and the other one for address) Data Memory will be represented by an integer array and each data value uses an element of the DM array. Your Program Counter will begin pointing to the first…
A simple two-pass assembler does the following in the first pass: A. It allocates space for the literals. B. It computes the total length of the program. C. It builds the symbol table for the symbols and their values. D. It generates code for all the load and store register instructions. E. None of the above.
In assembly 68k write the: Initialize the supervisor stack pointer to $8000 Initialize the program counter to $1000 Reserve locations at $2000 to hold your first name only (Joshua) as text and call it NAM Reserve locations at $3000 to store 9 longwords, call it MEM, and write your family name (Kimmich) as a comment Reserve locations at $12400 to store 32-bit unsigned integer variable called RES (to be computed)
(a) In MIPS machine language, the R format instructions need an additional field (the “funct” field) to specify the instruction type (“add”, “sub”, etc.). Why can’t this be done using just the 6-bit “op” field, which all MIPS instructions have, instead? (b) Give a sequence of MIPS assembly language instructions that adds the contents of $s0 and $s1, storing the result into $s0, if the contents of $s1 are greater than 6. Otherwise, the contents of $s0 should be incremented by 28. In either case, afterwards the contents of $s0 should be copied into $s2. (c) Suppose that the starting address of an array of words is stored in $s0. Give a MIPS assembly language instruction that loads the contents of the second word in the array into $s1. (d) Suppose that A and B are defined using “A: .word 0”, and “B: .space 100”. Give a sequence of MIPS assembly language instructions that calls a procedure “P” with its two arguments being the contents of A and the address of B, using the standard procedure…
A CPU that supports little endian format reads two integer (4-byte) values from address 0x1000 and 0x2000. The values read are 55 and 6850 respectively. Please show the memory contents (byte-wise) at address 0x1000 and 0x2000?
I have this problem from my textbook that I do not understand, despite re-reading the section on segmentation and paging. "The IBM system/370 architecture uses a two-level memory structure and refers to the two levels as segments and pages, although the segmentation approach lacks many of the features described in Chapter 8. For the basic 370 architecture, the page size may be either 2 KB or 4 KB, and the segment size is fixed at either 64 KB or 1 MB. For the 370/XA and 370/ESA architectures, the page size is 4 KB and the segment size is 1 MB. What advantages of segmentation does this scheme lack? What is the benefit of segmentation for the 370?"Can you help me undertand what they are looking for in this explanation?
Answer the given question with a proper explanation and step-by-step solution. Write an assembly language program which will multiply x by y. The final answer should be stored into memory location A000H.You may assume that memory location B000H is holding the value of x, and memory location B001H is holding the value of y.Your program design must include a loop. You may assume that your program will begin execution at line 0000H.You must enter a NOP command at the end of your program to make the program stop.Enter one command per line.
Our ‘mostly 8-bit’ design has the problem that computed pointers can only range over256 bytes of memory. This makes using the screen difficult (though not impossible!). Howmight you extend the instruction set to make this easier? [Hint: think about spare bits inthe C-instruction.]
Task Write a program in the ARMLite assembly language which generates the Fibonacci number F(12) and stores the value in register R6. • You must use a loop to generate the value. Partial marks will be given for otherwise correct but non-loop based solutions • There is no limit on the number of registers you can use • The stack memory may be used, but is not required • Other memory access is not allowed or needed • Add a comment to the top of your program describing it's behaviour. You should make use of comments to describe your code's sections. Submit your program as a plain text file. If you are using the ARMLite simulator, it can be exported directly using the 'Save' button.
