- Will upvote! Suppose that ES= 6DF2, DS=83AC, SS=EBD2, AX=B75, DI=DC7, BP=51A, SI=FB3, REN=75D and YEN=A8E. Determine the address accessed by each of the following instructions and state what addressing mode is used: a. MOV REN[DI][AX][9F], BX b. MOV BL, YEN[BP+SI-72A]Suppose a specific MCU has the following size of memories: 2 M byte of flash, starting from 0x0800_0000, 256 k byte of SRAM starting from 0x2000_0000, and 8 k byte registers for GPIOs, start at 0x4001_0000. (Note that 0x is the prefix for hexadecimal numbers.) Draw the memory map based on your calculations for the addresses.Draw the diagrams of given addressing modes. Show it with examples also. 1- Indexed Addressing a. Postindex b. Preindex
- Q2. The 8-bit registers AR, BR, CR, and DR initially have the following values: AR= 11010010, BR= 11100011, CR= 10111001 , DR= 10101011 Determine the 8-bit values in each register after the execution of the following sequence of microoperations. AR <-AR + BR CR <- CR ^ DR, BR <- CR + 1 AR <-AR – CRConsider the following two operations: (a) PC = PC + 4; (b) PC = PC + offset (offset is a positive or negative multiple of 4).Which of the following statements is true? a In the MIPS architecture, operation (b) is done by performing operation (a) as many times as required. b Operation (a) requires about 1/2 as much hardware to implement as does operation (b) c Operation (a) is simply done by replacing the right-most two bits of PC with 00. d Since (a) is a special case of (b), these two operations require the same hardware to implement.This question is on Computer Architecture. Translate the following arithmetic and logical expressions written in C programming language intoinstructions sequences written in MIPS Assembly language. You may assume that the values (orbase addresses) of the variables a, b, c, and d are in the general-purpose registers $s0, $s1,$s2, and $s3. 1. d[3] = a - b + c[7];2. c[5] = (a << 3) & (b >> 2);Here, <<, >>, and & indicate the bitwise left-shift, right-shift, and AND operations respectively.
