Consider the following operations: A B- C The corresponding assembly code instruction list generated by a compiler are 1 load [%r0 +4], %r1 2 load [%r0 + 8], %r2 3 sub %r1, %r2,%r3 4 load [ZrO + 12], %r4 5 add %r3, %r4 , %r5 6 store %r3, [%r0 + 16] 7 store %r5, [%r0 + 20] a) Identify the potential pipeline hazards. (10 points) b) State if the found hazards can be eliminated and if so propose a scheme...
Write C code that perform the same as the assembly code. Hint:data is an integer avariable in C. OUT is a name of a function:- //code part is the following..

What does the ADR instruction do in Arm Architecture. For example: ADR R0, R0, R1 please compare the ADR and the LDR instructions, and feel free to use your examples for any of the questions. Thank you very much.
Section B - ARM Assembly Language (25 marks) An ARM instruction set summary is provided at the end of this paper 1. (5 marks) Consider the following assembly instruction STMFD r13!, (r5-6} Before executing this instruction, registers hold the following values: Register Value Register r9 Value r4 0x00400040 0x00000000 r5 r10 0x11223344 0x00800080 r6 0x55667788 r11 0x10001000 r7 0x99aabbcc r12 0x20002000 r8 exddeeff00 r13 ex40004000 What memory locations are affected after executing the above instruction? In a table, with a...
Step 1: Create a new ASSEMBLY project using Keil Software (1) Make sure you use the M3 option Step 2: “Write an ARM assembly language program that counts the number of 1’s for any value in R0. The program must assemble/compile in KEIL and must be able to run in the KEIL simulator. Generally, R0 may contain any value, but for purpose of this exercise, you may move 0x2345ABCD into R0. The number in R0 does not need be preserved....
Explain how LDR instruction works with an example. Explain how STR instruction works with an example.
