Computer Science 1) Construct an equivalent ARM assembly code to the given C code without the use of conditional instructions except for branch.

A Little boolen algebra. what is the result (in t1) of the instruction xor $t1, $t0, $t0?

Show the assembly instruction for the following machine code, given in hexadecimal. Explain all fields in detail. 03A2F023

In each of the following MOV or MVN instruction, identify whether the use of the immediate value is VALID or INVALID. (a) MOV R1, #0xD017 (b) MOVW R1, #0xE689 (c) MOV R1, #0xAC5 (d) MVN R1, #0xAC5 (e) MVN R1, #996 (f) MVN R1, #0x9B000000 (g) MOV R1, #0xF300F300 (h) MOV R1, #0x1357CDEF

Describe the SBB instruction in further detail.

6. What is the MARIE instruction for the following register transfer language (RTL): MAR + X MBR + M[MAR] АС + МBR

(b) Construct a sequence of instructions such that (i) you add the 8- digit BCD number in AX and BX to the 8-digit BCD number in CX and DX. (AX and CX are the most significant registers. The result must be found in CX and DX after the addition.). (ii) Then logically shift AX right by 12 bit positions and the rightmost 12 bits of BX into the leftmost 12 bits of AX using double precision shifting. (iii) Assuming that DL= 0F3H and BH=72H , compute the answer after BH is subtracted from DL and show the contents of the flag register bit

write instruction sequence to implement: 4-byte number in data memory locations 0x15~0x12 divided by 16, and lowest byte is stored at 0x12
