i Consider the following segment of ARM assembly code. LDR LDR CMP R1, =0xDA7F0257 R2, =0x7 F 0 0 0 0 0 0 R1,R2 a) The above code segment contains two LDR pseudo instructions. Briefly explain how these pseudo instructions are translated into actual ARM instructions by the assembler. [4 marks] b) Determine the value of condition code flags N, Z, C, and V upon the execution of the CMP [4 marks] instruction. c) Based on the condition code flags found in part b), determine which of the following conditional instructions will be executed. ADDLT, SUBGE, BHI, BLS, MULNI, BHS, BGT [2 marks] d) If the CMP instruction is replaced by TEQ R1, R2 which condition code flags from part 3 marks] b) will be changed and find the new condition code flags
