Consider the shown map of memory. A. What are the contents of registers R1 and R2 after the execution of the following instruction? Assume that R1 and R2 initially contain OxAA00CC22 and 0x0D700050 respectively. Also, assume that the processor is using little-endian. LDRSH R1, [R2, #-4]! Address (Hex) 0D700051 B. What are the contents of registers R3, R4, and R5 after the execution of the following instruction? Assume that R3, R4 and R5 initially contain 0xFFEEDDCC, 0x0D70004A and 0x00000020 respectively, and that the processor uses little- endian. LDR R3, [R4, R5, LSR #4] Contents (Hex) F4 0D700050 E2 0D70004F CC 0D70004E 55 0D70004D 75 0D70004C A4 0D70004B AA 0D70004A 0D700049 FF 47 0D700048 20
