Suppose r0 = 0 times 20008000, and the memory layout is as follows: (a) What is the value of r1 after running LDR r1, [r0] if the system is little endian? What is the value if the system uses the big-endian? b) Suppose the system is set as little endian. What are the values of r1 and r0 if the following instructions are executed separately? LDR r1, [r0, #4] LDR r1, [r0], #4 LDR r1, [r0, #4]!
Problem: On an ARM processor using big endian format, given the following memory map and [R1] = 0xA10E0C2D, [R2] = 0x00000060, [R3] = 0x00000002, [R4] = 0x0000000C, predict [R1] and [R2] and draw the updated memory map after an ARM data transfer instruction is executed in EACH case. (hint: (1) in this map, each memory location is a word long and occupies 4 bytes; also you only need to draw the section of the memory including the changed word and...
