4. ARM Data Addressing. Suppose r0-0x8000, and the memory layout is as follows Address Data 0x8000 0x1A 0x8001 0x2E 0x8002 0x2B 0x8003 OxOD 0x8004 0xFC 0x8005 0xA3 0x8006 0xCD 0x8007 0xE9 ii. ARM processors can be configured as big-endianness or little-endianness. What is the value of rl after running LDR r1, [ro]? (2) a. b. If little-endianness, r1 = If big-endianness, rl= Suppose the system is based on little-endianness. What are the values of r1 and r0 if these instructions are executed separately? (3) LDR r1,[r0,#4] r0= rl= LDR r1,[r0],#4 r0= rl= LDR r1,[r0,#4]! r0= rl =

19. Which of the following is exempted from the National Electrical Code's strict grounding requirementsfor equipment?A. Frames of electrically heated appliances that are temporarily insulated from groundB. Equipment that's located in a wet or damp location and isolatedC. Distribution apparatuses mounted on wood poles that are less than eight feet tallD. Insulation that's used as a substitute for grounding and offers equal and effective safety by using double-insulated equipment

Refer to the National Electrical Code® or the working drawings when necessary. Where applicable, responses should be written in complete sentences. For problems 1 and 2, six luminaires, similar to Style E used in the Commercial Building, are to be installed in a room that is 12 ft x 18 ft (~3.7 m x ~5.5 m) with a 9 ft (2.8 m) floor-to-ceiling height. The spacing ratio for the luminaire is 1:0. 1. The maximum distance that the luminaires can be separated and achieve uniform illuminance is ft ( m). For problems 2-5, two luminaires, 8 ft (2.5 m) and 4 ft (1.2 m) in length with dimensions as shown in Figure 15-7, are to be installed in tandem (end to end). The end of the long luminaire is to be 2 ft (600 mm) from the wall. 2. The center of the outlet box should be roughed in at ft ( m) from the wall. 3. The first support should be installed at the wall. ft ( m) from 4. The second support should be installed at from the wall. ft ( m) 5. The final support should be installed at the wall. ft…
