Briefly explain Local Descriptor Table (LDT)
(b) Figure 1, shows an ARM assembly program, which finds the most positive and
negative values in a list of 16-bit (half-word) value in data memory (TABLE).
The values are in two's complement representations. By examining the program,
answer the following questions:
(i) Find the errors in the program and make necessary corrections. Do not
insert any additional line in the program.
(ii) How many bytes does 'TABLE' occupy?
(iii) What are the values loaded in the register R2 and R4?
(iv) Determine the values of the flags N, Z, C and V.
(v) Modify the program such that the numbers in 'TABLE' are represented in
'word' length.
