TRUE OR FALSE
T F 1. The value of the mode field determines which addressing mode is
to be used.
T F 2. In a system without virtual memory, the effective address is a
virtual address or a register.
T F 3. The disadvantage of immediate addressing is that the size of the
number is restricted to the size of the address field.
T F 4. With direct addressing, the length of the address field is usually
less than the word length, thus limiting the address range.
T F 5. Register addressing is similar to direct addressing with the only
difference being that the address field refers to a register rather
than a main memory address.
T F 6. Register indirect addressing uses the same number of memory
references as indirect addressing.
T F 7. Three of the most common uses of stack addressing are relative
addressing, base-register addressing, and indexing.
T F 8. The method of calculating the EA is the same for both base-register
addressing and indexing.
T F 9. Typically an instruction set will include both preindexing and
postindexing.
T F 10. The x86 is equipped with a variety of addressing modes intended
to allow the efficient execution of high-level languages.
T F 11. The base with index and displacement mode sums the contents of
the base register, the index register, and a displacement to form
the effective address.
T F 12. The memory transfer rate has not kept up with increases in
processor speed.
T F 13. For addresses that reference memory the range of addresses that
can be referenced is not related to the number of address bits.
T F 14. The principal price to pay for variable-length instructions is an
increase in the complexity of the processor.
T F 15. One advantage of linking the addressing mode to the operand
rather than the opcode is that any addressing mode can be used
with any opcode.
