To move the content of a register either to the right or

left until fully overflowed.

A bit that indicates either a positive or a negative (the

highest-order bit).

To extend a data length in which the higher-order to be

extended are made to have the same sign of the sign

bit. For example, sign-extending FF16 results in

FFFF16, and sign-extending 0F16 results in 000F16.

An area for automatic variables the functions of the C

language use.

A sequence of characters.

To restore combined items or packed information to

the original form. Used to mean to separate 8-bit

information into two parts — 4 lower-order bits and

four higher-order bits, to separate 16-bit information

into two parts — 8 lower-order bits and 8 higher-order

bits, or the like.

To extend a data length by turning higher-order bits to

0's. For example, zero-extending FF16 to 16 bits

results in 00FF16.
